What is the legal requirement when signaling a turn in terms of distance?

The legal requirement for signaling a turn is that signals must be given at least 100 feet before making the turn. This guideline is in place to ensure that other road users, including drivers, pedestrians, and cyclists, have adequate notice of your intentions to turn. By signaling in advance, you help to promote safety and reduce the chances of accidents by giving others time to react to your maneuver.

This requirement helps maintain clear communication on the road, allowing other drivers to anticipate your actions and adjust their driving accordingly. It creates a more predictable driving environment, which is essential for safe navigation in traffic.

When evaluating the other choices, it’s clear that signaling only at intersections does not provide sufficient warning for turns occurring before reaching such points. Additionally, indicating that signals are unnecessary if the road is clear undermines the safety principle of communicating intentions regardless of the presence of other vehicles. Finally, restricting signals to situations when another vehicle is present does not account for pedestrians or other road users who may be affected by a driver's turn. Signaling serves a broader purpose than just alerting adjacent vehicles, making the specified advance signaling distance of 100 feet crucial for all road users.
