Sample question from test 9
signals-markings
What movement do traffic signals control at intersections?
- The movement of vehicles and pedestrians
- Only the movement of commercial vehicles
- Only pedestrians outside crosswalks
- Only vehicles entering from private roads
Answer: The movement of vehicles and pedestrians. Traffic signals organize the movement of both vehicles and pedestrians at intersections. They remove guesswork about who may proceed, although a driver must still enter cautiously and yield when needed to prevent a collision. The commercial-vehicle choice is too narrow because the signals govern ordinary motorists as well. The pedestrian-only choice ignores vehicle movements, and private-road traffic is only one possible approach. Watch the signal, crosswalk, and intersection together, then follow an officer's direction if an officer is controlling traffic.
