Notes for supervisors of HGV/PSV drivers, i.e. lorry or bus drivers

Using the HGV/PSV option SeeDrivePro tests at standards equivalent to Snellen 6/7.5 and 6/60 visual acuity. It is a more advanced test than the car and van drivers’ number plate test described below.

Each eye has to be tested separately using smaller letters which must be read correctly by at least one eye. The other eye must at least read the larger letters correctly.

The above visual acuity test complies with the FORS recommendations for vision tests every 6 months.

If a driver fails SeeDrivePro they should be advised to visit an optometrist or ophthalmologist for further investigation and advice.

Additionally, the DVLA also requires that drivers should have full and normal side vision when looking straight ahead. If in doubt a driver’s visual field test called an Esterman test, can be carried out by an optometrist or ophthalmologist.

Notes for supervisors of car and van drivers

If the driver makes a simple mistake, confusing O for Q for example, repeat the test once more. He/she must then pass on the second attempt to continue driving. There is a REPEAT button.

Click on “PASS” or “FAIL” buttons, (next page), depending on the outcome.

In the case of an objection being raised, the driver must then be tested in the street with a genuine number plate

  • The law states that drivers must be able to read a clean number plate in good daylight.
  • Drivers must be able to read a car number plate made after 1 September 2001 from 20 metres.
  • Before 1st September 2001 number plates were a little larger and should be read from a distance of 20.5 metres.
  • SeeDrivePro equates to a clean number plate in good daylight.
