At what distance should a driver signal before turning?

A driver should signal at least 100 feet before turning to ensure that other road users are adequately informed of the driver’s intention to change direction. This distance allows sufficient time for other vehicles, cyclists, and pedestrians to react to the impending turn, promoting safety on the road.

Signaling early is essential as it provides clear communication with surrounding traffic, which helps prevent misunderstandings and possible accidents. A distance of 100 feet is particularly effective in various driving conditions, including urban areas with more traffic or in situations where visibility may be limited.

The other distances mentioned may not provide enough warning for other drivers, particularly at higher speeds or in congested areas, where 50, 75, or even 150 feet could either be too little or adequate depending on the context, but ultimately, 100 feet is the standard to maximize safety.
