I know its an EU thing , but whats the logic - if any - behind limiting
trucks to 56mph but buses & coaches to 70? If a 15 ton bus full of passengers
crashes it'll cause a damn site more injuries than a 15 ton lorry full of
potatoes so why does the lorry have to go so slow? As a car driver I'd much
prefer them so be able to do 70 so we don't get the miles on end of mobile
roadblocks on the motorways.

Because bus passengers have a choice, but fifty pallets of washing machines
don't.

Or, to put it another way, buses weren't restricted because it was felt
that doing so would be likely to discourage people from using them and
cause them to favour driving instead. But freight can't go by car, so
making all freight go a bit slower isn't going to result in any modal shift
away from HGVs.

The original reason for the EU limit was nothing to do with safety, it's to
do with reducing fuel consumption. The UK government at the time spun it as
a safety measure, partly bcause they felt it would be more palatable to the
public and partly because there have recently been some well-publicised HGV
crashes and the limit could, conveniently, be put forward as something
being done.

So, I think, would most drivers.

Sounds believable. Though if they really wanted to do something about HGV
fuel consumption changing the barn door profile of the front end would be a
damn sight more effective.

A bit more creatively, it could also be made an offence for the driver
of a lorry which is being overtaken by another lorry not to slow to let
the overtaker back into the nearside lane straightaway.

I suggest six penalty points either way, to reflect the danger of
rear-end collision.

You are, I presume, comparing the speed limiter settings as you mention
56mph for trucks. They are limited to a set speed of 85kph and a
stabilised speed of 90kph by their speed limiters. This equates to
56mph despite the fact that the speed limit for that class of vehicle is
60mph on a motorway. Similarly a coach must have a speed limiter fitted
limiting it to a speed of 100kph or 62mph. The speed limits which apply
on a motorway are 60mph for a vehicle of over 12 mtrs in length and 70
mph up to 12 mtrs. Irrespective of speed limits the speed limiter will
prevent speeds over 100 kph under normal circumstances. I don't need to
Google it to know this.

them to do that legally, their motorway speed limit is the next higher

You either forget or are unaware that there are length restrictions on
trucks. Make the front longer, you have to recoup that length somewhere.
Which means less load space.

B'sides, do you not think the manufacturers might have thought of that
already?

The speed limit on a motorway for a PCV is 70 mph. All PCVs that are of
an age likely to be in regular use *must* have a road speed limiter
fitted set to a speed no higher than 100kph.

It is possible and legal for a coach to be travelling downhill at 70
mph, but as soon at the road starts rising or is flat again, the speed
will drop.

NatEx follow the same rules as the rest of us, and in my 35 years of
driving coaches in the UK and abroad, I've *never* know a NatEx coach to
exceed the legally required set speed by more than a couple of miles per
hour, unless he's been driving down a steep motorway bank such as the on
on the M40 North of High Wycombe. Even in the days before limiters, in
my experience they very rarely broke the motorway speed limits.

National Express must be buying their speed limiters from a different
supplier than every other coach company then! Either that or their drivers
are overriding the limiters somehow.

On the A3 between London and Portsmouth you can see them regularly doing
~70mph on flat stretches, tailgating, then holding everyone else up on
uphill stretches etc. Their drivers are arseholes. There is no way they (the
ones I've seen) are limited to 62mph. I concede that downhill they're liable
to exceed their limiter but you simply can't maintain that speed on a flat
stretch with a working limiter, it won't let you. Especially with the weight
and wind resistance of a coach.

I can't recall seeing any other coach doing that kind of speed, it's always
the National Express ones. Presumably there's some kind of penalty for not
getting somewhere quick enough.

Considering that any vaguely recent coach will have the limiter as part
of the engine management, and every coach - as HGV - has to have the
limiter checked and recalibrated regularly, it's very unlikely.

Entirely possible, within the permitted margins of error. The coach
limiter could be set at anything up to 107kph ~ 66mph. The car speedo
could be showing 70mph at anything from 58mph to 70mph.

No one is checking MentalTwat's speedometer. It's permissible for it to
over read by 10% + 2mph. At 62 that means his speedo could read 62 + 6 + 2
= 70 mph.

Same goes for Bloater.

Have you never noticed how many artic cabs have wind deflectors _on top_
of the cab, smoothing the airflow over the trailer?

B'sides, think about the lower rooflines of HGVs with day cabs rather
than sleepers. Do you think there might be a functional reason for that
taller roofline, p'raps related to the bed height in the back of the cab
over the engine?

Even if that was the case, which it isn't, then don't you think that an
infinitessimal increase in manufacturing cost which results in a
significant reduction in running costs might, just p'raps, result in an
equally significant increase in market competitiveness and thereby sales
volume?

Do you deliberately keep reminding me regularly of Duhg, with his line
about his complete and utter ignorance of facts being an advantage in
allowing him "free thinking"?

You really ought to write to Mercedes, Scania, DAF or any of the other
big truck manufacturers - with you on board, in place of all those
useless tossers who currently staff their product planning and
aerodynamics teams, the entire market could be theirs so easily!

And what? A barn door with a wind deflector is still a barn door. Increase
the height of the cab but slope the front, much more efficient.

No. You ever been inside a cab? The bed is more or less seat level.

Its amazing what you trolls can learn by correspondance course under

None of them will do anything until the others do. And I imagine designing
a whole new cab layout is pretty expensive so the price would be high and
it might not sell.

Go and play with, f'rexample, the truck configuration tool on DAF's
website. Both their "larger" ranges, CF and XF, offer a variety of cab
sizes. Only the largest has that big step above the windscreen.
Now look at the position of the steering wheel relative to that
windscreen, and an interior shot with the overhead console (well within
the driver's reach).

How much space is there to lose...?

Here's a clue.

Go and look carefully at a line drawing of a truck cab. Now draw lots of

So how and why do manage they launch new cab designs every few years?

It's clearly got you confused for a start...

Para 1
"...thanks to new legislation"

Para 2
"New proposals for greater freedom in truck design"

Para 3
"The European Commission proposals would adapt the Weight and Dimensions
Directive to allow truck designers to create more rounded shapes and add
aerodynamic flaps. A current maximum combination length of 18.75 metres
would be increased, provided the increase is in the cab section."

The only legal requirement for a car speedometer is that, when fitted,
it must read no more than 10% higher than actual speed at 30mph. I have
checked a random selection over the years against measured miles using a
stopwatch, and found errors at 60 mph ranging from +7% (Most Fords) to a
Renault which over-read by 30%. All were legal.

Next time you see it happen, feel free to contact the police or the
operator giving them the registration number, and the time and location
of the alleged offence. The facts will very likely be checked, and it
will almost (As in 99% of the time) invariably be found that the law has
not been broken. On the other occasion, they will find a defect that
will be repaired within 7 days.

That must include the hundreds of coach drivers I work with who are
constantly whinging about the fact that the coach they've been driving
that day will only do 99kph on the flat.

Just to clarify matters, I am a coach driver, so I *know* what speed
they will do from personal experience. The last time I drove one that
would exceed 70 mph on the flat was in about 1990.

Then compulsory speed limiters were introduced, and all coaches started
magically and annoyingly travelling at the new mandated maximum set
speed of 70mph, and when the limiters were required to be set at 65mph
and then 62mph, it only took a few months for all of them to be
adjusted, at which point we were all driving at the new limits.

I'm sorry but that's not correct. I'm not sure if it ever was correct.

C & U Regs 1986 refer to EU directive 75/443/EEC which states:

4.3.5. the vehicle is tested at the following three speeds : 40, 80 and 120
km/h, or 80 % of the maximum speed specified by the manufacturer, if this
is inferior to 150 km/h;

The speed tolerances permitted are that the speedometer cannot indicate a
speed lower than the true speed and must confirm to the 10%+2mph (actually
4 km/h) as I said previously.

Which says, inter alia, that...

The European Commission proposals would adapt the Weight and Dimensions
Directive to allow truck designers to create more rounded shapes and add

That rather supports the view that the reason it can't be done at the
moment is because it isn't practical within the current build regulations.

You will also note, if you care to read the article closely, that the
images which illustrate that article are from the manufacturers, who seem
to be a few years ahead of you when it comes to considering the
possibilities of more aerodynamic HGVs. What has been holding them back
from poutting their ideas into reality has not been a lack of technical
ability, but rather a lack of regulatory freedom.

So you don't need to look at the evidence that the extra space is
optional, and specifically chosen by the operators. Who are the ones
paying for fuel.

And, if you recall, you've been arguing that the restrictions are NOT

Really? Well on the flat sat nav speed indicators don't lie - unlike bus
drivers. I saw 70mph following a nat exp bus only a few months ago so I don't
give a shit what they're supposed to be limited to, what they ARE limited to
is another matter.

How can the law be broken if the limit is 70? Either the legal limit for
buses under 12 metres is 62 or its 70. It can't be both. Currently the law
says 70. Ergo no law has been broken.

And the last time The Sun took up this cudgel, they showed a grainy
picture of a car speedometer reading 80mph with a NatEx coach in view.
This proved absolutely nothing.

I repeat my request. If you think you see a coach exceeding its speed
limit, please pass the details on to the police. As an industry, we
don't want to have coach drivers breaking the law. Even better, contact
one of the Red Top rags with full details, and we'll see it all over the
papers again, until their fraudulent ways are shown up again and they
have to climb down.

Apart from the law on the fitting, maintenance and calibration of speed
limiters - which says 100kph.

Adrian put finger to keyboard:
The difference being that the limiter that must be fitted by law does
*not* limit the vehicle's top speed in all conditions i.e. downhill. So
they are two distinct laws (speed limiter and speed limit) and it is
possible to break one without breaking the other; Neil's assertion that
"it can't be both" is based on the false premise that the speed limiter
law is a speed limit law.

Just to clarify further, a coach travelling downhill on a motorway at
over 70mph is breaking the law relating to its speed limit.

A coach travelling on the flat or uphill at more than 100kph probably
has a defective speed limiter, so the company would be breaking the law
relating to the fitting and maintenance of speed limiters.

That should be clear enough for even Harry to grasp.

Again I say to him, next time you see this happening, give the full
details to the police, and they will take the appropriate action. Any
such action can only help road safety by removing illegal vehicles and
law breaking drivers from the road.

I'm also a coach driver and I used to drive for National Express and I can tell you from personal experience that the vehicles go no faster than 62 mph. I can also tell you that my old car showed an indicated 68 mph when the tomtom satnav shows a steady 62 mph. So anyone who claims coaches are speeding is either mistaken or the coach was going downhill. My coach driving is now limited to a casual basis - a few coaches that i drive do go a bit faster than 62 but within the 5% tolerance for non digi tacho vehicles.

They will do 70 or more down some steep hills, but never on the flat or

I'm not making any accusations , I'm stating a fact. The chances of both
the satnav and the car speedo being out is close to zero and they both
read about 70mph.

I'm not whining about it. If you'd bothered to follow this thread from the
start you'd know I was asking why lorrys can't legally go as fast as buses
given that a loaded bus having an accident is far more likely to cause injury
and death than a lorry.

Easy. Buses and coaches are much more stable and have more predictable
handling than lorries, so the chance of them being involved in an
incident is much lower per mile. As for having less potential for
causing injury and death, look for hazchem labels on lorries, and
condsider that most loads that are labelled as hazardous can hurt or
kill a darn sight more than 100 people if there's an incident. Some have
the potential to kill or injure thousands.

PCVs were, and mostly still are, tested for stability with a full load
when they're made. Lorries generally have a higher centre of gravity,
which is not certified to be low enough to permit a tilt of 30 degrees
before falling over.

There's also the way that passengers whinge like mad if you don't go
fast enough for their liking, while freight (mostly) just sits in the
back not doing anything much. Then add the way that travelling at 90kph
with a large commercial vehicle reduces the fuel bill by about 20%
compared with travelling at 100 kph. I have verified this by experiment.

Speedo by law cannot underread so the sat nav is likely to read less.

Trains can go much faster than the legal limit for cars in the UK, can carry hundreds of passengers and there is no requirement for them to have a seat never mind a seat belt. So using your first point as there is so much potential risk to life these should be speed restricted to 50 mph immediately !!

Hmm. Even if a loaded fuel tanker blew up in the centre of a town , never
mind a motorway, I doubt it could injure thousands. And really nasty loads
- eg nuclear waste - tend to go by train. But I take your point.

There is that. However it doesn't explain why trucks across the pond are
allowed to do 70 or even 80. Though that does have its down side as this
video nicely demonstrates. Skip to 3:25.

Given the rules for carrying nuclear waste, the worst that's likely to
happen in an accident involving it is having to use a crane to put the
intact, undamaged, container onto a different lorry.

The really nasty loads are things like chlorine and hydroflouric acid.

Some commercially useful chemicals can contaminate watercourses to an
extent where carrying them are forbidden in Germany in areas containing
watercourses which deliver drinking water. I've even seen the warning
signs on autobahns.

It's not universal, and if you compare traffic density in the USA with
traffic density in the UK, it's nowhere near as busy. Just look at video
of rush hour in, say Los Angeles and compare that to Birmingham or
Manchester, never mind London.

There are very few countries with more vehicles per road mile than the UK.

I do the M25 M11 to M3 quite often at 3AM. It's very light on traffic at
that time.

Believe it or not, the quietest I've ever found the M25 was one summer
Friday afternoon, at around 4.30pm, between J8 and J15. The traffic in
my direction gradually seemed to evaporate, and on one occasion, I could
see no one behind me and only one car in front. It was quite spooky -
almost as though I'd slipped into a parallel universe.

I suspected that there might have been a massive pile-up behind me, and
that the motorway was blocked - but no - there were no reports of any
significant M25 traffic problems all that evening. It was only when I
got to J14 that the traffic started to build up again, and after J15 (M4
junction) it was back to its Friday rush-hour normal self.

I *really* hope hydroflouric acid doesn't get transported by road. Its

How do you think it gets to where it's used? I suspect pretty much all

He's right, it's properly nasty stuff, worth keeping away from. If a
lorry tank broke, it would probably kill a few people, with the
potential for "a lot" in a busy area. Fortunately they're designed not to.

I'd be leery of working with it, but safe systems of work have been
devised so it's not too bad.

The HSE leaflet there merely says the risk of HF acid from burnt o-rings
isn't that big a deal.

In a past life I did chemistry so I'm fully well aware of what certain

That is about HF gas (and fluroelastomers) rather than HF acid.

There are at least two major UK users of HF in the North West, and even
if they both produce (anhydrous) HF on site, and any waste will be
transported by road as dilute HF acid. As is the UF6 to/from one of them.

i agree with a hgv being over taken should slow to allow vehicle over taking to pass but instead of trucks being banned from overtaking at certain times....stick 56mph limit on idiot car drivers...

Or else make it an offence for the overtaking driver not to abort the
manoeuvre if he finds that he can't go significantly faster. Maybe base it
on a time limit: assuming that the overtaking lorry is not limited by
traffic in front of him, he should complete his manoeuvre within x seconds
or else abort it.

Better still, make lorries sufficiently powerful that they can all achieve
the speed limit and make sure that speed limiters are all set very
accurately to the same value so that one lorry driver knows that it will be
physically impossible for him ever to overtake another one and therefore he
shouldn't even try.

The problem is not with a lorry overtaking a tractor at 30 or slow lorry at
40. It's when lorry A, at 56.1 mph, tries to overtake lorry B at 56.0 mph.

Maybe allow lorry drivers a few seconds' exemption from the 56 mph limit in
order that they can overtake as soon as possible.

There are sections of two-lane trunk road, such as the A1(M) between the M18
and the A64 in Yorkshire, or the A34 in Oxfordshire, where cars can never
get above 56 mph for tens of miles because first one and then another lorry
pulls out into the path of traffic that wants to do 70.

Why? What's idiotic about car drivers wanting to drive faster than 56 mph
when it is safe to do so?

That idea has come up more than a few times and its a very good one. Which
means there's little chance of it being implemented by the EU or its DoT

I'm surprised that the A1 hasn't got a "no HGVs in Lane 2" rule like the A34
on the Berks/Ox border and the M42 around Tamworth have.

I have often drive the whole length of the A34 between M4 J13 and M40 J9 in
a queue of Lane 2 traffic that can't get past leapfrogging lorries. As soon
as one pulls in, another ahead of it pulls out. I've also been alongside a
lorry, overtaking it, when it has indicated and immediately pulled out into
my path. If you or I failed to notice a car on our right as we pulled out,
and got a long blast on the horn and headlights "watch out, I'm already
here", we'd pull back in - not so for lorries which use their size to barge
their way out, regardless of the fact that there is a car there.

Yeah, been in that sort of situation. It rather puts the whole aura of
"professional driver" that these guys like to project into perspective as the
joke it is. Any idiot who can drive a car without putting it into the nearest
post has the skill to get an HGV license - I've got one!

These guys should watch some of the crash videos on youtube. A collision
between a lorry and a car doesn't always end well for the lorry driver either
if the vehicle overturns or goes off an embankment.

It's not the fact that they keep overtaking each other that really annoys
me. It's the fact that they take a long time to do it, sitting alongside the
lorry that they are overtaking for several minutes because of the very low
differential speed.

It cannot be easy driving a vehicle that has a very low
power/torque-to-weight ratio (and hence very poor acceleration) and which is
severely speed-limited. But that is what they are paid and trained to do -
how to drive safely *and with due consideration for other traffic*.

I've very occasionally found myself in the situation where my car runs out
of power when I'm trying to overtake, and I end up going no faster than the
vehicle I'm trying to overtake. But as soon as I realise what's happening,
I'll ease off the power or else brake so as to pull back behind the other
vehicle again, to have another go when I've got the gradient in my favour. I
don't sit there thinking "the longer I do this, the more likely I am to get
past" :-)

If I'm driving close to the speed limit and I come up behind a car that is
going fractionally slower, I don't immediately think "I must overtake",
especially if there is a lot of traffic in Lane 2 which is clearly going
much faster than I want to go. I may decide that 69 is as good as 70 mph, if
the alternative is to speed up to maybe 80 to match the speed of traffic in
Lane 2 until I've got past. But there must be something in the lorry
driver's mentality which says "I must go at 56.0 mph - 55.5 won't do".


To go back to the OP's question, I wonder if the fact that buses and coaches
are rigid vehicles whereas many lorries are articulated has any bearing on
the different speed limits? I presume articulated vehicles are more likely
to become unstable at high speed than rigid ones, if there is a crosswind
and the lorry starts to snake.


The other thing that gets me is the steep 1:4 hill (Sutton Bank) near me
which articulated HGVs are allowed to use but caravans are banned from
using. Almost every week (*) the hill is closed because yet another HGV has
got stuck on the hairpin bends (either because of the tightness of the bend
or else the steepness of the hill - I'm not sure which). And all HGVs have
to take the hill exceptionally slowly eg 10-20 mph when a car can do the
straight bits (though not the tight bends!) at maybe 40 mph.
The hill really isn't suitable for HGVs in the same way that it's not
suitable for caravans. It doesn't help that the road is a bit too narrow for
cars to be able to do a U turn if they find that the road ahead has been
blocked by yet another HGV. The excuse that the Highways Authority give for
not banning lorries is that it is an important route to the towns nearer the
coast and that (unlike caravans) there is no suitable alternative route.
Which is fair enough, as long as they make it clear that lorries (and their
drivers) must be capable of getting up the hill, with those that don't being
subject to a large "you'll never ever do this again" fine - such as
confiscation of the offending vehicle!

Perish the thought that hauliers might actually use vehicles that are suited
to the size of roads that they are using - eg smaller vehicles on the Sutton
Bank route.


(*) On the Google Streetview 2015 photo https://goo.gl/maps/TdYa1SuQUM22
they record that there were "74 blockages by HGVs last year" and on the 2011
photo it was 132 which is an average of one every three days.

I've no idea what the original thinking behind the speed limits is, but the
yanks & canadians don't seem too concerned. Trucks there regularly do 75-80mph
if my experience is anything to go by.
