Speed camera on Guerrero St
Between 19th St and 20th St · District 8
“Guerrero St from 19th St to 20th St — Issuing Violations” — SFMTA ↗
What this camera means for you
This is one of 33 speed safety systems SFMTA operates under California AB 645. It photographs the rear licence plate of vehicles travelling 11 mph or more over the posted limit — on this street, that means 36 mph or above.
Citations are civil penalties, not moving violations. They do not add points to your driving record and are not reported to your insurer as a moving violation. Fines start at $50, and low-income drivers can request reductions or payment plans.
When cameras are first activated on a street, California AB 645 requires a 60-day warning period during which only warnings are issued.
Why this location was chosen
SFMTA publishes the data behind each site selection. For this location:
The 85th percentile speed is the speed at or below which 85% of drivers travel. Here it is 29 mph on a road posted at 25 mph.
Location
SFMTA publishes a camera location rather than an enforcement zone, so this is a point on the block, not the exact pole position. See it on the map.
Published location: 37.75942, -122.42360
