Mar 19, 2026

TLDR To get your Florida driver's license, you must pass a state-mandated drug and alcohol test, officially known as the Traffic Law and Substance Abuse Education (TLSAE) course. This 4-hour requirement for first-time drivers 18 and older is available 100% online from state-authorized providers like DrugAndAlcoholCourse.com for $29.95 plus applicable fees.

What is the Florida Drug and Alcohol Test (TLSAE)?

The Florida "drug and alcohol test" is not a single exam but a mandatory 4-hour educational course called Traffic Law and Substance Abuse Education (TLSAE). This state-required program covers Florida's traffic laws and the dangers of impaired driving, and you must complete it to get your first driver's license if you are 18 or older.This course is a prerequisite set by the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). You cannot schedule your driving test or receive your first license without proof of completion. The good news is that the entire TLSAE course and its final exam can be completed online from home through approved providers, making it a convenient step in the licensing process.
  • Key Requirement: Mandatory for all first-time driver's license applicants aged 18 and over.
  • Course Format: A 4-hour state-approved online course with a final exam.
  • Authorized Provider: You can take the course through Florida's largest online provider, DrugAndAlcoholCourse.com, for $29.95 plus applicable fees.

TLSAE vs. DETS: Which Course Do You Need?

Your age determines which mandatory state course you must take. If you are 18 or older and applying for your first driver's license, you need the 4-hour TLSAE course. If you are 14-17 years old and applying for a learner's permit, you need the newer 6-hour Driver Education Traffic Safety (DETS) course, which replaced the TLSAE requirement for teens as of August 1, 2025.The FLHSMV has different educational pathways for teens and adults. Confusing these courses is a common mistake that can delay your licensing process. Always verify the correct requirement based on your age and license type before enrolling.

How to Complete Your Florida Drug and Alcohol Test: A 3-Step Guide

Completing your TLSAE requirement is a straightforward three-step process that you can do entirely online. First, enroll with a state-authorized provider, then complete the interactive course material at your own pace, and finally, pass the course exam to receive your certificate of completion.
  1. Enroll in a State-Authorized TLSAE Course: Register with an approved provider like DrugAndAlcoholCourse.com. The cost is $29.95 plus any applicable fees, with all costs disclosed upfront and no hidden fees. The course is available in English and Spanish.
  2. Complete the 4-Hour Online Curriculum: Work through the engaging course material, which covers Florida traffic laws and substance abuse education. You can start, stop, and resume anytime with 24/7 access, allowing you to complete it on your schedule.

Common Mistakes That Hurt Your Licensing Progress

Mistake 1: Confusing the TLSAE with the Written Knowledge Test

Many applicants think the "drug and alcohol test" is the same as the DMV's written (Class E Knowledge) exam. They are separate. The TLSAE is a 4-hour educational course, while the written test is a 50-question exam on road rules. You must complete both. Adults (18+) must take the written test in person at the DMV.

Mistake 2: Not Bringing Proof of Completion to the DMV

While providers electronically submit your TLSAE completion to the state, you should always bring your physical certificate to your DMV appointment. This prevents any potential delays if there's a lag in the state's system updating your record.

Mistake 3: Paying More Than Necessary for the Course

The state-approved TLSAE course has a standard market price. As Florida's largest provider, LowestPriceTrafficSchool.com offers the course for $29.95 plus applicable fees, ensuring you get the required education without overpaying.

Conclusion: Your 5-Point Checklist for License Success

  • Verify Your Requirement: Confirm you need the 4-hour TLSAE (age 18+) and not the 6-hour DETS course (age 14-17).
  • Enroll with an Authorized Provider: Register online at DrugAndAlcoholCourse.com for $29.95 plus applicable fees.
  • Complete the Course & Exam: Finish the 4-hour material and pass the final exam at your own pace.
  • Study for the Written Test: Use the official Florida Driver's Handbook and practice tests to prepare for the separate DMV knowledge exam.
  • Gather All Documents: Bring your TLSAE completion certificate, proof of identity, Social Security number, and two proofs of Florida residency to your DMV appointment.
