Frequently Asked Questions
How do I check if a carrier MC is active?
Search FMCSA SAFER/Company Snapshot by MC or USDOT and review licensing and insurance. Active without proper insurance filings is not workable.
What is the difference between DOT and MC?
USDOT identifies the carrier in safety systems; MC (operating authority) is required for many interstate for-hire operations. See our MC vs DOT guide.
Can I check authority for free?
Yes via FMCSA public tools. Commercial tools add monitoring and credit layers.
What red flags matter most?
Inactive authority, no/lapsed insurance, high OOS, identity confusion, and refusal to share USDOT.
Should shippers check carriers too?
Absolutely — authority and insurance are baseline vetting before tender.
