Make an ADHD driver medicated, staged and phone-blocked
ADHD drivers are seriously impaired (slower reactions, more crashes, much higher licence-suspension risk). The biggest single lever is taking stimulant medication while driving and avoiding alcohol; back it with graduated licensing, a physical phone-block that activates with the engine, and small engagement tricks like a manual transmission.

Driving is one of ADHD’s high-risk domains: slower reaction time, more collisions and citations, and roughly triple the licence-suspension risk in the first decade. Because the baseline impairment already resembles intoxication, the interventions that work are about removing risk rather than urging more care.
The single most effective measure is to take stimulant medication while driving and to avoid alcohol entirely — stimulants substantially cut collisions, traffic problems and speeding tickets, and even low-dose alcohol is especially dangerous when the brain already drives as if impaired. Around that, stage independence with graduated licensing: months of supervised daytime driving, then supervised nighttime, then solo, and only much later peers in the car. Distraction has to be removed, not forbidden — telling an ADHD teen not to use their phone fails, so block it physically with an app or an in-car device that disables the phone when the engine starts. Smaller engagement tricks help at the margin: a manual transmission keeps the driver more physically involved (constant shifting and braking), which raises attention to the road.
