Is Brentwood safe to ride a motorcycle?
This page covers traffic crashes, not crime.

The most were at Oak St & 2nd St (4). 26% involved no other vehicle, usually running wide or losing grip. 15% involved a car turning left across the rider.

Reported motorcycle crashes, 2021–2026. The officer names one party and one Vehicle Code section as the main cause of each crash; these are the crashes where that party was a driver.
