Grey fleet drivers are the staff whose licences employers most often fail to check. They drive their own cars, so they never appear on a vehicle list, a fuel card or a telematics account. In a July 2025 survey by TTC Group, 49% of employees who drive their own car for work could not recall their employer ever checking their licence. TTC also said that a fifth of the 70,000 driver validation checks it ran for clients failed.
The duty of care is the same as for a company car. This guide covers how to find your grey fleet drivers, how to check their licences, how often, and what to do when a check fails. For how DVLA checks work in detail, see our driver licence checks guide.
Why grey fleet licences get missed
- No vehicle record. Licence checks are often triggered when a driver is given a company vehicle. Grey fleet drivers never are.
- Occasional drivers. Someone who drives to a client twice a year does not think of themselves as a driver, and nor does their manager.
- Ownership sits nowhere. HR holds the employee, finance pays the mileage, and the fleet manager looks after company vehicles. Nobody owns the grey fleet.
- Drivers do not report points. A driver who picks up points or a ban in their own car rarely tells their employer. Without a recheck, you find out after a crash.
Step 1: find every grey fleet driver
Your mileage claims are the most complete list you have. Anyone who claimed business mileage in the last 12 months drove their own vehicle for work.
| Source | Who it finds |
|---|---|
| Expenses and mileage claims | Anyone who claimed business mileage |
| Payroll | Staff on a cash car allowance |
| Job descriptions and adverts | Roles that need a licence or travel between sites |
| Line managers | Occasional drivers who never claim |
Match the list against the drivers you already check. Everyone left over is unchecked.
Step 2: get consent and run the first check
Every DVLA check needs the driver's consent. For grey fleet, the practical route is a licence checking provider connected to the DVLA: the driver signs an electronic declaration once, and you can then check on a schedule for up to 3 years without asking again. The alternative is a check code the driver creates on GOV.UK, which lasts 21 days and works once. That suits a one-off check, not a schedule.
Check before the first work journey, not after. Put it in your grey fleet policy: no licence check, no business mileage paid. Tying the check to mileage payments is the simplest way to make it stick.
Step 3: recheck on a schedule
A licence that was valid in January can carry a ban by June. Set the recheck interval by penalty points, the same way you would for company drivers.
| Points on licence | Suggested check frequency |
|---|---|
| 0–5 | Every 6 months |
| 6–8 | Every 3 months |
| 9 or more | Monthly |
| Not allowed to drive | Monthly, until resolved |
There is no legal frequency. Whatever you choose, write it in your policy and apply it to grey fleet and company drivers alike.
Step 4: act when a check fails
- Stop work driving if the licence is invalid, expired, revoked or disqualified. Tell the driver and their manager, and record that you did.
- Stop the mileage. No business mileage claims until a new check passes.
- Check for a data issue. Some fails are a name or address mismatch the driver can fix with the DVLA.
- Recheck and record. Clear the driver only when a new check passes, and keep the check, the decision, who made it and when.
Licence, insurance and MOT go together
A valid licence is one of three checks for grey fleet. The other two are business-use insurance and a current MOT. In the same TTC survey, only 35% of grey fleet drivers had been asked for evidence of insurance. Run all three together, and recheck insurance and MOT at each expiry date. Our grey fleet audit checklist covers the full set.
US fleets: MVR checks for personal vehicles
In the US, the equivalent of a licence check is a motor vehicle record (MVR) check, pulled from the state that issued the driver's licence. If an employee crashes their own car on company business, the employer can be sued as well as the driver, and a claim of negligent entrustment asks whether the employer knew, or should have known, the driver was unsafe. An MVR on file is how you show you checked.
- Check at hire and at least once a year. That is the common recommendation from fleet insurers.
- Get written consent. If you order MVRs through a background check company, the Fair Credit Reporting Act requires a standalone written disclosure and the employee's written authorisation first, and notice before you act on a bad result. State rules can add more.
- Check insurance limits. Set minimum liability limits on the employee's personal auto policy, and ask for proof at each renewal.

How Fleevo runs grey fleet licence checks
Fleevo checks driving licences against DVLA records for every driver, including grey fleet drivers who never touch a company vehicle. Each driver gets a link by text, WhatsApp or email to sign the DVLA declaration on their phone, and reminders go out automatically until they do. Checks then repeat on a schedule set by penalty points: by default every 6 months at 0 points, every 3 months at 6 points and monthly at 9 points. You can change every band.
A driver who is not allowed to drive goes on a to-do list until someone confirms they are off the road, and a daily email lists anything that needs attention. Drivers with non-GB licences upload photos for approval, and a CSV export gives auditors the full record. Explore Fleevo driver licence checks, or talk to us about licence checks.
Grey fleet licence check FAQs
Do employers have to check grey fleet drivers' licences?
The law does not name a check, but the Health and Safety at Work etc. Act 1974 requires employers to manage the risks of work driving, and HSE's guidance applies it to employees' own vehicles. A licence check is the basic step to show the driver can legally drive.
How often should you check a grey fleet driver's licence?
At least every 6 months for drivers with few or no points, every 3 months at 6 points or more, and monthly at 9 points or more. Check before the first work journey.
Can I check an employee's licence without their consent?
No. A DVLA check needs either a check code the driver creates or a declaration they sign.
What if a grey fleet driver refuses a licence check?
Treat it as not allowed to drive for work. Make the check a condition of business mileage in your grey fleet policy, so the rule is clear before it comes up.
Does an occasional driver need a licence check?
Yes. One work journey in their own car brings the driver into your duty of care for that journey.
What is the US equivalent of a grey fleet licence check?
A motor vehicle record (MVR) check, usually at hire and once a year, with the employee's written consent.
