Drivers hours and traffic problems

ROG:

Cptkimura:
If you were stuck on the motorway due to an accident ahead and were static for an hour or more, would you be able to use that period of time as a rest? Or do you have to be at a services or somewhere off the road?

Break yes - rest no IMO

Huh. I’m surprised that’s allowed as theoretically the traffic could start moving at any moment, so while you aren’t “driving” you are still alert to the traffic situation around you as if you were.

Would it be legal to put the tacho on break in this period, or would a manual entry need to be made afterwards?
