How far ahead should you signal before turning?

Signaling at least 100 feet before turning is important because it provides adequate notice to other drivers and pedestrians of your intentions. This distance allows those around you sufficient time to react to your movement, enhancing safety on the road. Signaling well in advance is particularly crucial in situations where traffic is heavier, or visibility is limited, as it helps prevent accidents by ensuring other drivers have enough time to adjust their speed or position as necessary. Using this standard of 100 feet aligns with widespread traffic regulations and helps ensure smoother traffic flow.
