What is the minimum safe distance a driver should maintain when passing a bicycle?

Maintaining a minimum distance of three feet when passing a bicycle is essential for ensuring the safety of both the cyclist and the driver. This distance allows for adequate space to accommodate any sudden movements the cyclist might make, such as swerving to avoid an obstacle or in response to wind. Furthermore, it helps protect cyclists from being too close to the driver’s vehicle, which could lead to accidents or injuries, particularly in the event of a side mirror or tire coming too close to the bike.

In many jurisdictions, including Virginia, this three-foot rule is not just a recommendation; it's often mandated by law. This legal requirement underscores the importance of the driver’s responsibility to ensure safety for all road users, especially the more vulnerable ones, such as those on bicycles.
