On August 9–11, 2023, the International Association of Chiefs of Police (IACP) hosted the Impaired Driving and Traffic Safety Conference (IDTS). This conference blended the success of the former Drugs, Alcohol, and Impaired Driving Conference with additional educational content in overall traffic safety. The event delivered high-value training, networking opportunities, on-site exhibitions, and plenary sessions to police officers, traffic safety advocates, prosecutors, toxicologists, and physicians while providing a forum in which to share information, countermeasures, and best practices for reducing drug- and alcohol-impaired driving and improving road safety.
