Railway Crossings and Special Traffic Conditions
Railway crossings
Approach a crossing prepared to stop. Stop before the stop line or barrier when: a barrier is closing or closed, a red flashing light shows, the crossing attendant signals stop, or a train is approaching. Never enter a crossing unless you can clear it completely on the far side - a queue beyond the crossing is a reason to wait. Overtaking at a crossing is prohibited. If the vehicle stalls on the tracks, get passengers out and away immediately, then try to move the vehicle and signal the train.
Special conditions
Fog, rain, snow, and ice demand lower speed, longer gaps, and smooth inputs. In fog use low beam or fog lights, not high beam. On ice avoid sudden braking and steering. At night, dip headlights when meeting traffic and when following. In tunnels, use low beam. When a special event or emergency vehicle approaches, clear the way.
Traps
Questions test whether a flashing red light plus a rising barrier means go (no - wait until the barrier is fully raised and the light stops). Another trap: whether you may cross when the far side is blocked (never). Whether you may overtake a slow vehicle just before a crossing (no).
Worked example
Your bus stalls on a crossing and a train is visible. Order: evacuate passengers away from the tracks first, then attempt to restart or push the vehicle, and use any emergency signal. Passengers before property, always.
