California Road Map Overview
Major highways in California have a maximum speed of 65 mph (104 kmph). Heavy traffic in California should be a concern, which occurs in cities weekdays around the hours of 8am and 5pm. It's not too difficult to avoid traffic times when leaving a city, but incorrectly timing your entrance to a city after a long California road trip can cost you several additional hours in traffic.
EXAMPLE: When embarking on a California road trip from north to south, don't randomly decide a time of departure. Instead, consider what the L.A. traffic will be like at arrival and choose a time frame to avoid L.A. traffic times. This should determine your departure time. Failure to do so will result in additional hours of heavy L.A. traffic.
Google Maps offers a great California traffic map for all cities & highways.
