Should there be a minimum IQ to get a driver's license?

Contact the DMV and report the situation.

If they were not made aware of her injuries and now deficits, there would be no trigger for her to have her driving privileges pulled. A report could do that.

Just a warning though- as it is now, she is likely insured. I have known a person with a TBI who should not have been driving, but along with the impaired judgement comes bad decisions like driving without a license. if her license is pulled, no insurance would cover her victims. if she still had it, there would be a chance they would be covered.

Pulling a license does not, sadly, mean someone won't drive.

But you are correct- if she has mental deficits, her license would likely be pullled.

There should be a minimum IQ to be able to vote

Report your concerns to the DMV.

Report them to the police or the motor vehicle department.

ability not appearances

I have known many people over the years with noticeable brain damage who are excellent drivers. I have multiple sclerosis which is brain damage and it affects the way I walk, yet I ride a motorized trike through the city and drive large trucks when I rent them to move.

Probably, it would likely make the roads slightly safer. However, there are many highly intelligent people out there who lack common sense, which is just as dangerous. It depends on which part of the brain was affected, in regards to your friend. If someone has brain damage, it does not always affect their cognitive processes, so it really depends on the individual's mental state.

I believe that's information their physician would have access to and would put on the paperwork necessary to get a licence. Doctor's call.
