TLSAE Course: What It Is, Who Needs It, and How to Complete It in 2026
Quick Answer
The TLSAE (Traffic Law and Substance Abuse Education) course is a mandatory 4-hour program required by the state of Florida for all first-time driver license applicants. Also known as the Drug and Alcohol Course or DETS course, it teaches new drivers about the dangers of impaired driving, Florida DUI laws, and safe driving practices. The course can be completed entirely online and your completion is reported directly to FLHSMV.
What Is TLSAE?
TLSAE = Traffic Law and Substance Abuse Education. It is a first-time driver requirement established by the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). The course was created to ensure that every new driver in Florida understands the serious risks of driving under the influence of alcohol or drugs before they ever get behind the wheel. The TLSAE course is part of Florida's graduated licensing system. It represents the state's commitment to reducing impaired driving by educating drivers at the very beginning of their driving career.
