Speed Safety System
About the AB645 Speed Safety System pilot program
With the passage of AB 645, Los Angeles and five other California Municipalities have the opportunity to introduce Speed Safety Systems as a Pilot Program to address speeding and enhance safety on our roads. Speed safety systems are a proven measure to combat excessive speeding1. According to FHWA, similar programs have reduced injury crashes in other cities by nearly 50%.
Why is Los Angeles installing speed safety systems?
Speed is a central factor in traffic collisions that result in fatalities or 
severe injuries. In Los Angeles, 1 in 5 fatal collisions between 2017 and 2021 involved unsafe speeding.
Speed Safety Systems reduce the amount of drivers greatly exceeding the posted speed limit and the likelihood of a crash that results in a fatality or serious injury by 19%. Cities with similar systems cut speeding of 10 mph or more by 62%. The graph below shows the correlation between speeding and death2.
Speeding is dangerous because:
- Crashes at higher speeds are more forceful
- Drivers traveling at higher speeds have a narrower field of vision
- Drivers traveling at higher speeds take longer to react to unexpected situations
- Vehicles traveling at higher speeds have longer braking distances
336 people died in crashes on Los Angeles streets in 2023, and more than half of them were pedestrians. This pilot program is intended to save lives.
Where will the speed safety systems be located?
AB 645 allows up to 125 speed safety systems to be deployed in the City of Los Angeles. The law requires these locations to be geographically and socioeconomically diverse. The City will weigh a variety of factors including community input and historic collision data when determining where to place these systems.
Once installed, the speed safety systems will be easy to see. There will be signs stating “Photo Enforced” clearly placed on the roadway in advance of each location. Additionally, a list of the locations will be posted on this website.
How will the pilot program impact me?
Speed safety systems are designed to discourage unsafe speeding. They work by capturing the license plate numbers of vehicles exceeding the posted speed limit and mailing a ticket to the owner of the speeding vehicle.
The speed thresholds and associated penalties are established by AB 645 as follows:
If you exceed the speed limit by… | Your fine will be… |
11-15 mph | $50 |
15-25 mph | $100 |
26-99 mph | $200 |
100+mph | $500 |
After systems are installed, warning notices will be issued for the first 60 calendar days. Warnings will also be issued for any first violation for traveling 11 to 15 mph over the posted speed limit.
Payment plans and fine reductions are available for low-income households. In addition, qualifying low-income recipients of speeding violations are eligible to perform community service in lieu of paying fines.
