242. Night blindness

Night blindness, also called nyctalopia, is reduced ability to see in darkness or low-light conditions. It can make it difficult to recognise pedestrians, cyclists, road markings, bends or obstacles at night and during twilight. Night blindness can have different causes, including certain eye conditions, vitamin deficiencies or problems with the retina. Drivers who have difficulty seeing in low light should avoid driving in conditions where their vision is inadequate and seek professional eye care.

Are there minimum vision requirements for driving at night in Belgium?

Yes. Belgian driving-fitness standards consider several aspects of vision, including visual acuity, visual field, twilight vision, sensitivity to light and contrast and other visual functions needed for safe driving.

What should you do if you have difficulty seeing at night in Belgium?

If your vision may no longer meet the driving-fitness standards, you should have it assessed by an ophthalmologist. The ophthalmologist can determine whether you remain medically fit to drive or whether further assessment is needed.

Can night blindness affect your Belgian driving licence?

Yes. If reduced night or twilight vision affects driving fitness, a driver may be declared fit with conditions or restrictions, temporarily unfit or unfit to drive, depending on the medical assessment.

Can a Belgian driving licence restrict you to daytime driving?

Yes. A person who remains fit to drive only under certain conditions can receive an adapted driving licence with restrictions. One possible restriction is driving only during daylight.

Do Belgian licence applicants have to meet visual requirements at night?

Yes. Applicants for group 1 licences must declare that, with or without optical correction, they have sufficient visual acuity, including at night. If they cannot meet the required visual standards, a medical examination is necessary.

Who assesses visual fitness to drive in Belgium?

When vision may be insufficient, an ophthalmologist assesses driving fitness. The driver may also be referred to CARA or another authorised driving-fitness centre for further evaluation when necessary.
