What does 49 CFR 392.6 (Schedules to conform with speed limits) require?

Short answer

No motor carrier shall schedule a run that would require a commercial motor vehicle to be operated at speeds greater than those prescribed by the jurisdictions in or through which the vehicle is being operated. This means that motor carriers must plan routes and schedules that allow drivers to comply with all applicable speed limits.

The rule says

"No motor carrier shall schedule a run nor permit nor require the operation of any commercial motor vehicle between points in such period of time as would necessitate the commercial motor vehicle being operated at speeds greater than those prescribed by the jurisdictions in or through which the commercial motor vehicle is being operated." (49 CFR 392.6)

In plain English

In practice, this means that motor carriers must take into account the speed limits on the routes their drivers will be taking, as well as any potential traffic or road conditions that could slow them down. If a driver is unable to complete a route without speeding, the motor carrier may be in violation of this rule. Inspectors may review a motor carrier's schedules and routes to ensure compliance with this regulation.

What to do

• Review your company's scheduling practices to ensure they allow drivers to comply with speed limits.
• Take into account potential traffic and road conditions when planning routes and schedules.
• Train drivers on the importance of complying with speed limits and the company's scheduling policies.
• Regularly review driver logs and other records to ensure compliance with this regulation.
