According to Maryland law, a driver must leave at least 3 feet of space when passing a cyclist.

What the law actually says

Maryland’s Transportation Code requires drivers overtaking a bicycle to pass at a distance of not less than 3 feet and in a way that does not interfere with the cyclist’s safe operation.

This rule applies when a motor vehicle passes a bicycle, e-bike, EPAMD, or motor scooter being ridden on the roadway.

Practical meaning on the road

  • Slow down and only pass when you can give at least 3 feet of lateral clearance.
  • Do not “squeeze by” in the same lane if it would bring you closer than 3 feet.
  • After passing, check your mirror to be sure you are clear before moving back over.

Many safety materials in Maryland also remind drivers that 3 feet is a minimum , and more space is safer at higher speeds, in bad weather, on narrow roads, or if the cyclist might need to dodge potholes or debris.

In simple terms: if you can’t safely give a cyclist at least 3 feet, wait and pass later.
