When traveling under 40 miles per hour, how far should you signal before making a turn?

Signaling at least 100 feet before making a turn when traveling under 40 miles per hour is important for several reasons. This distance ensures that other drivers and pedestrians have sufficient time to notice your intention to turn, allowing them to adjust their movements safely. Signaling too late can lead to confusion and increase the risk of a collision, as other road users may not have enough time to react appropriately.

Providing an early signal also contributes to safer driving practices overall, fostering better communication on the road. It is a common standard in many jurisdictions, aligning with safe driving principles and encouraging drivers to alert others well in advance of their maneuver. This practice helps maintain an orderly flow of traffic and can prevent accidents.
