California’s daylighting law, known as AB 413, is changing how drivers park near intersections and crosswalks. The law is meant to make streets safer by keeping corners clear, so people walking, biking or driving can see each other before entering the same space.
If you ride a bike in Southern California, this law matters more than it may seem. A parked car near a corner can hide you from a turning driver. It can also block your view of traffic, forcing you to move forward without knowing what is coming.
Clear corners can save lives
AB 413 generally prohibits parking within 20 feet of a marked or unmarked crosswalk. Where there is a curb extension, that distance is usually 15 feet. The goal is to open up sightlines before someone reaches the intersection.
For cyclists, better visibility can reduce common crash risks, such as:
- Drivers turning right without seeing a bike in the bike lane
- Cars pulling out from side streets with limited visibility
- Riders entering intersections without a clear view of traffic
- Pedestrians stepping out from behind parked vehicles
This law does not remove every danger from the road. Drivers still need to check mirrors, yield when required and watch for cyclists. Cyclists also need to stay alert, follow traffic rules and use lights or reflective gear when visibility is poor.
However, daylighting can have a huge impact, as many serious bike crashes occur at intersections. By keeping parked cars away from corners, AB 413 gives everyone more time to notice danger and react.
If you are hurt in a bicycle crash near an intersection, the parking layout, visibility, traffic signs and driver behavior may all matter. Knowing how AB 413 applies can be part of that review, which is why informed legal support may help you better understand your options.
