What is the minimum passing space required between a vehicle and a bicyclist?

The minimum passing space required between a vehicle and a bicyclist is three feet. This distance is established to ensure the safety of bicyclists on the road. When a vehicle passes a cyclist, having this buffer zone helps to reduce the risk of collisions that may occur due to wind turbulence created by the vehicle or close encounters that could lead to accidents.

Having at least three feet of space allows cyclists to maintain a steady line of travel and feel secure while riding on the roadway. This regulation is particularly important as it supports the safety of vulnerable road users like cyclists. In many jurisdictions, including North Dakota, this guideline helps encourage safer driving habits and cultivates a more amicable sharing of the road between motorists and cyclists.

A smaller passing distance, such as one or two feet, could create a hazardous situation for the cyclist by increasing the likelihood of forced movements or collisions if the vehicle strays slightly from its path. A four-foot requirement, while potentially safer, is not the established minimum and may be impractical in certain road conditions where space is limited. Hence, three feet is recognized as the effective and appropriate minimum distance.
