At what distance should you turn on your vehicle's turn signal before making a turn?

Turning on your vehicle's turn signal at least 100 feet before making a turn is important for ensuring the safety of all road users. This distance allows for sufficient visibility and provides other drivers and pedestrians adequate time to react to your intended maneuver. It helps communicate your intentions clearly, which is crucial in maintaining traffic flow and reducing the risk of accidents. By signaling well in advance, you give other drivers the opportunity to prepare for your turn, especially in busy traffic situations, thereby promoting a safer driving environment.
