What is the minimum safe passing distance when passing a vulnerable road user?

The minimum safe passing distance when passing a vulnerable road user, such as a pedestrian, bicyclist, or motorcyclist, is established to ensure the safety of individuals who may be more susceptible to injury in the event of a collision. A distance of four feet is considered necessary to provide an adequate buffer between the vehicle and the vulnerable road user. This space allows for some lateral movement by the user, especially in the case of cyclists, who may swerve or stabilize themselves in response to environmental factors.

Ensuring a four-foot buffer helps to minimize the risk of accidents while promoting respect for the safety of all road users. It’s a regulatory measure that also reinforces the importance of awareness and caution when driving near individuals who may not be protected by the same structural safety features that vehicles possess.
