What is the purpose of turn signals?

Turn signals are crucial for road safety as they communicate a driver's intentions to others on the roadway. When a driver uses turn signals, it indicates to other motorists and pedestrians that they plan to turn or change lanes. This clear communication helps to prevent accidents by allowing other drivers to anticipate and react to the upcoming maneuver, ensuring smoother traffic flow and enhancing overall safety.

While alerting pedestrians and notifying other drivers about speed may contribute to road safety, these are not the primary functions of turn signals. The primary goal is to facilitate clear communication regarding lateral movement, fostering a more predictable driving environment for everyone sharing the road.
