Grandfather Rights on a UK Driving Licence (DVLA)

Posted

In DVLA terms, “grandfather rights” are additional driving entitlements that a driver retains because they held them before licensing rules changed. These rights usually relate to medium-sized lorries (C1) and minibuses (D1) and commonly appear on older car licences.

If you passed your car driving test (Category B) before 1 January 1997, DVLA guidance states that your licence will usually include additional entitlements such as:

  • C1 — medium-sized vehicles
  • C1E (code 107) — C1 with a trailer
  • D1 (code 101) — minibuses with up to 16 passenger seats
  • D1E (code 101) — D1 with a trailer

What can I drive with these rights?

If these categories are shown on your licence, DVLA describes them as follows:

  • C1: vehicles weighing between 3.5 and 7.5 tonnes
  • C1E: a C1 vehicle with a trailer, with a combined maximum weight of 8.25 tonnes only
  • D1: minibuses with 9–16 passenger seats, plus the driver
  • D1E: a D1 minibus with a trailer

Note: DVLA highlights that pre-1997 acquired rights for minibuses are “not for hire or reward.”

What does “not for hire or reward” mean for minibuses?


DVLA explains that you may only drive a minibus on a car licence if it is not used for hire or reward. This means that passengers, or someone acting on their behalf, must not pay for the journey, either directly or indirectly.

Do medical rules apply even if I have grandfather rights?

Yes. Grandfather C1 and D1 entitlements are normally retained only until the licence expires or unless it is revoked for medical reasons. When renewing or reapplying, the higher medical standards for these categories may apply.

Why is age 70 important for drivers with grandfather rights?

For drivers who passed their car test before 1 January 1997, DVLA historically issued licences so that the first formal renewal point was the driver’s 70th birthday.

In practical terms, this meant:

  • The licence remained valid until age 70, unless DVLA was informed of a medical condition earlier
  • Grandfather entitlements (such as C1 and D1) were carried forward automatically
  • There was no routine requirement to reapply or submit medical evidence

What happens at age 70?

DVLA guidance confirms that if you are aged 70 or over and wish to keep your C1 or D1 entitlement, you must submit a D4 medical form, and this is then typically required every three years to retain those categories.
