You need rest. Are you allowed to pull over for a short while on the presented hard shoulder?

Why?

A solid P-7b edge line is visible on the right. Stopping alongside this line is prohibited both on the carriageway and on the shoulder. Needing a rest does not override the prohibition, so you must use a car park or another permitted stopping place.
