Vision and Visability

Vision and visibility refer to the ability to see and to be seen in all conditions and is fundamental to road safety. Good visibility is dependent on several components in a vehicle that are all checked during the vehicle inspection: the windshield, the condition of the windows, mirrors, windshield wipers, windshield washer and the demisting system.

Windshield and other Glazing

ROLE: it protects the driver and the passengers from bad weather conditions, dirt and debris and it ensures vision on the road remains as clear as possible.
It also contributes to the rigidity of the vehicle structure and protects drivers and passengers from impact and injury.
Risks if non-compliant:
  • The windshield can be weakened and damaged if it has suffered an impact causing chips or cracks. This damage can impair the driver’s vision, leading to eyestrain and tiredness and increase the risk of accidents.
  • Stickers or labels can obstruct vision and increase the risk of accidents.
  • If the windshield is not securely and correctly fitted it may lower the rigidity and stability of the vehicle. It may lead to windshield leaks causing damage to the dashboard and even electrical breakdowns.


ROLE: to allow drivers to see to the side and rear of the vehicle. The number and location of mirrors depend on the vehicle type and age.
Risks if non-compliant:
  • If mirrors are damaged or incorrectly positioned, the ability to see and observe will be greatly reduced, therefore increasing the risk of accidents.
  • Protruding parts might cause additional harm in the event of a collision with a pedestrian (for instance mirrors may be at the same height as a child's head).

Windshield Washer

ROLE: to spray fluid onto the windshield in order to facilitate the cleaning of a dirty windshield.
Risks if non-compliant:
  • It may be impossible to clean the windshield with the wipers alone and doing so may reduce visibility by "spreading" the dirt, this will lead to an increased risk of an accident.

Windshield Wiper

ROLE: to remove rain, snow, dirt, pollen, frost and other debris quickly and smoothly at the push of a button.
Risks if non-compliant:
  • Visibility will be reduced if the wipers are damaged or worn, this will increase the risk of accidents especially if it is raining or snowing.

Windshield Defrosting and Demisting System

ROLE: to eliminate fog and mist on the inside surface of the windshield.
Risks if non-compliant:
  • The driver’s ability to see the road will be impeded, leading to eyestrain, fatigue and increased risk of an accident.
