Match the specific physical signals given by authorised persons (police officers and school crossing patrols) to their precise meaning or required driver action.
- Police officer: Left arm extended horizontally to the side with palm facing forwardTraffic approaching from behind the officer must stop
- Police officer: Right arm raised vertically upward with palm facing forwardTraffic approaching from the front of the officer must stop
- School crossing patrol: Circular sign held upside down, pointing towards the groundThe patrol is not ready to cross pedestrians; vehicles are not required to stop
- School crossing patrol: Circular sign held horizontally across their body as a barrierThe patrol is actively stopping pedestrians from stepping into the road; vehicles may proceed
Cevap
Left arm extended horizontally matches stopping traffic from behind. Right arm raised vertically matches stopping traffic from the front. Sign held upside down matches the patrol not being ready. Sign held horizontally matches blocking pedestrians from the road.
The correct matches reflect the exact rules in the Highway Code for signals by authorised persons. Police use a left arm horizontal signal for rear traffic and a right arm vertical signal for front traffic. School crossing patrols use an upside-down sign to show they are not ready, and a horizontal sign to act as a physical barrier against eager pedestrians.
