The Driver and Vehicle Licensing Agency has urged drivers to check their eyesight ahead of the winter months.
As the dark nights set in, it is increasingly important motorists check their vision meets the required standard - as The Daily Record reports.
Reduced daylight hours and poor weather conditions can lead to reduced visibility on the roads.

The DVLA require drivers across the UK to read a car number plate from 20 metres away.
The number plate must be made after September 1 2001 - and motorists who require contact lenses or glasses will be able to wear them during the test.
Drivers must also have an adequate field of vision - and can consult their optician for further information on this.
How do you perform the test?
Anyone can do the test at any time - and the number plate test is a simple and effective way to check if your eyesight meets the required standard for driving.
To conduct the test, 20 metres is roughly the length of five parked cars or two double decked buses.
When should I tell the DVLA about a change in eyesight?
You must inform the DVLA if you have any problems with your eyesight that impacts both your eyes, or the remaining eye you have if you only have one eye.
This does not include being long sighted, short sighted or colour blind.
You also do not need to say if you’ve had surgery to correct short-sightedness and can meet the eyesight standards.
