Final answer:
Using turn signals during turns improves road safety by alerting other drivers and pedestrians of a vehicle's intent, allowing others to adjust accordingly. This practice, along with traffic signals, helps to regulate traffic flow, decreases the risk of accidents, and enhances pedestrian safety.
Step-by-step explanation:
Giving a turn signal when you initiate a turn is considered an important practice for road safety, especially in terms of allowing vehicles behind to adjust their speed in time. The use of turn signals provides communication to other drivers and pedestrians about the intentions of a vehicle, which is critical for preventing accidents. When vehicles speed through an intersection without regards to the posted speed limit and without signaling, the risk of accidents increases significantly. The presence of a traffic signal can considerably reduce this hazard by regulating traffic flow and ensuring drivers reduce their speed accordingly.
Moreover, pedestrian safety is greatly enhanced when turn signals are used and when traffic signals are in place. Pedestrians, including students going to or coming from campus, must be able to cross roads safely. Traffic signals facilitate this by providing clear timing as to when it's safe to cross. In areas where the number of accidents has risen beyond an acceptable limit, with some resulting in loss of life, the implementation of a traffic signal becomes a necessity for improving overall traffic safety.
In summary, consistent use of turn signals and the installation of traffic signals at busy intersections have far-reaching effects on reducing accidents. They provide clear communication and control to all road users, which is paramount for the prevention of collisions and the safety of pedestrians.
