A new government rule is changing the way truckers do business.

FOX News' Jeff Monosso has more:

Commercial truck and bus drivers have been required for years to keep logs of their driving hours on paper, but a new rule by the Federal Motor Carrier Safety Administration will require an estimated 3-million truck and bus drivers to record their hours behind the wheel electronically.

Which officials say would make it harder to evade restrictions on hours and to prevent fatigue. Though the Owner-Operator Independent Drivers Association, which sued to block the rule, calls it unproven technology.

Safety officials also say it'll save billions in paperwork costs, prevent injuries, and save lives.
