Road markings

Under-taught everywhere and worth roughly a fifth of the signs section.

RTM1 is a stop line. Driving in A, you must stop before the line, then drive on when it is safe.
A no crossing line. Traffic may not overtake or cross it from either side.
A single X marking warns of a level crossing with one railway line ahead.
RTM3 marks the pedestrian crossing, the lines between which pedestrians walk.
