ATTENTION:

Diesel Fuel Users: Please be advised that the National and State Covid-19 Emergency Declaration does not include the ability to use non-taxed diesel fuel (dyed diesel) in motor vehicles traveling on public roads and highways. Using dyed diesel on Montana roadways could be result in a penalty not to exceed $1,000.00 for a first offense and $5,000.00 for a second offense.

USDOT Number updates: needed for Intrastate and Interstate carriers, this is a free service that is done by FMCSA and MCS/MDT. You will not receive calls from either entity requesting money to update this for you. If you receive a call from someone offering to do this for you for compensation, this is a scammer. To update your information, please see our FMCSA Page
