Final answer:
A traffic signal is a sign that alerts drivers of potential dangers ahead and gives them time to minimize risk.
It helps slow down vehicles and improves pedestrian safety by allowing them to cross at appropriate times.
Step-by-step explanation:
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users.
The basic traffic light rules that you must know while you are at a traffic signal are:
- At the traffic signal, a red light means stop, that is you need to bring your vehicle to a complete halt.
- At a yellow traffic light sign, you must slow down your vehicle.
- The green traffic light sign means you can keep driving.
One of the signs that tell drivers of a possible danger a short distance ahead and allows the driver time to safely minimize risk is also a traffic signal.
By slowing down vehicles, a traffic signal prevents them from speeding through intersections and gives drivers time to react and avoid potential accidents.
Additionally, a traffic signal also enhances pedestrian safety by allowing them to cross at appropriate times, reducing the risk of accidents.
