How far in advance should you signal before making a turn?

Signaling at least 100 meters before making a turn is critical for ensuring safety and clarity on the road. This distance provides ample time for other drivers, pedestrians, and cyclists to notice your intention to turn and adjust their actions accordingly. It allows for better communication on the road, helping to prevent accidents by informing others well in advance of your maneuver.

When you signal this early, it enhances the predictability of your actions as a driver, which is essential in maintaining traffic flow and ensuring that all road users can react appropriately. Adequate signaling distance is especially important on faster roads and in complex traffic situations where drivers may not expect sudden movements.

Shorter signaling distances, such as those indicated by the other options, may not give sufficient warning to other road users and could increase the risk of collision. Therefore, aiming for a minimum of 100 meters is a good practice that aligns with driving safety guidelines.
