DOT Violations and Drivers with Multiple Employers: Understanding the Rules

For drivers under Federal Motor Carrier Safety Administration (FMCSA) regulations, managing compliance when working for multiple employers can get complex—especially when a violation occurs. Both drivers and employers have defined responsibilities, and understanding these rules is essential for staying compliant.

1. Drivers Must Notify All Employers of a Violation

If a driver working for multiple employers receives a DOT drug or alcohol violation, they must inform all their other employers in writing. This includes side jobs or any additional safety-sensitive roles.

Challenges in Practice:

1. This requirement is often overlooked.
2. Many employers only find out about a violation during the annual limited Clearinghouse query, which creates compliance risks if the driver is still operating in a safety-sensitive capacity.

Employers should make this rule clear during onboarding and training to reduce the risk of noncompliance.

2. Handling SAP Reports and Follow-Up Plans for Multiple Employers

When a driver with multiple employers has a violation, the SAP report and follow-up testing plan must be sent to each employer. Every employer is independently responsible for implementing and completing the full plan.

Important Notes:

1. Employers cannot split or share responsibility.
2. Each employer must follow through with the complete plan, regardless of the driver’s other employment.

This ensures consistency and compliance across all workplaces where the driver operates.

3. FMCSA Vehicle Criteria and Additional Insights

Drivers fall under FMCSA rules if they:

1. Operate a vehicle with a gross vehicle weight rating of 26,000+ pounds
2. Drive a vehicle designed to transport 16+ passengers (including the driver)
3. Operate any vehicle requiring hazardous materials (hazmat) placards

Examples:

1. A smaller delivery van carrying hazmat (like oxygen tanks) must follow FMCSA rules
2. A 16+ passenger rental van used as an airport shuttle also qualifies

Employers should verify that all qualifying vehicles are correctly classified and that drivers comply with FMCSA drug and alcohol testing requirements.

Key Takeaways for Employers and Drivers

1. Drivers must notify all employers in writing if they have a violation.
2. Each employer is solely responsible for completing the SAP’s follow-up testing plan—no splitting duties.
3. Vehicles that meet FMCSA criteria, even if small or rented, must be covered under proper DOT regulations.
   
   

Final Thoughts

For drivers juggling multiple employers, DOT compliance depends on transparency and strong coordination. Employers should train their teams, reinforce notification rules, and stay consistent with Clearinghouse queries to minimize risk and maintain workplace safety. Clear processes and ongoing education create a stronger, more accountable safety culture.
