When is it necessary to use your turn signals?

Using turn signals is crucial for maintaining safety and communication on the road. The requirement to signal when changing lanes, turning, or merging is essential for alerting other drivers and road users about your intended actions. This helps prevent accidents and promotes the smooth flow of traffic.

When changing lanes, a driver must signal to indicate their intention, allowing others to anticipate their movement and adjust accordingly. Similarly, signaling when turning lets nearby vehicles and pedestrians know what direction you will take, thereby reducing confusion and potential hazards. Merging into traffic also necessitates signaling to ensure that other drivers can accommodate your entry safely.

In contrast, the other options are limited and do not encompass the broader rules of road conduct. For instance, signaling only in parking lots disregards the necessity of indicating maneuvers on public roads where the majority of driving occurs. Saying that signaling is only required when pedestrians are present overlooks the safety concerns for all road users, not just pedestrians. Moreover, the notion that turn signals are not legally required is inaccurate, as traffic laws universally mandate their use during specific driving actions to enhance road safety.
