When must drivers use turn signals?

Drivers are required to use turn signals before making any turns or lane changes to communicate their intentions to other road users. This practice is crucial for maintaining safety on the road, as it allows other drivers, pedestrians, and cyclists to anticipate the actions of the signaling driver and react accordingly. Using turn signals helps facilitate smooth traffic flow and reduces the likelihood of accidents.

For example, before turning at an intersection or merging into another lane, signaling gives ample warning to others, ensuring that everyone on the road is informed about potential changes in movements. This rule is comprehensive, applying to all types of turns and lane changes, thus enhancing overall road safety.
