Florida DMV Drug and Alcohol Course: Requirements, Cost, and Format

If you’re 18 or older and applying for your first driver license in Florida, you have to complete the Florida DMV drug and alcohol course before the state will let you take the written knowledge exam. Officially called Traffic Law and Substance Abuse Education (TLSAE), and sometimes referred to as the DATA course, it runs four hours and covers the physical effects of alcohol and drugs, Florida traffic laws, and the consequences of impaired driving.¹ One important change took effect on August 1, 2025: applicants under 18 no longer take TLSAE and instead complete a newer course called Driver Education Traffic Safety (DETS).

Who Has to Take TLSAE

The requirement applies to anyone 18 or older who has never held a driver license in any state, country, or other jurisdiction. If you moved to Florida with a valid out-of-state license, you’re exempt. So is anyone who completed a Department of Education driver education course through Florida’s public school system.²

Age doesn’t create a shortcut. A 45-year-old who has somehow never been licensed anywhere faces the same requirement as a recent high school graduate. The statute draws one line: have you been licensed before, or haven’t you?

If You’re Under 18

TLSAE no longer applies to minors. Starting August 1, 2025, Florida replaced it with the Driver Education Traffic Safety (DETS) course, which folds substance abuse education into broader driver training content.³

There’s a grandfathering window. Minors who finished TLSAE before August 1, 2025 can still use that certificate, but only for one year after their completion date. Miss that window and the certificate expires, and you’ll need to take DETS from scratch.³ This matters most for 15- and 16-year-olds who took the old course early and then delayed applying for a permit.

Online or Classroom

Most people take TLSAE online. The Florida Department of Highway Safety and Motor Vehicles (DHSMV) approves dozens of internet-based providers, and the full list is published on the department’s website.¹ Some providers also offer app-based versions for phones or tablets. A smaller number run in-person classroom sessions, which the statute requires to be held in distraction-free locations that are reasonably accessible to applicants.²

Stick to the DHSMV’s approved list. Unapproved courses won’t be recognized by the state, and you’ll have no recourse if the completion never posts to your record.

What It Costs

Every provider sets its own tuition, and prices range roughly from $20 to $85 depending on the company and whether you choose online or classroom delivery. On top of that, every student pays a $3 assessment that the provider forwards to the DHSMV’s Highway Safety Operating Trust Fund.² The curriculum is fixed by statute, so the cheapest online option and the most expensive classroom school are teaching the same material.

What the Course Covers

Because the curriculum is set by law, every approved provider teaches the same core topics.² The substance abuse portion explains how alcohol and drugs change the brain’s ability to process information: slower reaction times, narrowed field of vision, impaired judgment about speed and distance. You’ll also learn how Blood Alcohol Concentration works, including how body weight, food intake, and time between drinks affect it.

One area that surprises many students is prescription drug impairment. Florida law makes no distinction between illegal drugs, alcohol, and legally prescribed medication when it comes to impaired driving. A valid prescription is not a defense if the medication affects your ability to drive safely. The course covers this because people often assume that following a doctor’s orders shields them from a DUI charge, and it doesn’t.

The traffic law portion covers Florida-specific rules of the road, defensive driving, and risky behaviors such as speeding, running red lights, and distracted driving. The statute specifically requires instruction on the dangers of using electronic devices behind the wheel.² The course also addresses motorcyclist, bicyclist, and pedestrian safety, along with the broader economic costs that substance abuse imposes on society.

Finishing the Course and What Comes Next

The four-hour course ends with a final exam administered by your provider. Once you pass, the provider submits your completion electronically to the DHSMV, and every driver license office can see the record. Allow 24 to 72 hours for it to post.⁴ You don’t need to bring a paper certificate to the DHSMV office, since examiners pull the record from the system directly. Keeping a digital or printed copy anyway is smart insurance against the occasional database hiccup.

After your completion shows up, your next step is the Class E Knowledge Exam: 50 multiple-choice questions on Florida traffic laws, safe driving, and traffic signs. You need at least 40 correct — an 80 percent score — to pass.⁵ Passing gets you a learner’s license, which you’ll need to hold for 12 months or until you turn 18 before qualifying for a full license.

One boundary worth noting: the TLSAE course is separate from the DUI program substance abuse education course required for reinstating a license after a DUI conviction.⁶ If you’re trying to get a license back after a suspension, TLSAE is not the course you’re looking for.
