Los Angeles applies a 25 mph prima facie speed limit on most local and residential streets under California law, rising to 30 to 45 mph on major boulevards and 65 mph on freeways. AB 43 now lets the city lower limits for safety.

About speed limits in Los Angeles
California sets a statewide prima facie speed limit of 25 mph on any street in a business or residence district that is not a state highway, and Los Angeles follows that default on the vast majority of its local and residential streets. A prima facie limit is the speed presumed safe when no engineering survey has posted something different, so many neighborhood streets carry 25 mph even without a visible sign. Larger arterials and boulevards are typically posted between 30 and 45 mph based on traffic-and-engineering surveys required under the California Vehicle Code.
Assembly Bill 43, which took effect on January 1, 2022, changed how Los Angeles sets speed limits by giving the city more authority to lower them for safety. Under AB 43, cities can set 20 to 25 mph limits in business activity districts and drop limits up to 5 mph below an engineer's recommendation on designated safety corridors or near where vulnerable road users gather. LADOT began lowering speeds on selected corridors starting in 2022, reversing years of state rules that had forced limits upward toward the 85th-percentile speed of traffic.
Residential streets default to 25 mph, while school zones drop to 25 mph when children are present and lower where posted. Under AB 645, Los Angeles is one of six California pilot cities authorized to install automated speed safety cameras, with plans for roughly 125 locations concentrated near schools, senior centers, and high-injury corridors. The pilot uses warning notices before citations and issues tickets by mail rather than adding DMV points.
Freeways through Los Angeles, including I-5, I-10, I-405, and US-101, are generally posted at 65 mph, the maximum on most urban California freeways, though congestion keeps real-world speeds far lower. A handful of segments allow 70 mph outside the urban core. Unlike some cities, Los Angeles has historically had no fixed speed cameras, so freeway and street enforcement has relied on CHP and LAPD officers until the AB 645 pilot begins.
Enforcement
Los Angeles street and freeway enforcement has long been handled by LAPD and California Highway Patrol officers rather than cameras. Under the AB 645 pilot, the city is deploying automated speed safety cameras near schools and high-injury corridors, its first use of photo speed enforcement.
Tolerance
Officers exercise discretion and rarely stop drivers a few mph over, but California has no legal buffer. The AB 645 speed cameras only capture violations at 11 mph or more over the posted limit.
Speeding fines in Los Angeles
A typical California officer-issued ticket runs about 274 dollars for 1 to 15 mph over once state penalty assessments and court fees multiply the small base fine, rising to roughly 438 dollars for 16 to 25 mph over. AB 645 camera fines start at 50 dollars for 11 mph over and scale to 100, 200, and 500 dollars, with reductions for low-income drivers.
