A cyclist wishes - without dismounting - to cross the road at a pedestrian crossing. What should you do?

At a pedestrian crossing (zebra crossing), you must give way to pedestrians and also to anyone who is using the crossing in a pedestrian-like way. A cyclist who rides across without dismounting is technically not a “pedestrian” and does not have the same clear legal priority as a person walking a bike, but you still have a duty of care and must not endanger them.

That’s why allowing the cyclist to cross is the correct behavior: slow down early, be prepared to stop, and let them go. Honking and driving on would be wrong because the horn is only for warning of danger, not to force your right of way. Braking only at the last moment is also wrong because it surprises following traffic and increases the risk of a rear-end crash; the rule of thumb is to approach crossings with anticipation so you can stop smoothly if someone enters or is about to enter the crossing.

For similar questions: At zebra crossings, always be ready to yield. If there’s any doubt whether someone will cross (pedestrian, child, or cyclist), prioritize safety and let them pass.
