What the Law Says

California Vehicle Code 21703 requires all drivers, including commercial truck operators, to maintain a safe distance behind the vehicle ahead so they can stop in time if traffic slows or stops suddenly. Investigators examining this four-vehicle crash will likely consider whether the dump truck or another driver allegedly failed to leave adequate following distance before impact. Inadequate spacing is a common contributing factor in chain-reaction crashes involving heavy trucks.

California Vehicle Code 22406 limits trucks with three or more axles, including dump trucks, to a maximum speed of 55 mph on highways, reflecting the longer stopping distances and rollover risks heavier vehicles present. If the dump truck involved in this crash was allegedly traveling too fast for conditions at the busy Arrow Highway and Avenida Barbosa intersection, that could be a significant factor in how the collision unfolded and in any liability determination.
