In this scenario, can you enter the level crossing without first checking that no rail vehicle is approaching?

Why?

Before entering a railway crossing, you must take particular care and check that no rail vehicle is approaching. The raised barriers shown do not remove this duty. Look along the tracks in both directions and approach at a speed that allows you to stop safely before the crossing.
