This study suggests a significant increased risk of a motor vehicle crash after a concussion that may justify a safety warning from clinicians.
It suggests current mitigating efforts are insufficient;
however, driving cessation may be unreasonable since the risk also extends to patients as pedestrians. Instead, clinicians might warn concussion patients to be cautious about prevailing motor vehicle crash risks along with standard anticoncussion campaigns.
In addition, effective care of symptoms might reduce risks after a concussion, such as treating headaches, insomnia, depression and substance misuse. Further strategies might include temporarily reducing traffic exposure by avoiding high-speed trips during adverse late-night hours. Ultimately, an awareness of traffic risk after a concussion may help protect the patient and the community.
