The Clay County Sheriff's Office will host a free Teen Driver Challenge course on March 21 to help young drivers improve their safety on the road. The program offers defensive driving instruction and hands-on experience at no cost. This initiative comes as data indicates that between 25% and 30% of teen drivers are involved in a vehicle crash within their first year of eligibility. Participants must have a valid Florida license and have knowledge of vehicle dynamics, human factors, responsibility and liability, and the effects of drugs and alcohol on driving.
