Most FasTrak toll lanes on bridges have a speed limit of 25 miles per hour (mph). This limit is enforced by the California Highway Patrol.
For toll lanes that are shared between FasTrak and cash paying motorists, FasTrak users should proceed with extreme caution, being alert for stopped vehicles and toll collectors.
For Bay Area toll bridges with open road tolling lanes (e.g., Benicia-Martinez Bridge), the posted speed limit is 55 mph.
