Where are you not permitted to overtake?

Answer: B — At a pedestrian crossing

Overtaking at a pedestrian crossing is prohibited to ensure the safety of pedestrians. These areas are specifically designated for individuals to cross the road, and overtaking vehicles in these zones creates a significant risk of accidents. Pedestrians may be in or approaching the crosswalk, and drivers need to maintain vigilance and prioritize pedestrian rights. By preventing overtaking at pedestrian crossings, traffic regulations aim to protect users of the road who are often more vulnerable, thereby promoting safer driving practices and a more accident-free environment. The other choices relate to contexts where overtaking might be allowed under certain conditions, though specific rules apply. For example, on a multi-lane road, overtaking can often be done safely in designated lanes. On highways without a speed limit, overtaking might be permissible where visibility is good and there are no prohibitive signals. Lastly, before a traffic signal, overtaking might be allowed if the signal indicates it’s safe to do so, provided that all other traffic rules are followed. However, the critical nature of pedestrian safety makes pedestrian crossings a clear no-overtake zone.
