Diamond Bar is a suburban community with lots of residential streets, plus commuting routes that can get crowded during peak hours. Cyclists often share the road with drivers who are:
- Turning at busy intersections while checking traffic flow
- Traveling at speeds that make sudden hazards harder to avoid
- Driving during low-visibility conditions (dusk, glare, overcast)
- Passing cyclists where there’s limited room or inconsistent lane markings
Even when you feel strongly that you’re not at fault, insurance adjusters may argue you contributed—such as by lane position, speed, or whether you had adequate visibility.
That’s why the early focus should be: what can be proven, not what feels obvious.
