Frequently asked questions
How do I check if a charter bus company is FMCSA-compliant?
Look up the carrier's USDOT number on safer.fmcsa.dot.gov. The public SAFER System shows current operating authority status (active, revoked, suspended), safety fitness rating (Satisfactory, None, Conditional, Unsatisfactory), insurance on file, and recent inspection history. Every BusBrother carrier has a public USDOT record with Satisfactory or None rating.
What is the difference between USDOT and MC number?
USDOT number is a unique carrier ID assigned to every commercial vehicle operator. MC (Motor Carrier) number is the operating authority granted by FMCSA for interstate for-hire transportation of passengers. All BusBrother interstate carriers have both; some intrastate-only carriers have only a USDOT number.
What are CSA safety scores?
CSA (Compliance, Safety, Accountability) scores measure a carrier's safety performance across 7 categories called BASICs (Unsafe Driving, Hours of Service, Driver Fitness, Controlled Substances, Vehicle Maintenance, Hazardous Materials, Crash Indicator). Scores range 0 to 100. Above the intervention threshold triggers FMCSA action. BusBrother carriers stay well below intervention thresholds.
How often are charter buses inspected?
Federal FMCSA rule 49 CFR 396.17 requires annual DOT vehicle inspections for every commercial motor vehicle. Inspection records are kept on file and available on request. Roadside inspections happen throughout the year at random checkpoints - vehicles with defects are placed out of service until repaired.
What happens if a driver violates hours-of-service?
Hours-of-service violations trigger CSA points against the driver and carrier. Accumulating violations lead to driver disqualification and carrier intervention. Electronic logging devices (ELDs) required since 2019 automatically record driving hours so cheating is detectable at any roadside inspection.
