When must you signal your intent to turn?

Signaling your intent to turn at least 100 feet before making the turn is important for several reasons. This distance allows other drivers, pedestrians, and cyclists to see your signal in time to react appropriately. It is a key safety measure that helps prevent accidents by clearly indicating your intentions on the road.

By signaling well in advance, you provide ample time for other users of the road to adjust their speed or position if necessary. This courtesy helps maintain smooth traffic flow and reduces confusion about your actions.

The other options fall short of this important safety standard. Signaling too close to the turn may not give others enough time to respond, increasing the risk of collisions. Additionally, only signaling if there is other traffic present fails to account for the need to communicate your intentions to all road users, ensuring everyone's safety.
