When is a driver required to give a turn signal?

A driver is required to give a turn signal at least 100 feet before making a turn or lane change to provide adequate notice to other road users of their intentions. This advance warning is essential for maintaining safety on the road, as it allows other drivers, cyclists, and pedestrians to anticipate the driver's actions and react accordingly.

By signaling in this manner, the driver communicates their plans effectively, helping to prevent accidents and misunderstandings. It ensures that anyone behind or beside the vehicle is aware that a change in direction is forthcoming. Adhering to this protocol is a critical component of safe driving practices and is part of the legal requirements in many jurisdictions.
