A new study by an insurance trade group says the new hours-of-service rule has resulted in truckers driving more and being slightly more fatigued than under the old rule.
However, a report from the American Trucking Associations shows that the Insurance Institute for Highway Safety study is “bogus, as usual,” said ATA spokesman Mike Russell.
While the drivers responding to the IIHS study said their sleep time had increased under the new rule, they reported slightly more instances than when the old rule was in effect of driving drowsy or falling asleep at the wheel. When drivers were asked about dozing at the wheel at least once in the past month, the reported percentage increased from 13 percent in 2003 to 15 percent in 2004.
“The new rule was supposed to improve safety, but our survey shows the opposite,” says Anne McCartt, IIHS vice president for research. “Truckers are using the restart provision to squeeze even more driving hours into the week.”
A work week restart provision of the current rule, requiring 34 hours off, increases allowable driving hours in a seven-day period from 60 to 77. The rule lengthens the mandatory rest period by two hours but lets drivers stay on the road an extra hour every day.
A quarter of drivers who were surveyed by IIHS said they drive more than the new daily limit of 11 hours. Eight of 10 drivers said they’re taking advantage of the restart provision that allows them to drive 25 percent more in a week.
The ATA study, based on government accident records and data from 70 carriers operating under the new rule, was presented March 10 to the Federal Motor Carrier Safety Administration as comment on the possible revision of the hours rule. ATA asks that the rule receive no major changes.
