At what distance must you signal before making a turn?

The correct answer is based on the importance of signaling in advance to ensure the safety of all road users. Signaling at least 30 meters before making a turn provides adequate warning to drivers behind you as well as pedestrians and cyclists. This distance allows other road users to anticipate your actions and respond accordingly, maintaining the flow of traffic and reducing the risk of accidents.

Signaling too late can lead to confusion and potentially dangerous situations, as other drivers might not have enough time to react if they are caught off-guard. The distance of 30 meters strikes a balance between sufficient notice for others and practicality for the driver making the turn, ensuring your intentions on the road are clearly communicated well ahead of the maneuver.
