What is California Vehicle Code CVC 21658(a)?
Driving outside of designated lane boundaries
Common scenarios
- You briefly crossed the lane line to avoid a pothole but stayed safe and did not interfere with other drivers.
- The lane lines were worn out and hard to see because of rain or poor lighting, so you didn’t realize you were drifting.
- You signaled and moved into the next lane to pass a slow car, but the officer thought you were driving outside your lane without signaling.
Key facts
- Lane Lines Are Your Guide: Lane lines help keep cars in order. Crossing them without a good reason can be unsafe and is against the law.
- Safe Lane Changes Are Allowed: You can cross lane lines when you signal and change lanes safely. The ticket usually applies when you drift or swerve without signaling.
- Not All Tickets Are Fair: Sometimes officers make mistakes or road conditions cause confusion. You can explain your side and ask for a dismissal.
