What are the pathologies incompatible with driving?

Diabetes, Alzheimer’s, heavy motor and hearing disabilities: the list of pathologies incompatible or compatible under certain conditions with driving has been updated since Monday, the day after the publication of a decree in the official journal.

This decree of March 28 from the Ministries of the Interior and Health repeals the old one of December 21, 2005 in order mainly to take into account “scientific and technological innovations”, in terms of fitting out the passenger compartment and driving assistance in particular.


Drivers with uncomplicated diabetes whose treatment does not generate a risk of hypoglycaemia will no longer be required to pass a medical check beforehand to drive light vehicles (cars and two-wheelers).

Locomotor disabilities and hearing loss

People with very severe locomotor disabilities and profound hearing loss will now be able to drive heavy goods vehicles and public transport vehicles, after an examination validated by an approved doctor and a driving license inspector.

The decree also lifts bans on the driving of light vehicles for people with certain very severe locomotor disabilities.

Alzheimer’s and neuroevolutionary diseases

It also clarifies the moment from which a person suffering from Alzheimer’s disease and related neuroevolutionary diseases can no longer drive. While the previous decree set the limit from the moment the person is suffering from “documented dementia”, that of March 28 specifies that there is definitive incompatibility with driving “from the start of stage 3 of the scale of Reisberg”, which measures the progression of the disease.

“This is when friends, family and colleagues start noticing certain memory or concentration problems. In practice, for driving, the person no longer pays attention to certain red lights, for example, ”explains Road Safety. “For the person to stop driving at the right moment, the people around must be able to “organize things”. The decree clarifies this point, the dementia mentioned in the previous text being a vague notion, ”adds Road Safety.

Benoît Durand, director general of France Alzheimer, points to “a radical cleaver”. “The text says that from the onset of cognitive decline and in particular pathological decline of the Alzheimer’s type, there is a total ban on driving, but who is going to decide? Often for a diagnosis, it takes an appointment with the neurologist, which in some regions, is not obtained before delays of 12 to 18 months. What happens in the meantime? he wonders.

According to Road Safety, the decision will be taken by doctors approved by the Federation of Memory Centers, with whom it has signed an agreement, and hopes for the most reasonable delays possible.
