What is the minimum distance to signal before turning?

Answer: C — At least 100 feet

The minimum distance to signal before turning is at least 100 feet. This requirement is in place to ensure that other drivers and pedestrians have adequate notice of your intentions to turn, which helps improve safety on the road. By signaling at least 100 feet in advance, you provide enough time for others to react appropriately and adjust their own driving behavior. This practice is crucial, especially in busy or high-traffic areas where sudden movements can lead to accidents. Early signaling promotes better communication among road users and contributes to a safer driving environment.
