There are 2 versions of the commercial drivers test designed for either drivers of cars and vans, or drivers of buses and lorries.
Please note that ALL tests should be done wearing spectacles or contact lenses if they have been prescribed for driving.
Instructions for HGV/PSV, generally bus or lorry 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 Estermann test, can be carried
out by an optometrist or ophthalmologist.
Instructions for 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.
