185. Health

Health can affect a person’s ability to drive safely. Illness, injury, poor vision, reduced mobility, fatigue, certain medical conditions and some medicines can interfere with concentration, reaction time, judgement or vehicle control. Drivers should recognise when their physical or mental condition may make driving unsafe and should seek medical advice when necessary. In some countries, specific health conditions must be reported and may require a medical examination or restrictions on the driving licence.

How can health affect driving?

Health problems can affect vision, concentration, reaction time, judgement, coordination and vehicle control, making safe driving more difficult.

Should you drive when you are ill?

Not if the illness makes it difficult to concentrate, react quickly or control the vehicle safely. Drivers should delay the journey or seek medical advice when necessary.

Can medication affect driving?

Yes. Some medicines can cause drowsiness, dizziness, blurred vision or slower reactions. Always follow the instructions provided with the medicine and advice from a healthcare professional.

Can poor eyesight affect driving?

Yes. Good vision is essential for recognising traffic signs, road users, hazards and changes in traffic conditions. Many countries set minimum eyesight requirements for drivers.

Can a medical condition affect a driving licence?

Yes. Depending on the country and condition, a driver may need a medical assessment, licence restriction or adapted vehicle before being permitted to drive.

Who is responsible for deciding whether someone is fit to drive?

This depends on local law. The driver usually has a responsibility to ensure they are fit to drive, while doctors or specialised assessment centres may evaluate driving fitness when required.
