What must pedestrians do when an emergency vehicle approaches with its beacons and siren on?
Explanation
Pedestrians, like drivers, must give way to emergency vehicles. That means not stepping onto the road, and if already on the carriageway, leaving it as quickly as possible.
KET reference: KET 47: when an emergency vehicle with its blue and red (or blue only) beacons and special siren on approaches, pedestrians must not step onto the carriageway, and those on it must leave it at once.
