Under California left turn law, a driver turning left must yield the right-of-way to every oncoming vehicle close enough to be a hazard, approach the turn from the leftmost lane going their direction, and signal continuously for at least the last 100 feet before turning.1California Legislative Information. California Vehicle Code VEH 21801 – Right-of-Way Left Turn Breaking any of those rules is an infraction that costs roughly $234 after assessments and adds one point to your driving record.2California Courts. Uniform Bail and Penalty Schedules 2026
Yield to Oncoming Traffic
This is the rule that drives everything else. When you turn left on any California roadway, whether into a cross street, a driveway, or a parking lot, you must yield to every vehicle coming from the opposite direction that is close enough to pose a hazard at any point during your turn. You keep yielding until you can complete the turn safely.1California Legislative Information. California Vehicle Code VEH 21801 – Right-of-Way Left Turn
There is no fixed distance that defines “close enough to be a hazard.” It depends on how fast the oncoming car is traveling and how long your turn will take. When in doubt, wait for the next gap.
Green Light Versus Green Arrow
A circular green signal lets you turn left, but it does not clear the way for you. You still yield to oncoming traffic and to pedestrians lawfully in the intersection or crosswalk.3California Legislative Information. California Code VEH 21451 – Circular Green Signal A green arrow is a protected turn: oncoming traffic has a red light, so you only need to watch for pedestrians while you turn.
Stop Signs and Uncontrolled Intersections
The same yield rule governs intersections without signals. If you are stopped at a stop sign waiting to turn left, you wait for every approaching vehicle close enough to make the turn risky, even if you reached the intersection first.
Get Into the Left Lane Before You Turn
You have to approach a left turn as close as practicable to the left edge of the farthest left lane available for traffic going your direction.4California Legislative Information. California Code VEH 22100 – Right and Left Turns Translation: get into the leftmost lane before the intersection, and don’t drift across lanes while you’re turning.
You also cannot start the physical turn before you enter the intersection. Cutting the corner early puts you into the path of cars sitting in the opposing left-turn lane. Once inside the intersection, finish the turn and exit into any lane lawfully open to traffic going your new direction.
One narrow exception covers three-lane roads. If you are on a highway with three marked lanes going your direction and it dead-ends into a two-way road, the driver in the middle lane may also turn left into any legally available lane.4California Legislative Information. California Code VEH 22100 – Right and Left Turns
Signal at Least 100 Feet Before the Turn
You cannot turn from a straight course until the movement can be made safely, and you must signal first whenever another vehicle could be affected.5Justia. California Code VEH 22107 – Turning and Required Signals Your signal, whether a turn indicator or a hand signal, has to run continuously for the last 100 feet before the turn.6California Legislative Information. California Code VEH 22108 – Signal Duration
At typical city speeds of 25 to 35 mph, 100 feet goes by in roughly two seconds, so turn the signal on well before you touch the brake. Signaling early also protects you if a following driver rear-ends you while you’re slowing down.
Using a Two-Way Left-Turn Lane
Busier roads often have a center lane marked with parallel double yellow lines, the inner line dashed and the outer line solid on each side. That is a two-way left-turn lane. Drivers heading in either direction can use it to stage a left turn into a side street, driveway, or parking lot.7California Legislative Information. California Code VEH 21460.5 – Two-Way Left-Turn Lanes
Two limits matter. You cannot travel in the center lane for more than 200 feet while preparing to turn, so you can’t hop in a block early and ride it like a regular travel lane. And when a two-way left-turn lane exists on the road, you have to use it: making the left turn from any other lane is illegal.
When You Can Turn Left on Red
California allows one specific left turn on red. After coming to a complete stop at a steady circular red, you may turn left from a one-way street onto another one-way street, as long as no sign prohibits it.8California Legislative Information. California Code VEH 21453 – Circular Red or Red Arrow Before you go, yield to pedestrians in the crosswalk and to any approaching vehicle close enough to be an immediate hazard.
That is the only legal left on red. You cannot do it from a two-way street, you cannot do it on a red arrow, and a posted “No Turn on Red” sign ends the exception even on a qualifying one-way-to-one-way intersection.
Local No-Turn Signs Override the Default
Cities and counties can restrict turns at specific intersections with posted signs or traffic control devices. “No Left Turn” and “Left Turn Only” signs override whatever the Vehicle Code would otherwise permit, and some urban restrictions apply only during certain hours for rush-hour management. The posted sign always controls.
What a Ticket Costs
Turning violations are infractions. The base fine for most of them is just $35, but after California’s mandatory penalty assessments, surcharges, and court fees pile on, the total lands around $234.2California Courts. Uniform Bail and Penalty Schedules 2026 Some counties run higher.
Most turning infractions also put one point on your DMV record. Points stay for three years and can trigger a license suspension if you accumulate four points in 12 months, six in 24 months, or eight in 36 months. They also tend to raise your auto insurance premiums.
Traffic School
For a one-point turning violation, you can usually ask the court for permission to attend traffic school. Completing the course keeps the point off your public driving record, so your insurer never sees it. California limits this to once every 18 months, and the court can deny it based on your record. You still pay the full fine plus a court administrative fee.
Who’s at Fault in a Left-Turn Crash
Because the law puts the yield burden on the left-turning driver, insurance adjusters and courts start with a strong presumption that the turning driver caused the collision. The presumption is not absolute. The oncoming driver may have been speeding, running a red light, or otherwise distracted, but overcoming it takes real evidence.
California uses pure comparative negligence, so fault can be split between both drivers by percentage. If you are found 70% at fault for a left-turn collision, you can still recover 30% of your damages from the other driver, and the other driver can also recover from you in proportion to your share. Dashcam footage, traffic camera recordings, and witness statements often decide whether the split is 100/0 or something more balanced.
