Road works and temporary
Vehicles may not pass the temporary traffic signals when the red light is shown at a junction
What it means
The board you stop at where temporary signals are running a whole junction inside the works, not simple one-lane shuttle working. Wait at the board until your green shows - do not creep past it and do not follow the car in front through on its green. People on foot may still be crossing.
