How far in advance should you keep your turn signals on before changing directions?

Keeping your turn signals on at least 100 feet in advance of changing directions is important for several reasons. This distance gives other drivers and pedestrians ample time to notice your intention to turn or change lanes. Adequate signaling helps to prevent confusion on the road, enhancing overall safety. It ensures that surrounding vehicles can adjust their speed or position accordingly, reducing the likelihood of accidents. The 100-foot distance is a standard recommendation that aligns with safe driving practices, allowing for clear communication on the road.

In terms of the other distances, while they may seem reasonable, they do not provide enough advance notice to those around you, which could lead to unsafe driving conditions. Maintaining the practice of signaling 100 feet ahead contributes to a safer driving experience for everyone.
