The National Transportation Safety Board (NTSB) has reiterated previous recommendations issued in 2001 calling for the National Highway Traffic Safety Administration to create standards for collision warning systems and require their installation on all newly manufactured commercial vehicles, according to NTSB information.
This action follows the board's investigation of an Oct 1, 2003, tractor-trailer fatal accident at an Illinois toll booth. NTSB determined that if the truck had been equipped with a collision warning system, the crash might have been avoided.
The tractor-trailer involved in the accident, moving at about 50 miles per hour, hit the rear of a 25-passenger specialty bus, which traveled forward striking a pickup truck and pushing it into the rear of another tractor-trailer. Eight passengers on the specialty bus were killed in the accident.
