127 Hours Explained
Marisa Jeppesen
Drivers must take a 30-minute break when they have driven for a period of 8 cumulative hours without at least a 30-minute interruption. The break may be satisfied by any non-driving period of 30 consecutive minutes (i.e., on-duty not driving, off-duty, sleeper berth, or any combination of these taken consecutively).
Drivers may split their required 10-hour off-duty period, as long as one off-duty period (whether in or out of the sleeper berth) is at least 2 hours long and the other involves at least 7 consecutive hours spent in the sleeper berth. All sleeper berth pairings MUST add up to at least 10 hours. When used together, neither time period counts against the maximum 14- hour driving window.
Drivers using a sleeper berth must take at least 8 hours in the sleeper berth, and may split the sleeper berth time into two periods provided neither is less than 2 hours. All sleeper berth pairings MUST add up to at least 8 hours.
A driver is exempt from the requirements of 395.8 and 395.11 if: the driver operates within a 150 air-mile radius of the normal work reporting location, and the driver does not exceed a maximum duty period of 14 hours. Drivers using the short-haul exception in 395.1(e)(1) must report and return to the normal work reporting location within 14 consecutive hours, and stay within a 150 air-mile radius of the work reporting location.
WHAT ARE BATTERY AMP HOURS?Amp hours indicate how long a battery can power a device before it needs to be recharged. The higher the amp-hour rating of a battery, the longer it will last before it needs to be recharged.As a rough estimate, a battery with a rating of 5Ah can deliver 5 amps of current for about one hour, or 1 amp of current for about 5 hours, before it needs to be recharged. Similarly, a battery with a rating of 10Ah can deliver 10 amps of current for about one hour, or 1 amp of current for about 10 hours, before it needs to be recharged.They are an important consideration when choosing a battery, as they determine how long the device can operate before the battery needs to be recharged.
IS A HIGHER AH BATTERY BETTER?
Higher amp-hours in a battery do not necessarily mean that it is better for every application. The right battery depends on the specific needs of the application.
A battery with higher amp-hours has a larger capacity and can deliver power for a longer duration before it needs to be recharged.
However, a battery with higher amp-hours is usually larger and heavier than a battery with lower amp-hours. This can make it less suitable for portable devices that require lightweight and compact batteries, such as handheld power tools or smartphones.
WHAT TYPES OF APPLICATIONS ARE DIFFERENT AMP HOURS USED FOR?
Low-Power Applications: Batteries with amp-hour ratings of 1-2Ah are suitable for low-power applications, and are ideal for cordless drills, drivers, radios and flashlights. These batteries are lightweight and compact, making them ideal for portable devices.
Medium-Power Applications: Batteries with amp-hour ratings of 3-4Ah are suitable for medium-power applications, such as string trimmers, reciprocating saws, circular saws, and other power tools. These batteries offer a balance between power and run time and are suitable for tasks that require moderate power consumption.
High-Power Applications: Batteries with amp-hour ratings of 5-6Ah or higher are suitable for high-power applications, such as heavy-duty power tools such as chainsaws, lawn mowers and saws.

On May 14 2020, FMCSA released a Final Rule updating current Hours of Service (HOS) regulations in an effort to increase safety for all drivers across the U.S. while workings simultaneously to improve commercial driver flexibility and satisfaction. This announcement comes just one day after the FMCSA released an extension to the HOS exemption released in an Emergency Declaration this past March.
1. CMV short-haul exception: The previous rule stated that drivers could not be on duty more than 12 hours and could not drive past a 100 air-mile radius. The new HOS rule extends the maximum duty period allowed under the short-haul exception to 14 hours and 150 air miles. Drive time remains unchanged and limited to 11 hours.
2. Adverse driving conditions: The past HOS rule stated that a driver may not drive more than 2 additional hours beyond the maximum time allotted, and it did not extend the maximum driving window. The new rule allows a driver to extend the maximum driving window by up to 2 hours during adverse driving conditions.
3. 30-minute break: The previous rule stated that a driver must take a minimum 30-minute, off-duty break before driving if more than 8 consecutive hours have passed since the last off-duty or sleeper berth period of at least 30 minutes. The new rule requires a 30-minute break after 8 hours of driving time, instead of on-duty time, and it allows on-duty not driving periods to qualify as breaks.

On April 22 I finished a 34 hour reset and started with a full 70 hour clock. Today April 29th this it what is left. This shows what hours I have available. As you can see, I have 59 minutes left on my 70. My delivery is at 07:00 tomorrow and I'm 20 minutes away.
What will tomorrow bring? The shot below shows what I did over the last 8 days. Starting on the left is what I worked 7 days ago. At midnight tonight, the eighth day begins and 4-22 was 8 days prior. So, tomorrow I get 9 hours and 55 minutes back. Add that to the 59 minutes left on the 70 and I start tomorrow with 10 hours and 54 minutes. The next day I get the 10:45 added to whatever is left. And so on down the line.
JJ Keller has a little book that is usually available at truck stops on HOS that provides all the info...the only problem with it is that it is a little cumbersome to read because all sorts of commercial drivers are lumped together in one long thing so we must jump through to find the sections applicable to us. Still, it is a handy little resource to have.
My last company I drove for (got their doors shut by DOT) had a really bad score. I got pulled in 5 times in 4 weeks after one of our drivers was involved in a wreck that killed the 4-wheeler. My first inspection showed me 15 mins over my 70....math error on my part. The inspector told me about "Recap" an app in google play. After I got that installed, no more math or other errors.
I currently have 2h21m on my 70, I get 9h27m back to deliver tomorrow 22 miles away, in Pittsburgh. My preplan will then get me to my next destination, with a reset built into my routing. I might be able to deliver Monday, and keep recapping. But we shall see. My recap hours are OK, but I had a Murphy's Law week, with load shift, trailer issues, and a few other issues.

Is kilowatt (kW) the same as kilowatt-hour (kWh)? The quick answer is no. Although kW and kWh are related, they are, in fact, completely different. In this guide, we will explain the difference between kW vs. kWh, what they measure, and why it is important to understand the difference.
It is easy to get kilowatt and kilowatt-hours confused as both are connected units of measurement. The important difference between kW and kWh is what they measure. A kW measures power i.e. the rate at which something uses electricity, whereas a kWh measures energy, the total amount of electricity used, or the capacity to use.
