What do you do at a level crossing when the barriers are closed?

You answered correctly. When the barriers at a level crossing are closed, you must wait before the St. Andrew's Cross, making sure you do not block intersections or junctions. This ensures traffic flows smoothly and safely even while waiting. If it is dark, switching on your side lights makes your vehicle more visible to other road users, which increases safety. You should never wait directly in front of the barrier, as this can be dangerous and is not permitted. These rules help prevent traffic jams and accidents near level crossings.
