How far ahead should you signal before making a turn?

Signaling before making a turn is crucial for safe driving and communication with other road users. The guideline to signal at least 100 feet before making a turn provides sufficient time for other drivers to react and adjust their speed or position accordingly. This distance allows both the driver making the turn and vehicles behind them to be aware of the impending action, reducing the likelihood of collisions and ensuring a smoother flow of traffic.

In many jurisdictions, the 100-foot distance is based on average reaction times and driving speeds, creating a balance between being timely with your signal and providing adequate notice. This practice enhances overall safety and is a key part of responsible driving behavior.
