Rules of the road
Lesson 3 · Sharing the road

How much space should you give a cyclist when passing?

Short answer

At least 3 feet in most states, and more at higher speeds. Wait for a safe gap in oncoming traffic before you pass.

Watch it play out

How to do it

  1. Slow down and stay back until you can see a clear gap.
  2. Move left so there are at least 3 feet between your car and the bike.
  3. Pass, then check your mirror before moving back.
  4. Never honk to make a cyclist move.

Why the rule works this way

Bikes can wobble to avoid potholes and debris, and a close pass can knock a rider over. Extra space is a buffer for both of you.

Common mistakes

  • Squeezing past in the same lane.
  • Cutting back in right after passing.
State differencesAt least 35 states and DC set a 3-foot minimum. Pennsylvania and New Jersey require 4 feet, and some states require a full lane change on multi-lane roads.
In VirginiaPass at least 3 feet away. If the lane is too narrow for that, change lanes. You may cross a double yellow line to pass a cyclist when it is safe. See all Virginia rules
