The Federal Motor Carrier Safety Administration on May 2 announced that newly released data show 78 percent of commercial truck and bus drivers wore safety belts while operating behind the wheel in 2010, compared to 74 percent in 2009.
According to FMCSA’s Safety Belt Usage by Commercial Motor Vehicle Drivers Survey, the number of commercial drivers who are wearing safety belts has increased by 14 percent since 2007. The 2010 survey observed 26,830 commercial drivers operating medium- to heavy-duty trucks and buses at 998 roadside sites nationwide.
The survey found that safety belt use for commercial drivers and their occupants was higher, 80 percent, in states where law enforcement may stop drivers for not wearing a safety belt, versus 72 percent in states with weaker secondary enforcement belt use laws.
