This violation is issued when you're caught driving on the left side of the road when you should have been on the right. California law requires vehicles to stay on the right half of the roadway unless you're passing another vehicle, avoiding an obstruction, or following specific road markings.
A CVC 21650(a) ticket costs approximately $238–$350 and adds 1 point to your DMV record. That point stays on your record for 3 years and can increase your auto insurance rates by 15-25% annually.
One point on your record for this violation can increase insurance premiums by 15-25% for about 3 years. Attending traffic school or successfully contesting the ticket can prevent this increase.
Upon all highways, a vehicle shall be driven upon the right half of the roadway, except as follows: when overtaking and passing another vehicle, when the right half is closed to traffic, or on a roadway divided into three marked lanes.
A driver drifts into the oncoming lane while distracted by their phone on a two-lane rural road.
Likely valid ticket — distraction is not a legal exception for driving on the wrong side.
A driver moves left to avoid a large pothole or debris in the right lane.
May have valid defense — avoiding hazards or obstructions is a recognized exception under the law.
A driver briefly crosses the center line while passing a slower vehicle on a road with broken yellow lines.
Valid defense — lawful passing maneuvers are expressly permitted under CVC 21650(a).
A driver takes a wide turn at an intersection and momentarily enters the wrong side of the cross street.
Likely valid ticket — turning does not qualify as an exception to the right-side requirement.
These are the defense arguments that appear most often in successful Trial by Written Declarations for this violation.
Exception: passing, turning, or hazard
CVC 21650(a) requires driving on the right side of the roadway. Exceptions include: when passing another vehicle, making a left turn, when the right side is blocked, or when on a one-way street. If any exception applied, document it.
One-way street
On a one-way street, you may drive in any designated lane. Verify the road configuration.
⚠️ What NOT to Do
Optionally describe your situation — road conditions, time of day, officer position — and get a tailored document preparation overview.
Not necessarily. The law allows crossing into the left side for passing, avoiding obstructions, or when road conditions require it. A brief, momentary crossing for a valid reason may be defensible.
Yes. Avoiding road hazards is a recognized exception under CVC 21650(a). Document the hazard with photos if possible and explain the circumstances in your defense.
No, CVC 21650(a) is a standard moving violation, not reckless driving. However, if combined with other dangerous behavior, additional charges could potentially apply.
Unclear road markings can be a valid defense point. If you couldn't reasonably determine the roadway's center, document this with photos showing the road conditions.
Traffic infractions like CVC 21650(a) typically don't appear on criminal background checks. However, it will appear on your DMV driving record, which employers may check for driving-related positions.
Traffic School Option
Most drivers cited for CVC 21650(a) qualify for traffic school if they haven't attended in the past 18 months and hold a valid non-commercial license. Completing traffic school masks the point from your insurance company.
