The Florida driver education traffic safety DETS course is for first-time drivers under 18, while the TLSAE course is for first-time drivers age 18 or older. Which one you take depends mainly on your age when you apply, and a rule change on August 1, 2025 made that line clearer.
This guide compares the two courses by age, length, and purpose. It also shows teens, adults, and parents how to choose the correct one and avoid paying for a course the state will not accept.

What is the difference between DETS and TLSAE in Florida?
DETS is a 6-hour course for first-time drivers under 18. TLSAE is a 4-hour course for first-time drivers age 18 or older. Both must be completed before you apply for a Florida license, and your age at the time you apply decides which one the state expects.
The Florida Department of Highway Safety and Motor Vehicles (FLHSMV) says that as of August 1, 2025, people under 18 who have never held a license anywhere must complete a 6-hour DETS course before applying. For adults, the state requires a 4-hour TLSAE course from drivers over 18 who have never held a license.
Side-by-side comparison
| Feature | DETS | TLSAE |
|---|---|---|
| Full name | Driver Education Traffic Safety | Traffic Law and Substance Abuse Education |
| Who takes it | First-time applicants under 18 | First-time applicants age 18 or older |
| Length | 6 hours | 4 hours |
| Purpose | Meet the pre-license education requirement for teens | Meet the pre-license education requirement for adults |
| Substitute | DELAP, or FDOE Traffic Safety Classroom 1900300 or 1900310 | DELAP courses offered by some county school boards |
Because the state sets these hours, no course can legally shorten them. Any provider that promises a faster completion would not comply.
Who has to take the Florida driver education traffic safety DETS course?
Anyone under 18 who has never held a driver license from any state, country, or jurisdiction must take DETS before applying in Florida. That means most first-time teen drivers now start here. A few groups are exempt, including teens who already hold a valid out-of-state license.
FLHSMV lists what the change does not affect. Applicants under 18 with a valid out-of-state license transferring to Florida do not need DETS. The same goes for teens who already held a Florida learner’s license before August 1, 2025.
The course also ties into the learner’s license steps. A teen must be at least 15, have a notarized parental consent form, show proof of DETS completion, pass vision and hearing tests, and pass the Class E Knowledge Exam. For a deeper look at the teen path, read our DETS course guide for teens and parents.
Who has to take the TLSAE course?
First-time drivers age 18 or older take the 4-hour TLSAE course. It covers traffic laws and the effects of alcohol and drugs on driving. You need it only if you have never held a license in any state or country, or no longer have one in your possession.
FLHSMV also uses TLSAE in another case. Drivers under 21 who received a suspension notice for a blood alcohol level of .02 to .05 must complete TLSAE to reinstate a license on a hardship basis.
If you are an adult learning to drive for the first time, our TLSAE course overview explains what to expect. You can also compare options in our adult driver education guide.
What changed on August 1, 2025 for applicants under 18?
Before August 1, 2025, first-time teen applicants could use the 4-hour TLSAE course. Since that date, teens under 18 must take the 6-hour DETS course instead. TLSAE is now meant for applicants 18 and older.
FLHSMV set a grandfathering rule for teens who acted early. Teens under 18 who completed TLSAE before August 1, 2025 can use that certificate for one year after the completion date. If they do not get a Florida license within that year, they must take DETS.
A teen who completes TLSAE on or after that date needs DETS, unless enrolled in an FDOE Traffic Safety Classroom course or a DELAP course. Because this is easy to get wrong, check your exact dates with FLHSMV before you enroll.
Can high school driver education replace DETS or TLSAE?
Yes, in many cases. The Driver Education Licensing Assistance Program (DELAP) is driver education taught in participating high schools. A student who passes a certified DELAP course is exempt from taking a separate DETS or TLSAE course.
According to FLHSMV, the Department of Education curriculum already includes DETS and TLSAE material, so enrolled students skip the standalone class. Not every school offers DELAP.
Parents should call the local school board and ask whether the school participates. If it does not, an online DETS course is the usual route. Our guide to the driver education traffic safety course covers the basics.
DETS pros and cons
DETS gives teens a longer, deeper lesson in traffic laws and safe habits before they ever sit behind the wheel. The tradeoff is time: at 6 hours, it takes longer than TLSAE. It also applies only to under-18 first-time applicants.
Pros
- It meets the state requirement for first-time teen applicants.
- The longer format leaves more room for safe-driving habits, not just rules.
- Providers report completion electronically, so no physical certificate is needed to get a license.
Cons
- It takes 6 hours, two more than TLSAE.
- It does not apply to adults, so an 18-year-old needs TLSAE instead.
- A teen who is not sure about dates or school options may need to confirm them first.

TLSAE pros and cons
TLSAE is shorter and focused on traffic laws and substance awareness, which suits adults who want to meet the requirement and move on to the knowledge exam. The tradeoff is that it is not an option for under-18 applicants who start on or after August 1, 2025.
Pros
- At 4 hours, it is the shorter of the two courses.
- It covers alcohol and drug effects on driving, a topic every new driver should understand.
- Adults can usually fit it around work or school when it is offered online.
Cons
- Teens under 18 generally cannot use it for a new application.
- It does not replace the knowledge exam or the driving skills test.
- It is not a mature driver insurance course.

Which course should I pick?
Pick by your age on the day you apply and your license history. Under 18 and never licensed: DETS. Age 18 or older and never licensed: TLSAE. Already licensed elsewhere or in a school DELAP class: confirm with FLHSMV or your school before you buy anything.
| Your situation | Likely course |
|---|---|
| Age 15 to 17, never licensed | DETS (6 hours) |
| Age 18 or older, never licensed | TLSAE (4 hours) |
| Teen who finished TLSAE before August 1, 2025 | TLSAE certificate usable for one year after completion |
| Teen enrolled in school DELAP driver education | Usually exempt; ask your school board |
| Teen with a valid out-of-state license | Not affected by the DETS change |
If you are a parent, check your teen’s birthday first. A teen who turns 18 before applying moves into the TLSAE group.
How does the Florida driver education traffic safety DETS course fit into getting a license?
DETS is one early step in a longer path. After the course, a teen passes the knowledge exam, earns a learner’s license, logs supervised hours, and later takes the skills test. The course does not replace any of these steps.
FLHSMV says the Class E Knowledge Exam has 50 multiple-choice questions, and a passing score is 40 correct answers, or 80 percent. A teen must also hold the learner’s license for 12 months or until age 18, whichever comes first, and complete 50 hours of supervised driving, 10 of them at night.
DriverEducators.com offers online, self-paced, mobile-friendly Florida courses in English, Spanish, and Portuguese, and reports completions electronically to the state. Parents can pair the course with our teen driver safety tips for practice drives.
What if my ticket is a different issue, like Basic Driver Improvement?
DETS and TLSAE are for first-time license applicants. Basic Driver Improvement (BDI) is a different course for licensed drivers who receive a ticket. If you need BDI, you must act within 30 days of the citation, so do not confuse it with these courses.
FLHSMV explains that drivers must elect BDI within 30 days of the citation date and tell the clerk of court before attending. Rules, eligibility, and fees vary, so confirm details with the clerk and your court. Our traffic school guide walks through the steps.
Our Perspective
We see the same confusion every year: a parent signs a teen up for the course they took themselves, or an adult assumes the teen rules apply to them. The age line is simple, but the dates around August 1, 2025 trip people up. Before you pay for anything, check the FLHSMV pages and, if your teen is in high school, ask the school board about DELAP.
We also encourage families to treat the course as the start of good habits, not just a box to check. A teen who understands why impairment, distraction, and speed matter is better prepared for the first solo drive. Parents can reinforce that by talking through each lesson during practice hours.
Course length is set by state rules, and we follow them. If anyone tells you a first-driver course can be finished faster than required, be cautious. When in doubt, confirm requirements with the FLHSMV, your school board, or your court before you enroll.

FAQ
What are the requirements to take a driver improvement course in Florida?
It depends on the course. For Basic Driver Improvement, you need a non-criminal moving violation and no commercial driver license, and you can elect it once every 12 months or eight times in your lifetime. You must also elect within 30 days of the citation. First-time license applicants take DETS or TLSAE instead, based on age.
How do I sign up for a basic driver improvement course in Florida online?
First, tell the clerk of court in the county where you were cited that you elect BDI, and pay the election fee, within 30 days. Then register with an FLHSMV-approved provider. After you finish, you must take the certificate of completion to the clerk. You can start with our Florida courses page.
Can I complete a TLSAE course online to get my Florida insurance discount?
No. TLSAE is for first-time license applicants age 18 or older and is not an insurance discount course. Florida’s discount option is the Mature Driver course for drivers 55 or older, and each insurer decides the amount. Ask your insurer what it accepts before you enroll.
Can a teen who took TLSAE still get a license after August 1, 2025?
Possibly. Teens who finished TLSAE before August 1, 2025 can use the certificate for one year after completion. After that year, they need DETS. Check your dates with FLHSMV.
