What is the minimum visibility distance for turn signals in normal daylight?

The minimum visibility distance for turn signals in normal daylight is set at 300 feet. This distance is established to ensure that other drivers on the road have adequate time to see your signaling intentions and respond appropriately. When you activate your turn signal well in advance of a turn or lane change—300 feet before making the maneuver—it provides sufficient notice to surrounding traffic, contributing to overall safety on the roadway. This distance helps prevent accidents by allowing other drivers to adjust their speed or position in anticipation of your movement. It's crucial for maintaining clear communication between drivers, especially in busy traffic conditions.
