NTSB: Single-unit trucks should fall under other large truck safety rules
Single-unit trucks – large trucks with a gross vehicle weight rating of more than 10,000 pounds and all axles attached to a single frame – comprise 3 percent of all registered motor vehicles and 4 percent of motor vehicle miles traveled. However, they cause 9 percent of fatalities among passenger vehicle occupants in multi-vehicle crashes because of differences in structure and bumper height, according to NTSB.
NTSB recommended the following large truck safety rules apply to single-unit trucks:
- Improved rear and side under-ride protection systems
- Enhanced visibility of the truck for other roadway users
- Technologies to compensate for large truck blind spots
- Proposed mandatory electronic stability control installation
NTSB also recommended the Federal Motor Carrier Safety Administration conduct a study on the benefits of extending stricter licensing requirements to drivers of single-unit trucks.
