What is a Failure to Yield at Flashing Yellow Signal ticket?
This ticket means you failed to yield the right-of-way to other vehicles or pedestrians when approaching an intersection with a flashing yellow signal. A flashing yellow light is a warning to slow down and proceed with caution, yielding to any cross traffic or pedestrians who have the right-of-way.
This violation carries a fine between $238 and $350, adds 1 point to your DMV record, and can increase your insurance premiums by 15-20% for three years. One point may not seem significant, but accumulating points can lead to license suspension and substantially higher long-term costs.
One point typically increases insurance premiums by 15-20% for three years. For an average California driver paying $2,000 annually, this could mean $900-$1,200 in additional premiums over that period—far exceeding the ticket fine itself.

How Drivers Get This Ticket
A driver approaches a flashing yellow signal at an intersection and proceeds through without slowing, nearly hitting a pedestrian in the crosswalk.
Cited for CVC 21457(b) for failing to yield to the pedestrian who had the right-of-way.
A motorist sees a flashing yellow light and assumes they have priority, pulling into the intersection and cutting off a vehicle on the cross street that had already entered.
Ticketed for failure to yield because the other vehicle was already in the intersection.
A driver stops completely at a flashing yellow signal even though no traffic is present, then proceeds carefully.
No violation—while stopping isn't required at flashing yellow, yielding and proceeding cautiously satisfies the law.
Late at night, a driver approaches a flashing yellow signal with a malfunctioning sensor that recently changed from solid green.
Potential defense exists if the signal malfunction created confusion about right-of-way.

Frequently Asked Questions About Failure to Yield at Flashing Yellow Signal
What's the difference between a flashing yellow and flashing red signal?▼
A flashing yellow means slow down, proceed with caution, and yield to any traffic or pedestrians with the right-of-way. A flashing red requires a complete stop before proceeding, similar to a stop sign.
Do I have to stop completely at a flashing yellow light?▼
No, a complete stop is not required at a flashing yellow signal. You must slow down, exercise caution, and yield to any vehicles or pedestrians who have the right-of-way before proceeding.
How does the officer determine I failed to yield?▼
The officer must observe that another vehicle or pedestrian had the right-of-way and that your failure to yield created a conflict or near-collision. Simply proceeding through a flashing yellow without another party present is not a violation.
Can I fight this ticket if no accident occurred?▼
Yes, you can contest the ticket regardless of whether an accident happened. You can argue there was no one to yield to, the signal was obscured, or the officer misperceived the situation.
Will this ticket affect my commercial driver's license?▼
Yes, this violation will appear on your commercial driving record and counts toward the points that could affect your CDL. Commercial drivers are generally not eligible for traffic school to mask points.
Traffic School Option
Most drivers are eligible 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, though the conviction remains on your court record.
