Final answer:
When a car's signal light is not working, you should use a hand signal for a right turn by raising your left arm at the elbow. Drivers must respect speed limits and pedestrian safety at intersections. Traffic signals are proposed to reduce collisions and improve safety.
Step-by-step explanation:
If your signal light is not working, you must use hand signals to indicate your intended maneuvers to other drivers and pedestrians.
To make a right turn, you should extend your left arm out of the window and bend it at the elbow, so your hand is pointing upwards.
This universal hand signal suggests that you plan to make a right turn. It's essential to always ensure your intention to turn is clear to others to maintain road safety.
Regardless of the situation, even if a traffic signal is not present or is not functioning, drivers are responsible for obeying the posted speed limit and should never speed through intersections.
Pedestrian safety at intersections is crucial, especially near campus areas where pedestrian traffic is high. Moreover, accident statistics and safety concerns are substantial reasons for the implementation of traffic signals to reduce the frequency of collisions and enhance overall safety for all road users.
