How to Obtain Your USDOT Number for a New Bus in 2025
If you plan to operate a commercial bus—whether a charter service, shuttle fleet, or interstate tour—in 2025, securing a USDOT number is your first legal requirement. The Federal Motor Carrier Safety Administration (FMCSA) uses this unique identifier to track safety records, inspections, and compliance.
This guide explains who needs a USDOT number, how to apply, display requirements, and best practices to keep your operation running smoothly.
Why a USDOT Number Matters
- Legal Compliance: Required for any interstate passenger transport, vehicles over 10,000 lbs GVW, or those carrying 9+ passengers for compensation.
- Safety Tracking: Links your business to FMCSA inspection and crash data.
- Regulatory Transparency: Law enforcement and state agencies use it to verify authority and safety status.
- Operational Legitimacy: Operating without one risks fines, shutdowns, and revoked licenses.
