What is California Vehicle Code CVC 25103?
Violation of California Vehicle Code Section 25103
Common scenarios
- You changed lanes on a busy highway but forgot to turn on your signal because you were focused on traffic around you.
- You made a quick right turn in a parking lot without signaling because there were no other cars nearby.
- Your turn signal bulb was burned out, so even though you flipped the switch, no blinking light showed.
Key facts
- Signal at least 100 feet before turning: This gives other drivers enough time to notice your intention and react safely.
- Always use your turn signal when changing lanes: Even if the road looks empty, signaling is required by law.
- Failure to signal can lead to a fine and points on your record: This can affect your insurance rates and driving privileges.
