BDifficulty 3/5

A square lane-control signal positioned above a lane, with no panel indicating another lane, affects...

Correct answer

The vehicles travelling in the lane over which it is situated.

All vehicles travelling in that lane, rather than only cars or the whole carriageway. Under Annex I section 4.3 of the General Traffic Regulations, a red cross prohibits occupying the lane and requires leaving it as soon as possible. A downward green arrow permits using it but does not cancel other duties to stop or give way. A diagonal white or amber arrow indicates that you must safely move into the indicated lane because the current lane will close.
