Tennessee Ignition Interlock: No Employer Exemption

Understanding Tennessee's strict no-exemption policy for work vehicles and practical employment alternatives

Tennessee Does NOT Allow Employer Exemptions

Tennessee law is clear: you must install an ignition interlock device on ALL vehicles you operate, including employer-owned vehicles. There are NO exceptions for work vehicles, company cars, or employer-owned fleets. This is one of the strictest interlock policies in the United States.

Tennessee's No-Exemption Policy

Unlike many other states, Tennessee does not recognize any exemptions for employer-owned vehicles. The law requires that every vehicle you operate must have an ignition interlock device installed, regardless of who owns it. This creates significant challenges for employees who need to drive as part of their job.

What Tennessee Law Requires

  • Interlock required on ALL vehicles you drive
  • Applies to personal AND employer vehicles
  • No work-related exemptions exist
  • No commercial vehicle exemptions

Impact on Employment

  • Many employers cannot accommodate interlock devices
  • Some jobs requiring driving may be unavailable
  • Practical alternatives exist (see below)
  • Open communication with employer is crucial

Employer Options When Employee Requires Interlock

When an employee is required to install an ignition interlock device, Tennessee employers have three primary options:

Option 1: Install Interlock Device on Company Vehicle

The employer can choose to install an ignition interlock device on the company vehicle. This allows the employee to continue driving for work.

Pros:

  • • Employee maintains full job duties
  • • Complies with Tennessee law
  • • Retains experienced employee

Cons:

  • • Cost: $70-150/month per vehicle
  • • Installation: $100-200 initially
  • • Other employees must use device too
  • • Maintenance and calibration required

Option 2: Restrict Employee from Driving

The employer can restructure the employee's role to eliminate driving responsibilities. Employee remains employed but cannot operate company vehicles.

Pros:

  • • No installation costs
  • • Retains employee in modified role
  • • Complies with Tennessee law

Cons:

  • • May require role restructuring
  • • Possible reduction in responsibilities
  • • May affect compensation
  • • Not feasible for all positions

Option 3: Terminate Employment

If the position requires driving and the employer cannot or will not install an interlock device, termination may be the only option. Tennessee is an at-will employment state.

Note: Many employers choose this option due to cost concerns or insurance requirements. If your job requires driving, discuss your situation with your employer as soon as possible to explore alternatives before making any decisions.

Practical Employment Alternatives

If your employer cannot or will not install an interlock device, these alternatives may help you maintain employment:

Use Personal Vehicle with Interlock

Install an interlock device on your personal vehicle and use it for work duties. Request mileage reimbursement from your employer. This works well for sales, service, or delivery positions where you don't need a company-branded vehicle.

Arrange Alternative Transportation

For positions requiring occasional travel to work sites, arrange to carpool with coworkers or use rideshare services. Some employers will cover these transportation costs rather than install interlock devices.

Seek Non-Driving Positions

Consider transitioning to a role within your company that doesn't require driving. Many office, technical, customer service, or remote positions may be available that don't involve operating vehicles.

Request Role Modification

Work with your employer to restructure your role. For example, a field technician might become a shop-based technician with coworkers handling the driving portion of service calls.

Employer Pays for Interlock Installation

Propose that you continue in your role with the employer covering the interlock device costs ($70-150/month). This may be more cost-effective than hiring and training a replacement employee. Present it as a business decision.

Tennessee Interlock Requirements and Penalties

Critical Warning: Tennessee takes interlock violations extremely seriously. Law enforcement actively monitors compliance. Driving any vehicle without an interlock device will result in immediate arrest, mandatory jail time, and extended interlock requirements. Do not risk violating these rules.

How to Discuss This with Your Employer

Having this conversation with your employer is difficult but necessary. Here's how to approach it professionally:

1

Be Proactive and Honest

Schedule a private meeting with your supervisor or HR department as soon as you know about the interlock requirement. Being upfront demonstrates responsibility and gives more time to find solutions.

2

Explain Tennessee Law

Clearly explain that Tennessee law requires interlock devices on ALL vehicles you operate, including company vehicles. There are no exemptions. Show them this page or Tennessee DMV resources if needed.

3

Present Solutions

Come prepared with alternatives: offer to use your personal vehicle with interlock, suggest role modifications, or propose that the company install an interlock device (with you possibly contributing to costs).

4

Emphasize Your Value

Remind your employer of your skills, experience, and contributions. Present the interlock as a temporary situation with a specific end date. Hiring and training a replacement employee is often more expensive than accommodating the interlock requirement.

5

Put Agreements in Writing

Once you reach an agreement, get it in writing. Document any changes to your role, compensation, or vehicle usage. This protects both you and your employer.

Important: Under Tennessee law, you cannot be convicted solely because your employer refuses to install an interlock device. However, you cannot drive for work without one. If your employer terminates you, you may be eligible for unemployment benefits - consult with an employment attorney if this occurs.
