Where they cluster
All 9 spots, explainedIs Brentwood safe to ride a bike?
This page covers traffic crashes, not crime. We don't rate cities as safe or unsafe: crash counts can't say how risky a street is, and busy streets have more crashes partly because more people use them. What the records show: 86 bike crashes were reported in Brentwood from 2021–2026, 11 of them serious or fatal. The most were at Sycamore Ave & Brentwood Blvd (6). 34% were side-impact crashes at junctions (drivers pulling out or turning across). 17% were sideswipes (close passes, right hooks, car doors).

Reported bike 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. It is the officer's reading at the scene, not a court's finding, and many reports name the person on foot or on a bike instead, which we don't list.
