Is Mill Valley 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.

The most were at Sycamore Ave & Camino Alto (10). 29% were side-impact crashes at junctions (drivers pulling out or turning across). 16% were sideswipes (close passes, right hooks, car doors).
