How many feet before making a turn must drivers signal at least?

Drivers must signal at least 100 feet before making a turn to ensure that other road users, including vehicles and pedestrians, are aware of their intentions. This practice is crucial for promoting safety on the road as it provides adequate warning time for others to react to the driver's actions. Signaling well in advance allows neighboring drivers to adjust their speed or position to avoid any potential hazards.

The requirement for signaling at least 100 feet is grounded in the need for clear communication among road users, which is essential for maintaining traffic flow and preventing accidents. This guideline helps establish predictable driving patterns, making it easier for everyone on the road to anticipate movements and respond accordingly.

Shorter distances, such as 70, 50, or even 30 feet, would not provide enough time for other drivers or pedestrians to notice the intention to turn, potentially leading to confusion or collisions. Therefore, the 100-foot signaling practice is designed to enhance overall safety and visibility on the roadway.
