This violation occurs when you pass another vehicle in an unsafe location, specifically on a curve or hill where you cannot see far enough ahead to pass safely. California law prohibits overtaking when your view of oncoming traffic is blocked by the road's grade or curvature.
A CVC 21751 ticket costs between $238 and $490 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, potentially costing you hundreds of extra dollars.
A CVC 21751 conviction typically raises insurance premiums by 15-25% for three years. For an average California driver, this can mean $300-$600 in additional insurance costs over that period, on top of the original fine.
A driver passes a slow-moving truck while going uphill, unable to see over the crest of the hill ahead.
Ticket issued because the driver couldn't see if oncoming traffic was approaching from beyond the hill.
A motorist attempts to pass a vehicle on a winding mountain road where the curve blocks visibility of oncoming lanes.
Citation given for passing where the driver couldn't see at least 200 feet ahead in the oncoming lane.
A driver passes a cyclist on a straight section of road with clear visibility for 500 feet ahead.
No violation because there was adequate visibility to complete the pass safely.
These are the defense arguments that appear most often in successful Trial by Written Declarations for this violation.
Sufficient sight distance was available
CVC 21751 prohibits overtaking when there is not sufficient clearance ahead. If sight distance was adequate and no oncoming traffic was within the danger zone, challenge the factual determination.
⚠️ What NOT to Do
Optionally describe your situation — road conditions, time of day, officer position — and get a tailored document preparation overview.
A grade refers to any hill or incline that limits your ability to see the road ahead. This includes both going uphill where the crest blocks your view and coming down where the slope may obscure approaching vehicles.
California law requires you to be able to see at least 200 feet ahead in the oncoming lane before passing. If a hill or curve prevents this visibility, passing is prohibited regardless of whether traffic is actually present.
Yes, but focus on proving you had adequate visibility, not that the road was empty. The violation is about obstructed sight distance, not whether oncoming traffic was actually present at that moment.
Yes. CVC 21751 specifically addresses passing on hills and curves with limited visibility. Passing zone violations (marked with double yellow lines) fall under CVC 21460 and are separate offenses.
The speed of the vehicle you're passing doesn't change the visibility requirements. However, if visibility was actually adequate to safely pass, you can argue that point regardless of what type of vehicle you passed.
Traffic School Option
Most drivers cited for CVC 21751 qualify 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.
