Pa. carriers must display DOT number

Jill Dunn | November 04, 2010

Pennsylvania carriers in intrastate commerce now must have a U.S. Department of Transportation number, joining 30 other states with this requirement. 

Even if operating in state, Pennsylvania carriers must display the DOT number and the business name on both sides of commercial vehicles.

A new rule enacted earlier this year requires the number to help identify carriers with serious safety violations discovered during roadside inspections or following truck crashes. Unsafe carriers will be notified of deficiencies and may undergo an operational review to bring them into compliance.

Other states with the mandate are Alabama, Alaska, Arizona, Colorado, Connecticut, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, New York, Nebraska, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Washington, West Virginia, Wisconsin, and Wyoming.

More information is available at or (717) 783-5556.
Carriers can obtain a USDOT number free by visiting and registering under the heading “Registration and Licensing.”
