California Vehicle Code 21703 prohibits drivers, including commercial truck drivers, from following another vehicle more closely than is reasonable and prudent given speed and traffic conditions. Multi-vehicle pileups on freeways like Highway 99 often involve a following-too-closely violation, particularly when a heavy truck cannot stop in time for slowed or stopped traffic ahead. A violation of this statute can support a finding of negligence in a civil injury or wrongful death claim.
Vehicle Code 22350, the basic speed law, requires drivers to travel at a speed that is reasonable and prudent for existing conditions, regardless of the posted limit. Investigators examining chain-reaction crashes involving big rigs frequently look at whether speed was appropriate for traffic congestion, visibility or roadway hazards. If a truck or passenger vehicle was traveling too fast for conditions, that finding can be central to establishing fault.
