Is San Dimas 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 Lone Hill Ave & Kent St (5). 35% were side-impact crashes at junctions (drivers pulling out or turning across). 10% were sideswipes (close passes, right hooks, car doors).
