The Canadian truck group reminded FMCSA that Canada has had a 13-hour driving limit in place for many decades, and there is no evidence to suggest that this has posed a safety concern. In addition, the new HOS regulations in both Canada (2007) and the U.S. (2004) increased the minimum daily off-duty time by 25 per cent to 10 hours, allowing drivers the opportunity to obtain the amount of sleep acknowledged by scientific experts to be necessary for recovery from fatigue.
The concept of a restart provision was initially proposed in Canada, by CTA. In its petition, CTA argues that Canadian drivers operating on either side of the border are now accustomed to a restart (or reset) period of 36 hours in Canada and 34 hours in the U.S.
The ability to reset the driver’s duty cycle reduces the need to spend an undue amount of off-duty time at the end of a cycle away from home, and most importantly, allows sufficient time for the driver to obtain two principal sleep periods of at least eight hours -- generally considered by scientific experts to be the amount needed to recover from cumulative fatigue, notes CTA.
For now, the Canadian and US trucking industries await FMCSA’s decision, which Transport Topics magazine reported could come by the end of this month.
"It’s a legal and operational twilight zone," says CTA CEO David Bradley. "While FMCSA ponders its next move, carriers and drivers will carry on as if the U.S. hours of service rules have not changed and hope things stay that way; however carriers should be warning their customers of the potential loss of productivity and increased costs that would occur if these two key provisions of the rules are not retained."
