Will my long commute raise my insurance rate in Diablo?
It can, since annual mileage is one of the top factors insurers must weigh under Prop 103. Giving an accurate mileage figure and comparing carriers helps you find a fair price.
Is car theft something Diablo drivers should worry about?
The countywide rate is about 3.4 thefts per thousand people, slightly above the state's 3.2. Comprehensive coverage pays for theft, fire, flood and vandalism, while liability-only does not cover your own car.
