Speed Camera on A1 near Eyemouth

[GW]

Hello,

There is a speed camera which is facing on coming traffic on the opposite
side of the road if you are travelling from Edinburgh.

There are 3 lanes, 2 lanes going towards Eyemouth, and 1 towards Edinburgh.
THe camera is Gray on the front.

Why are there lines on all 3 lanes? I always presumed that if a camera was
facing you, it could never lead to a speeding ticket. I thought in Scotland
at least, all stationary / permanent speed cameras only catch traffic
travelling away from the camera so the picture is always of the back of the
car...

Needless to say I was doing around 80 and I think I managed to slow in time,
shit myself big time though. Still have an L plate!

Gary.
