Ensuring the safety of America’s roads, skies, rails, and pipelines requires more than just technical skill—it requires trust. The U.S. Department of Transportation (DOT) mandates background checks for employees in safety-sensitive positions across multiple agencies. These checks confirm that workers are qualified, compliant, and safe to perform critical duties.
While each modal agency has specific requirements, the best practice for employers is to go beyond the minimum. Enhanced background screening reduces liability, strengthens compliance, and improves retention by ensuring the right employees are hired from the start.
DOT Modal Agencies Covered by Background Screening
DOT background checks apply to employees regulated under:
- FMCSA (Federal Motor Carrier Safety Administration) – Commercial drivers of trucks and buses.
- FAA (Federal Aviation Administration) – Pilots, mechanics, and aviation safety-sensitive personnel.
- FTA (Federal Transit Administration) – Public transit system operators and staff.
- FRA (Federal Railroad Administration) – Railroad operators and safety-sensitive staff.
- PHMSA (Pipeline and Hazardous Materials Safety Administration) – Workers transporting or handling hazardous materials.
- USCG (U.S. Coast Guard) – Maritime safety-sensitive employees.
Each agency’s requirements vary, but all share the same goal: ensuring safety and compliance in highly regulated industries.
FMCSA Background Checks (Commercial Motor Vehicle Drivers)
FMCSA Background Checks (Commercial Motor Vehicle Drivers)
For trucking and bus operators, DOT requires the following under FMCSA:
- Motor Vehicle Record (MVR) – At least 3 years of driving history, including violations, suspensions, and accidents.
- DOT Employment Verification – Three years of safety-sensitive employment history, including drug/alcohol testing records.
- FMCSA Drug & Alcohol Clearinghouse Query – Required before hire and annually thereafter to identify unresolved violations.
- DOT Physical Exam – Medical certification of fitness to drive.
- Pre-Employment Drug Test – A negative result required before operating a CMV.
FMCSA Best Practices
Forward-thinking employers add:
- PSP (Pre-Employment Screening Program) – FMCSA inspection and crash history.
- CDLIS (Commercial Driver’s License Information System) – Identifies multiple licenses in different states.
- County and State Criminal Searches – Uncover local convictions not captured in national databases.
- SSN Trace & Address History – Verifies identity and directs jurisdictional searches.
- NatCrim (National Criminal Database) – Fills gaps but must be verified at the source.
These checks help employers avoid costly turnover and ensure only qualified drivers are behind the wheel.
FAA Background Checks (Pilots, Mechanics, Aviation Staff)
For aviation employers, the FAA requires deeper and more specialized background checks:
- FBI/TSA Fingerprinting – Mandatory for pilots, mechanics, and many aviation roles.
- Pilot Records Database (PRD) Query – Required under 14 CFR Part 111. Provides pilot training, certification, and safety history.
- Drug & Alcohol Records (49 CFR §40.25) – Employers must obtain prior DOT-regulated drug/alcohol testing records.
- DOT Physical Certification – Verification of medical fitness for flight crew.
- Pre-Employment Drug Test – Required for safety-sensitive positions.
FAA Best Practices
To strengthen compliance and mitigate risk, employers also use:
- Rap Back Program (FBI Fingerprint Monitoring) – Provides ongoing alerts if an employee is arrested after hire.
- Annual or Time-Specific Re-Screens – Keeps background records current.
- County, State, and Federal Criminal Searches – Identifies felonies and misdemeanors, including fraud, trafficking, and theft.
- Sex Offender Registry Checks – Particularly important for passenger-facing roles.
- Patriot Act / OFAC / Sanctions Lists – Screens against terrorism, sanctions, and Most Wanted lists.
FAA employers are also encouraged to develop role-based packages—for example, more intensive checks for pilots and mechanics versus tailored packages for administrative staff.
Other DOT Modal Requirements
- FTA (Transit) – Employment verification, criminal history, and drug/alcohol testing.
- FRA (Railroad) – Safety-sensitive background checks, employment verification, and drug/alcohol testing.
- PHMSA (Hazmat) – Criminal checks and security threat assessments, especially for drivers handling hazardous materials.
- USCG (Maritime) – Screening for credentials, prior employment, and drug/alcohol compliance.
Why Best Practices Matter
Employers that go beyond the minimum background checks benefit from:
- Stronger Compliance – Reduces audit risk and penalties.
- Improved Safety – Identifies high-risk hires before they cause accidents.
- Reduced Turnover – Proper vetting leads to better hiring decisions and higher retention.
- Public Trust – Safer operators mean safer roads, skies, rails, and pipelines.
