CVC 21660 requires drivers to yield the right-of-way when driving on a single-lane road and meeting oncoming traffic. If there isn't enough room for both vehicles to pass safely, the driver going uphill generally has the right-of-way, and the downhill driver must yield by backing up or pulling over.
A conviction results in a fine between $238 and $350, plus 1 point on your DMV record. That point stays on your record for 3 years and can increase your insurance rates by 15-25% annually, potentially costing you hundreds of dollars over time.
One point on your record typically increases insurance premiums by 15-25% for three years. For most drivers, this means paying an extra $300-$600 or more in insurance costs, making it worthwhile to fight the ticket or attend traffic school.
You're driving down a narrow mountain road and meet a car coming uphill. Neither can pass, but you refuse to back up to a wider spot.
Citable under CVC 21660 because the uphill driver has the right-of-way on grades.
On a single-lane road, you encounter an oncoming vehicle. A turnout exists on your right side, but you stop and wait for the other driver to move.
Potentially citable because you failed to use the available turnout on your side.
You're driving uphill on a narrow road and an oncoming downhill driver refuses to yield. You honk and eventually both squeeze past.
You likely wouldn't be cited since the uphill vehicle has the right-of-way under this code.
Both you and an oncoming driver reach a narrow bridge simultaneously. You proceed forward instead of yielding to the vehicle that arrived first.
Citable for failing to yield when there was insufficient width for both vehicles.
These are the defense arguments that appear most often in successful Trial by Written Declarations for this violation.
You yielded as required
CVC 21660 governs merging when two lanes of traffic must join. Challenge whether the merge was handled safely — did you signal, adjust speed, and yield where required by the lane markings?
⚠️ What NOT to Do
Optionally describe your situation — road conditions, time of day, officer position — and get a tailored document preparation overview.
Under CVC 21660, the vehicle traveling uphill has the right-of-way on grades. The downhill driver must yield by backing up to a wider spot or pulling over to let the uphill vehicle pass.
The law requires yielding when it's practical and safe. If no turnout, shoulder, or safe area exists on your side of the road, this could be a valid defense to the citation.
No, CVC 21660 specifically applies to roads too narrow for two vehicles to pass each other safely. On standard two-lane roads with adequate width, normal passing rules apply.
Possibly. If the officer cited both drivers, it suggests the situation was unclear. You can argue that if both parties were found at fault, reasonable doubt exists about who was required to yield.
Simply stopping may not satisfy the requirement. Yielding under CVC 21660 may require you to back up to a turnout or pull as far right as possible so the other vehicle can pass safely.
Traffic School Option
Most drivers cited for CVC 21660 are eligible for traffic school if they haven't attended in the past 18 months. Completing traffic school keeps the point off your public driving record and prevents insurance increases.
