Frequently Asked Questions

Why is the Federal Motor Carrier Safety Administration requiring these devices?

The U.S. Congress required the Federal Motor Carrier Safety Administration, or FMCSA, to publish a rule (mandate) requiring these devices in commercial motor vehicles. Additionally, Congress required the agency to make this rule apply to motor carriers and their drivers within two years of publishing the rule.

The FMCSA estimates the rule will help avoid 1,844 crashes, 562 injuries and save 26 lives annually. This data is based on improved compliance with Hours of Service (HOS) regulations.
