What is a Bicycle Riding Against Traffic ticket?
This violation occurs when a cyclist rides their bicycle against the flow of traffic on a roadway. California law requires bicycles to travel in the same direction as cars, just like any other vehicle on the road.
The base fine is around $25, but with California's court fees and assessments, the total typically reaches $150-$200. While this violation carries zero DMV points and won't directly affect your auto insurance, it still creates a court record and costs money.
This bicycle violation carries zero DMV points and does not appear on your driving record, so it will not affect your auto insurance rates. However, if you have separate bicycle insurance, check whether citations could affect that coverage.

Frequently Asked Questions About Bicycle Riding Against Traffic
Why can't I ride against traffic to see oncoming cars?▼
While it may feel safer, studies show wrong-way cycling causes more accidents. Drivers don't expect traffic coming from the wrong direction, especially at intersections and driveways. California law requires cyclists to be predictable like other vehicles.
What is a contra-flow bike lane?▼
A contra-flow bike lane is a designated lane that allows cyclists to travel in the opposite direction of vehicle traffic, typically on one-way streets. These lanes have special markings and signage and are the only legal way to ride against traffic flow.
Does this ticket go on my driving record?▼
No, bicycle violations under CVC 21650.1 do not add points to your DMV driving record. However, the citation itself is a court record and must still be resolved by paying the fine or contesting it.
Can I get this ticket on a sidewalk?▼
No, this specific violation applies to roadways. However, riding on sidewalks has its own rules that vary by city — some prohibit it entirely, while others allow it with restrictions. Check your local ordinances.
What if I was avoiding a dangerous road hazard?▼
If debris, a pothole, parked vehicle, or other hazard made it temporarily unsafe to ride with traffic, this may be a valid defense. Document the hazard's location and nature as soon as possible after receiving the ticket.
