Allowing a person who has been drinking to get behind the wheel of the car is something that most people will never ever permit. That impaired person is a danger to himself and others, and indeed, to you as well (or at least your pocketbook); laws on the books throughout the country place blame on the party (no pun intended) who allowed a person to drive in such a condition. Why is it then that we are so vigilant about keeping individuals off the road while they’re under the influence of something (drink or drug), but we don’t often think about the other things that can cause impairment, like certain medical conditions.

The fact is a perfectly sober individual can be a danger behind the wheel of any car, if that person suffers from some medical condition. There are many diseases - diabetes, epilepsy, macular degeneration, etc. - which can alter a person’s ability to function and make it impossible for them to safely drive a vehicle; sometimes that’s due to the disease itself, other times because of the medication that they take for their illness.

If you believe that someone you care for is about to drive in an impaired condition, it’s up to you to stop them. Easier said than done, yes, but your responsibility, nonetheless. Here are some tips to help them help themselves.

1. If the person is a diabetic and appears disoriented or sluggish, have them check their blood sugar before getting in the car. A low blood sugar is dangerous for a diabetic, even when they are not driving a car. Offer a soft drink or juice to help them stabilize their blood sugar.
2. For disorientation in people with other health issues, its best to calmly suggest that perhaps someone else should drive.
3. Don’t make any accusations, because that usually backfires.
4. Don’t embarrass them into compliance; make your suggestion in a light (but firm) manner.
5. Let them know that you won’t get into the car with them, if they insist on driving (if you’re going with them, of course). Often that’s enough to get them to hand the keys over, even if it is grudgingly.
6. Hide the keys, then call a cab or make up a couch.

Remember, friends don’t let friends drive impaired.
