Florida requires a substance abuse knowledge test before you can get a learner's permit

Florida's Department of Highway Safety and Motor Vehicles (DHSMV) requires all first-time permit applicants under 18 to pass a Drug and Alcohol Knowledge Test before the permit is issued. This is a separate test from the written permit exam — you must pass both. The test covers the effects of drugs and alcohol on driving ability, Florida's impaired driving laws, and the consequences of DUI convictions.

The test is administered at the same DMV office where you take your written permit exam. You cannot skip it or take it at a different time. If you fail, you can retake it the same day or return another day at no additional cost.

This requirement applies to anyone under 18 getting a learner's permit for the first time. If you are 18 or older, you are not required to take this test, though you still must pass the written permit exam.

Key Takeaways

  • All applicants under 18 must pass the Drug and Alcohol Knowledge Test before receiving a learner's permit in Florida.
  • The test is given at the DMV office on the same day as your written permit exam, with no separate appointment or fee required.
  • The test covers impaired driving laws, the effects of substances on driving, and DUI penalties under Florida law.
  • You can retake the test when ready if you fail, and there is no limit to how many times you can attempt it.
  • Applicants 18 and older do not have to take this test, only the standard written permit exam.

What the test covers and how it is structured

The Drug and Alcohol Knowledge Test is a multiple-choice exam. The exact number of questions and passing score are set by DHSMV, but the test focuses on real Florida law and the documented effects of impaired driving. You will be asked about blood alcohol content (BAC) limits, the signs of impaired driving, the penalties for DUI in Florida, and how drugs and alcohol affect judgment, reaction time, and vehicle control.

The test is not designed to trick you. It tests whether you understand the material covered in the official Florida Drivers Handbook, which is provided free at every DMV office and online at the DHSMV website. Most of the content overlaps with the written permit exam, so studying for one helps you prepare for the other.

You will take the test on a computer at the DMV. The test is proctored — a DMV staff member watches to may support you are not using notes or a phone. You have a set amount of time to complete it, though most applicants finish in under 15 minutes.

How to prepare for the test

The best way to prepare is to read the Florida Drivers Handbook, which covers all the material on the test. The handbook is available free in print at any DMV office and online as a PDF on the DHSMV website. Focus on the sections titled "Impaired Driving" and "Substance Abuse and Driving." These sections explain BAC limits, the effects of alcohol and drugs on driving, and the legal consequences of DUI.

You can also take practice tests online through the DHSMV website or through third-party permit test apps. Many of these apps include questions specifically about drugs and alcohol. Taking practice tests helps you get used to the format and identify areas where you need to study more.

There is no official study guide specific to the Drug and Alcohol test alone, but the handbook is thorough and covers everything you need to know. Spend at least a few hours reading the relevant sections before your test date.

What happens if you fail the test

If you do not pass the Drug and Alcohol Knowledge Test, you can retake it when ready at the same DMV office. There is no fee for retaking it, and you do not need to reschedule or come back another day. You can attempt the test as many times as needed until you pass.

However, if you fail the test, you will not receive your learner's permit that day. You must pass both the written permit exam and the Drug and Alcohol test before the permit is issued. If you fail one or both tests, you will need to study and return to retake whichever test you did not pass.

Some DMV offices allow you to retake a failed test the same day; others may ask you to return the next day. Call your local DMV office ahead of time to ask about their specific retesting policy.

Age requirements and who must take the test

The Drug and Alcohol Knowledge Test is required only for applicants under 18. If you are 18 or older, you do not have to take this test. You will still need to pass the written permit exam, but the substance abuse test is waived for adult applicants.

If you are under 18 and explore for a learner's permit in Florida, there are no exceptions to this requirement. You must take and pass the test before your permit is issued, regardless of your driving experience or prior education.

Documents and information you need to bring

You do not need any special documents for the Drug and Alcohol test itself — it is part of your permit process process. However, you will need to bring the same documents required for your learner's permit process: proof of identity, proof of residency, proof of Social Security number, and a completed process form (HSMV 80039).

Bring the original documents or certified copies. Photocopies are not accepted for proof of identity or residency. If you are under 18, a parent or guardian must be present to sign the process.

The test fee is included in the learner's permit fee, which varies by age. There is no separate charge for the Drug and Alcohol test.

Timeline and what to expect on test day

Plan to spend 30 to 45 minutes at the DMV for your permit process and both tests combined. Arrive early — DMV offices can have long wait times, especially on weekends and after school hours. Bring all required documents and be prepared to wait.

When it is your turn, a DMV staff member will verify your documents and have you complete the process form. You will then take the written permit exam first, followed by the Drug and Alcohol test. If you pass both, your learner's permit will be issued the same day. If you fail either test, you can retake it when ready or schedule a return visit.

Bring a pen and wear comfortable clothing. You cannot bring study materials, phones, or notes into the testing area. The DMV provides scratch paper if you need it for calculations or notes during the test.

Frequently Asked Questions

Can I take the Drug and Alcohol test without taking the written permit exam?

No. Both tests must be passed on the same visit to receive your learner's permit. You cannot take one test and skip the other. If you fail either test, you can retake it the same day, but you must pass both before your permit is issued.

What if I studied the handbook but still fail the test?

You can retake the test when ready at no cost. Review the sections of the handbook you found most difficult, and ask the DMV staff if they can point you to specific topics covered on the test. Many applicants pass on their second or third attempt after focused review.

Do I have to take this test if I already have a driver's license from another state?

If you are under 18 and explore for a Florida learner's permit for the first time, yes, you must take the test. A license from another state does not waive this requirement. However, if you are 18 or older, the test is not required regardless of your prior driving history.

Is the test offered in languages other than English?

The test is available in English and Spanish at most Florida DMV offices. Contact your local DMV office in advance if you need the test in a language other than English to confirm availability.

What is the passing score for the Drug and Alcohol test?

DHSMV sets the passing score, but the exact percentage is not publicly listed. The test is designed so that anyone who has read the Florida Drivers Handbook and understands the material should pass. If you study the handbook thoroughly, you should be prepared to pass.
