Should I display DOT or USDOT before my regulation numbers? Which one is correct?  

A lot of our customers believe that displaying DOT ###### is sufficient; when really US before DOT is REQUIRED.

You should always display USDOT or US DOT before your regulation numbers. The Department of Transportation (DOT) will give you a warning or could even give you a fine if you’re displaying your regulation number incorrectly.

At US Decals, we make sure you order the correct regulation decal to meet vehicle code. If you have any questions or concerns please don’t hesitate to contact us with your USDOT Decal needs.
