When is it necessary to use turn signals?

Using turn signals is essential whenever you change lanes or make a turn as it communicates your intentions to other drivers on the road. This practice is crucial for ensuring safety and preventing accidents, as it gives other road users the opportunity to anticipate your movements. By signaling before you change lanes or turn, you help maintain a predictable flow of traffic, which is vital in both urban and rural settings.

In addition to signaling during lane changes and turns, the law requires drivers to indicate their intentions to enhance road safety. This approach not only promotes a cooperative driving environment but also reinforces proper driving behavior.

The other options were limited in scope; for instance, signaling exclusively when changing lanes would overlook the importance of indicating intentions when making turns. Similarly, restricting signals to intersections does not capture the necessity of signaling in other situations. Moreover, only signaling in city areas disregards the fact that all drivers, regardless of location, benefit from clear communication on the road.
