DETS or TLSAE: Which Florida Course Do You Need?

Your age decides it. Florida changed its first-time driver education requirement on August 1, 2025, and the course that was correct before that date is no longer correct for everyone.

If you are 18 or older, you need the 4-hour TLSAE course, short for Traffic Law and Substance Abuse Education.

If you are under 18, you need the 6-hour DETS course, short for Driver Education Traffic Safety. The TLSAE course will not satisfy the requirement for a teen applicant, even though it did before August 2025.

Buying the wrong one means paying twice, so confirm your age bracket before you enroll anywhere.

What Changed in August 2025

Before August 1, 2025, every first-time Florida driver took the same 4-hour TLSAE course regardless of age. The Florida Department of Highway Safety and Motor Vehicles now requires new applicants under 18 to complete a longer 6-hour DETS course instead.

The TLSAE course did not disappear. It remains the requirement for first-time applicants aged 18 and over, which is why both courses are still sold and still valid, just for different people.

Plenty of older articles and forum answers still describe the pre-2025 rule. If a source tells you a 4-hour course works for a 16-year-old, it is out of date.

Quick Comparison

The Certificate Expires

This catches people who plan ahead, and it is worth knowing before you buy.

A Florida TLSAE certificate is generally valid for one year from the date you complete the course. If you have not used it to apply within that window, it expires and you have to take the course again.

The practical advice is simple: do not complete the course far in advance of when you actually intend to apply. Finishing it a month or two before your licensing appointment is fine. Finishing it eighteen months early means paying for it twice.

What Happens After You Finish

Completing the course does not get you licensed. It makes you eligible to take the Class E Knowledge Exam, Florida's written test.

The exam is 50 multiple-choice questions on traffic laws, road signs, and safe driving practices, drawn from the official Florida Driver's Handbook. You need 80 percent, meaning 40 correct answers, to pass. The first-time failure rate is high, so studying the handbook properly is worth the time.

Your course provider submits your completion electronically to the Florida Department of Highway Safety and Motor Vehicles, but bring your physical certificate to your appointment anyway. Systems occasionally lag, and the certificate resolves it on the spot.

You will also need proof of identity, proof of your Social Security number, and two proofs of Florida residency, plus a vision and hearing screening taken on site.

Frequently Asked Questions

Can a 16-year-old take the TLSAE course in Florida?

No. Since August 1, 2025, applicants under 18 must complete the 6-hour DETS course instead. A TLSAE certificate will not satisfy the requirement for a teen.

How long is the TLSAE course?

Four hours, completed online at your own pace. The DETS course for under-18 applicants is six hours.

Does the TLSAE certificate expire?

Generally yes, one year from your completion date. If you have not applied within that window, you will need to retake the course.

What is the TLSAE course also called?

The drug and alcohol course, the DATA course, or the 4-hour first-time driver course. They all refer to the same Traffic Law and Substance Abuse Education requirement.

Does finishing the course get me my license?

No. It makes you eligible to take the Class E Knowledge Exam, which is the 50-question written test you must pass with 80 percent to move forward.

The Bottom Line

Eighteen and over takes the 4-hour TLSAE course. Under 18 takes the 6-hour DETS course. That split took effect on August 1, 2025, and older guidance describing one course for everyone no longer applies.

If you are 18 or older and applying for your first Florida license, DriverEdToGo offers the 4-hour DHSMV-approved TLSAE course fully online for $16.50, completed at your own pace. Time it within a year of when you plan to apply so your certificate is still valid when you need it.
