Transport hazardous materials.
Carry more than 8 passengers (for hire) or 15 passengers (not for hire).

Most applications are processed immediately when submitted online. With professional filing, you can often receive your DOT Number the same day.
Q2. Do I need a DOT Number for intrastate trucking?
Some states require a DOT Number for intrastate carriers. Always check your state DOT rules, but many small trucking companies still need one even if they don’t cross state lines.

A DOT Number identifies your company for safety and compliance monitoring. An MC Number grants operating authority to carry regulated commodities in interstate commerce. Many carriers need both.

Operating without a DOT Number can result in penalties, vehicle shutdowns, and denied insurance coverage.
