Can you pass a cyclist on the road in Missouri?
It’s legal for drivers to pass cyclists on the road in Missouri, just like it’s legal for one car to pass another. Drivers should not pull out in front of a moving bicyclist, cut a bicyclist off or pass a bicyclist unsafely.
Missouri statute 304.678 says, “The operator of a motor vehicle overtaking a bicycle proceeding in the same direction on the roadway shall leave a safe distance, when passing the bicycle, and shall maintain clearance until safely past the overtaken bicycle.”
Chapter Seven in the Missouri Driver’s Guide says to give cyclists a full lane width when you are passing them and not to try to squeeze past them on narrow roads. Bicycles are also required to be driven close to the right side of the roadway as safely as possible.
Are there penalties for illegally passing a cyclist in Missouri?
With some exceptions, you should only use the left lane to pass drivers in the right lane.
Missouri statute 304.015 says vehicles should drive on the right half of a roadway except when:
- Passing another vehicle
- Making a left turn
- Right lanes are closed for construction
- Driving on a one-way street
The rule applies to drivers on all public roads that are large enough, including highways of three or more lanes. There are other exceptions, including when officials are directing traffic or if an emergency vehicle needs to get by.
Since cyclists are considered vehicle operators are the roads in Missouri, you can be penalized for passing one illegally, just like you would if you illegally passed by a car.
State statute 304.016 says no vehicle shall be driven on the left side of the road under these conditions:
When approaching the crest of a grade or upon a curve of the highway where the driver’s view is obstructed within such distance that would create a hazard in the event another vehicle may approach from the other side
When the view is obstructed when the driver is within 100 feet of any bridge, viaduct, tunnel or at any intersection or railroad grade crossing.
Illegally passing a bicycle is a class C misdemeanor, which can carry a fine of up to $750 or up to 15 days in jail.
