    What is California Vehicle Code CVC 25100?

    Operating vehicle without required turn signals or signal devices

    Common scenarios

    • You changed lanes on a busy street but forgot to signal because you thought it was a quick move.
    • Your turn signal bulb was burned out, and you didn’t realize it before the stop.
    • You made a right turn on a quiet road and didn’t signal because there were no other cars around.

    Key facts

    • Turn Signals Are Required by Law: California law (CVC 25100) says you must signal before turning or changing lanes to warn other drivers.
    • Signal at Least 100 Feet Before Your Turn: You need to start signaling early enough so others have time to react safely.
    • Not Signaling Can Lead to Fines and Points: If you don’t signal, you risk a ticket, fines, and points on your license, which can raise insurance costs.

    What is CVC 25100?

    This law says you must use your turn signals when turning or changing lanes. Turn signals help other drivers know what you're about to do. If you don’t use them, it can cause accidents or confusion.

    Why did I get this ticket?

    You might have been stopped because an officer saw you turn or change lanes without signaling. Even if you thought it was quick or safe, the law requires a signal every time.

    What does the law require?

    • Use your turn signal at least 100 feet before turning or changing lanes.
    • Signal clearly so other drivers can see or hear it.
    • This applies to all vehicles on public roads.

    What happens if I don’t signal?

    Frequently asked questions about CVC 25100

    Do I have to signal if no one is around?

    Yes. The law requires signaling every time you turn or change lanes, even if the road seems empty.

    What if my turn signal wasn’t working?

    You should fix it as soon as possible. If you got a ticket, you might explain this in court, but it’s your responsibility to keep signals working.

    Can I use hand signals instead of blinkers?

    Hand signals are allowed if your vehicle doesn’t have turn signals, like on a bike or older car, but most cars must use the built-in signals.

    How far before the turn do I need to signal?

    At least 100 feet before you turn or change lanes, so other drivers have time to notice.

    Will this ticket add points to my driving record?

    Yes, failure to signal usually adds one point, which can affect your insurance rates.
