Arizona Driving Permit Written Practice Test

How much clearance should you allow when sharing a lane with a bicycle?

1. 1 foot

2. 3 feet

3. 5 feet

4. 10 feet

The correct answer is: 3 feet

Allowing at least 3 feet of clearance when sharing a lane with a bicycle is important for the safety of both the cyclist and the motorist. This distance provides enough space for the cyclist to maintain their balance and for the driver to avoid any potential collisions, particularly in situations where the bicycle may sway or if the cyclist encounters a hazard. Additionally, having 3 feet of clearance is often regarded as a standard recommendation in many states to ensure safety on the road. While other distances such as 1 foot, 5 feet, or 10 feet may be proposed in different contexts, they do not align with the commonly accepted safety guidelines for adequate space when passing or sharing a lane with cyclists. The 3-foot rule strikes a practical balance, ensuring both parties can navigate safely without feeling cramped or threatened.
