Motorcycle Lane Filtering & Passing

Concerning authorization for a two-wheeled motorcycle to overtake another motor vehicle in the same lane.
2024 Regular Session
Transportation & Motor Vehicles
Bill Summary

The bill authorizes a 2-wheeled motorcycle to overtake or pass another motor vehicle in the same lane if:

  • The other motor vehicle is stopped; or moving in the same direction of travel as the motorcycle;
  • The road has lanes wide enough to pass safely;
  • The motorcycle is moving at 20 15 miles per hour or less; and
  • Conditions permit prudent operation of the motorcycle while overtaking or passing.

A motorcycle rider overtaking or passing under the bill must not overtake or pass:

  • On the right shoulder;
  • To the right of a vehicle in the farthest right-hand lane if the highway is not limited access; or
  • In a lane of traffic moving in the opposite direction.

The authorization to overtake or pass is repealed, effective September 1, 2027. Before the repeal, the Colorado department of transportation will collect safety data on the bill and issue a report to the general assembly.
