You are driving on a freeway posted for 65 MPH. The traffic is traveling at 70 MPH. You may legally drive:

70 MPH or faster to keep up with the speed of traffic.
Between 65 MPH and 70 MPH.
No faster than 65 MPH.
Explanation

In California, the maximum speed limit on most highways is 65 mph unless otherwise posted. Drivers must never exceed the speed limit and should reduce their speed when there is heavy traffic, bad weather, or unsafe road conditions. This follows California’s "Basic Speed Law," which states that drivers must always travel at a safe speed based on current conditions, regardless of the posted limit.
