When should you use your turn signal?

Using your turn signal is essential for communicating your intentions to other drivers on the road, promoting safety and awareness. This practice should always be followed whenever you are changing lanes or making a turn, regardless of the time of day or the presence of other vehicles. It allows motorists around you to anticipate your actions, helping to prevent accidents and ensuring smoother traffic flow. Turn signals are not just a courtesy; they are a fundamental part of safe driving protocol.

The other options suggest limited or situational use of turn signals, which does not align with the best practices for driving safety. For instance, using signals only at night or only when other cars are present fails to account for the necessity of informing all road users of your intentions at all times. Therefore, consistently using your turn signal when changing lanes or turning is a key practice that enhances road safety for everyone.
