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

Signaling is a critical part of safe driving, especially for commercial vehicles that are larger and may have more blind spots compared to standard vehicles. The requirement to signal at least 30 meters (100 feet) before making a turn helps ensure that other road users, including pedestrians and drivers, are aware of your intentions well in advance. This distance allows enough time for surrounding vehicles to react accordingly, whether that means slowing down, changing lanes, or preparing for the turn.

Using this distance for signaling is important for maintaining safety on the road, enhancing the predictability of your actions for other drivers, and preventing accidents. It also encourages good driving habits, which are essential for commercial drivers who often share the road with various types of vehicles and road users. The other distances listed may not provide sufficient advance warning for others on the road, potentially leading to confusion and unsafe driving situations.
