This violation means you made a left turn or U-turn without yielding to oncoming traffic that was close enough to be a hazard. Essentially, you cut off another vehicle or forced them to brake or swerve because you turned in front of them.
A CVC 21801(a) ticket carries a fine between $238 and $350, plus 1 point on your DMV record. That point stays for 3 years and can increase your insurance rates by 15-25% annually, costing you hundreds of dollars beyond the ticket itself.
A CVC 21801(a) conviction adds 1 point to your record, which insurers typically view as a moderate-risk violation. Expect premium increases of 15-25% for 3 years, potentially costing $500-$1,500 more in insurance over that period.
Driver waits at a green light to turn left, sees a gap, but oncoming car is traveling faster than expected and must brake suddenly.
Ticket issued. Driver may argue misjudgment of speed, but officer witnessed the hazard created.
Driver turns left at an intersection with obstructed visibility due to a large truck blocking the view of oncoming traffic.
Strong defense case. Obstructed sightlines can demonstrate the driver could not reasonably see approaching vehicles.
Driver makes a left turn and oncoming vehicle runs a red light, nearly causing a collision.
Defensible. If the other driver violated traffic laws, the turning driver had the right to proceed.
Driver assumes oncoming car will stop at a yellow light and begins left turn, but oncoming car continues through.
Ticket likely upheld. Drivers cannot assume others will stop; you must yield to vehicles already in the intersection.
These are the defense arguments that appear most often in successful Trial by Written Declarations for this violation.
Sufficient gap in oncoming traffic
CVC 21801(a) requires yielding when turning left across oncoming traffic. If the gap in oncoming traffic was sufficient for a safe turn and no vehicle was hazardously close, the element of "failure to yield" may not be established. Provide a specific account of the gap you observed.
Oncoming driver's actions contributed
If an oncoming driver accelerated, changed lanes without warning, or otherwise acted unpredictably, this context is relevant to whether you exercised reasonable judgment.
⚠️ What NOT to Do
Optionally describe your situation — road conditions, time of day, officer position — and get a tailored document preparation overview.
If you can demonstrate the other vehicle was traveling significantly above the speed limit, this can be a valid defense. You're entitled to judge gaps based on reasonable speed expectations. Dashcam footage or witness testimony about the other car's speed would strengthen this argument.
Yes, somewhat. If you were already in the intersection waiting to turn and oncoming traffic had a duty to allow you to clear, this may help your case. However, the key issue is whether you created a hazard by turning when you did.
A green light does not give you the right of way for left turns. You must still yield to oncoming traffic going straight. Only a green arrow (protected left) gives you the right of way over oncoming vehicles.
Absolutely. The violation is about creating a hazard, not causing an accident. However, the lack of an accident can actually support your defense by arguing that no genuine hazard existed and the officer misjudged the situation.
Section (a) applies when you're facing a green light and must yield to oncoming traffic. Section (b) applies when you've already entered the intersection and are waiting — it requires other drivers to let you complete your turn. Both relate to left turns but address different situations.
Traffic School Option
Most drivers cited for CVC 21801(a) qualify for traffic school if they haven't attended in the past 18 months and don't hold a commercial license. Completing traffic school keeps the point off your public record and prevents insurance increases.
