Driving after a concussion can be dangerous as it requires thinking skills that may be impaired by an injured brain. An injured brain makes it harder to think and control a vehicle to identify hazards, and driving could trigger concussion symptoms or issues. There are no clear protocols for returning to driving after a concussion, which can cause confusion. The document advises taking it slow when returning to driving and easing back into it, and to take a break and seek help if symptoms worsen.
