California has almost 40 million residents, so traffic is seemingly everywhere. According to U.S. Census Bureau data, there are 31 million cars in California legally registered to be on the road—which is more than any other state.
Because of this, you shouldn’t be surprised that CA also has the most congested roadways in the country. To compound the traffic issue even further, the state is home to nine of the top 50 worst cities for traffic:
  • Los Angeles
  • San Francisco
  • San Jose
  • San Diego
  • Riverside
  • Sacramento
  • Fresno
  • Bakersfield
  • Oxnard/Thousand Oaks/Ventura
Due to the sheer number of other motorists, upping your car insurance coverage limits or adding collision or comprehensive insurance is a savvy move. But before you drop tons of money on a policy, use the Jerry app to shop around for the best rate.
