L17 Requirements — What You Need to Drive at 17
Age, documents, parental consent, medical check, and mentor registration. Complete list of requirements for the Czech L17 program.
One missing document and your entire application gets rejected. You go home, book another doctor's appointment, wait two more weeks — and meanwhile your friend who had their paperwork in order is already driving. Unnecessary, because the requirements for L17 are clear and manageable. You just need to know exactly what you need and in what order to arrange it.
This chapter is your complete checklist. We'll cover age requirements, documents, the medical check, mentor registration, and fees. By the time you finish reading, you'll know exactly what to bring to the office, how much you'll pay, and what to watch out for. If you're not yet clear on what L17 actually is and how it works, start with the chapter What Is L17 and How It Works.
Quick summary:
- You can start driving school training from age 15.5, take the exam at the earliest on your 17th birthday
- You need parental consent, a medical certificate (no older than 3 months), and a registered mentor
- The driving school course and exam are identical to the standard license — no L17 surcharge
- Total costs: CZK 17,000–25,000 for driving school + approximately CZK 900–1,200 in fees and the medical check
How Old You Need to Be
This is the question everyone asks first — and the answer is simpler than you'd expect. The entire L17 system is built on three age thresholds, each unlocking the next step.
From 15 and a half years old, you can enroll in driving school and start training. Theory and practical lessons — everything the same as the standard course for eighteen-year-olds. Act No. 247/2000 Coll. (§13) allows you to begin training up to a year and a half before the final exam, so you have plenty of time to get through the entire course at a comfortable pace.
You can take the final exam at the earliest on your 17th birthday. Not a day sooner — the law is precise about this. You must be 17 on the day of the exam, not the day you submit your application. In practice, your driving school will schedule your exam for your birthday or later.
And finally, at 18, your license automatically becomes a full one. No exchange, no additional exam, no office visit. Mentor records are canceled automatically. More about what exactly happens on your eighteenth birthday in the chapter Transition to a Full License.
When to start preparing
The ideal time to enroll in driving school is around your 16th birthday. Training takes several months and you don't want to rush. If you start at 15.5, you'll have plenty of time to go through the course at a comfortable pace and take the exam right on your seventeenth birthday.
What You Need to Qualify
The requirements for an L17 license applicant are practically identical to what any applicant for a category B license must meet. No special test, no additional exam. The law (§83a of Act No. 361/2000 Coll.) adds just a few things related to the fact that you're a minor.
You must complete the full driving school training — and by full, we mean truly full. Act No. 247/2000 Coll. requires 36 teaching hours of theory (in full scope per Annex 3), a minimum of 28 hours of practical driving, 4 hours of first aid training, and 2 hours of vehicle maintenance. Around 70 teaching hours in total. If anyone tells you the L17 course is shorter or easier — they're wrong. It's exactly the same course an eighteen-year-old takes. A detailed step-by-step description of the training is in the chapter Training and Progress.
Then comes the final exam. It consists of two parts: a theory test (you need at least 43 out of 50 points) and a practical driving test with an examiner. You must pass both parts successfully.
Beyond the training and exam, you need three things specific to L17: written consent from your legal guardian (typically a parent), a medical certificate of fitness to drive, and at least one registered mentor. Without any of these, they won't issue your license.
One more formal condition: permanent residence or place of study in the Czech Republic. If you study in Czechia but have your permanent address elsewhere, you can submit the application where you study.
Documents — What to Bring to the Office
When you go to submit your license application, you'll need everything at once. The office won't let you bring half the papers now and the rest next week. So prepare everything in advance.
The foundation is a completed driver's license application — you can get the form at the office or download it online. Attach the certificate of successful exam completion, which is confirmation from the examiner that you passed both theory and the practical test.
Since you're a minor, you need written consent from your legal guardian. A parent (or other legal guardian) must sign consent for you to apply for a license under L17. The consent is signed directly on the application or on a separate form — it depends on the office.
You also need a medical certificate of fitness to drive. It must not be older than three months from the date you submit the application. More on the medical check in a moment.
You'll also need an identity document — your national ID card. If you're a foreign national with permanent residence in the Czech Republic, a passport will do.
And finally, proof of payment of the administrative fee — CZK 200 for issuing the driver's license.
If you want to register a mentor at the same time as your license application (and you definitely should — it's free), add a mentor registration request with the signatures of both the mentor and your legal guardian.
Watch the medical certificate date
The certificate must not be older than 3 months from the date of application. If you get it too early and your exam gets postponed, it could expire and you'll have to visit the doctor again. Schedule your check-up for the last month before your planned exam.
Medical Check
The medical certificate is one of those documents that unnecessarily stresses people out. In reality, it's a routine check-up at your general practitioner (or pediatrician if you're under 19). No specialist, no waiting for a hospital appointment.
The doctor fills out the official form "Medical Certificate of Fitness to Drive Motor Vehicles." They'll check your vision — visual acuity, color perception, and field of vision. They'll check your hearing, musculoskeletal system, and ask about your medical history. They want to know whether you have epilepsy, diabetes, cardiovascular problems, or mental health conditions that could affect your ability to drive.
For most people, the whole check-up takes 15 to 30 minutes and costs CZK 300 to 500. The price varies from doctor to doctor — it's not regulated. You then attach the certificate to your license application.
Since 2026, there's a new development: doctors enter certificates into a digital database. This means you don't need to bring a paper certificate to the office — the clerk can verify your fitness electronically. But keep the paper version just in case.
Mentor — Who Can Be One
The mentor is the key person in the entire L17 program. Without a registered mentor, they won't issue your license, and without a mentor beside you, you can't drive.
The law (§83a of Act No. 361/2000 Coll.) sets clear conditions. The mentor must have held a category B license for more than 10 years. They must have been a continuous holder for the last 5 years. They must not have a single penalty point — zero, none. They must not have a suspended license, and they must not have had a driving ban in the last 5 years.
It doesn't have to be a parent. It can be an uncle, grandmother, older sibling, neighbor, family friend — anyone who meets the requirements. You can have up to 4 mentors at once, so you can alternate between both parents and a grandparent, for example. Initial mentor registration together with the license application is free. If you want to add a mentor later, it costs CZK 100 at the office or CZK 80 online through the Transport Portal.
This is just a brief overview of the conditions. A complete guide to choosing, registering, and the duties of a mentor — including what a mentor may and may not do while driving — is in the dedicated chapter Choosing and the Role of a Mentor.
Foreign mentor
If your mentor doesn't have a Czech driver's license, they must provide a certificate from their home country confirming they meet the conditions (no older than 3 months). Alternatively, a sworn statement with a notarized signature is sufficient.
Where and How to Submit Your Application
You submit the driver's license application at the municipal office of a municipality with extended powers — specifically at the transport department or driver registry. You go to the office based on your permanent address, or if you study elsewhere, based on where you study.
You must appear in person. If you're under 18, the legal guardian signs the consent right there (or brings it with a notarized signature). If you're registering a mentor at the same time, the mentor must either come in person or provide their signature notarized.
Since 2026, there's an alternative — the Transport Portal (portaldopravy.cz). You can submit both the license application and mentor registration electronically. The driver contacts the mentor through the portal, the mentor confirms consent, the legal guardian approves, and the application is submitted without visiting the office. Online services are available for exams taken after January 1, 2026.
Another new feature from 2026: after passing the exam, you can drive for up to 30 days without a physical driver's license. It's enough that you're registered in the driver registry — a police officer can verify it electronically.
How Much Does It All Cost
One of the most common concerns: "L17 is more expensive than a regular license." It's not. The costs are practically identical because the training and exam are the same.
The main expense is the category B driving school course. It'll cost you CZK 17,000 to 25,000, depending on the region and school. In Prague, it can exceed CZK 30,000. Check prices directly with driving schools in your area — on Kvalty.cz we compare them with reviews and pricing.

Total 1066 schools
On top of the course price, add the fees every license applicant pays:
The final exam costs CZK 700. If you don't pass on the first try, retaking the theory is CZK 100 and retaking the practical test is CZK 400. Issuing the driver's license costs CZK 200, and the medical certificate will run you CZK 300 to 500.
What's specific to L17? Initial mentor registration together with the license application is free. If you're adding a mentor later, it's CZK 100 in person at the office or CZK 80 through the Transport Portal. So the total extra cost for the L17 pathway is zero to a few hundred crowns.
How to save
Register your mentor at the same time as your license application — it's free. If you do it later, you'll pay CZK 100 per mentor. And if you're planning multiple mentors, register them all at once.
What You Can and Can't Do — L17 Driver Restrictions
An L17 license puts you behind the wheel, but with clear rules. Before you even start the engine, you need to know where the boundaries are.
With a mentor beside you, you may drive a category B motor vehicle — a passenger car up to 3,500 kg with a maximum of 8 passenger seats. You can attach a trailer up to 750 kg, or heavier if the total combined weight doesn't exceed 3,500 kg. On any Czech road — in the city, on a county road, on the highway. No route or time-of-day restrictions.
An interesting detail: with an L17 license, you automatically gain categories AM (mopeds up to 50 cc) and A1 (motorcycles up to 125 cc, max. 11 kW). And you can ride these on your own, without a mentor. The mentor is required only for category B.
What can't you do? Drive a car without a mentor — under no circumstances, ever, until you turn 18. Drive abroad — the L17 license is valid exclusively within the Czech Republic. Drive with a mentor who isn't registered or doesn't meet the requirements. And drive with a mentor under the influence of alcohol or drugs — that's a violation on the mentor's side, but it will complicate things for you too.
In Czechia, you don't need any sticker or marking on the car. Unlike Germany (mandatory BF17 sticker) and Austria (L plate), Czech L17 requires no vehicle marking. A voluntary "O3" sticker exists but isn't required by law.
What Happens If You Break the Rules
The law also covers situations when things go wrong. Penalties for violating L17 conditions are significant — and you need to know who's responsible for what.
If you're caught driving a car without a mentor, you face a fine of CZK 2,500–5,000 in administrative proceedings and a driving ban for 6 to 12 months. This is a serious offense and the responsibility is yours, not the mentor's. Six months to a year without driving is a very long time for a seventeen-year-old waiting for a full license.
The mentor has obligations too. The law (§83a para. 8) states they must sit beside you, watch the traffic, monitor your driving behavior, and advise you when needed. If they don't comply — say they're sitting in the back seat or not paying attention to traffic — they face a fine of up to CZK 2,500 on the spot, or CZK 4,000–10,000 in administrative proceedings. If they're under the influence of alcohol or drugs, the penalties are significantly higher.
Here's the key thing: the mentor is not responsible for your traffic violations. If you speed, run a red light, or fail to yield, the points and fine go to you — the driver. The mentor is only liable for violating their own duties. And conversely: the mentor doesn't receive penalty points or a driving ban for breaching their mentoring obligations.
A detailed analysis of liability in case of an accident, including insurance aspects, is in the chapter L17 Insurance.
How to Do It — Step by Step
The entire process from the first thought to your first drive with a license looks like this:
Around your 16th birthday, enroll in driving school. Choose one that offers L17 and has good reviews — we'll help you choose in the chapter Driving Schools with the L17 Program or directly on Kvalty.cz. During training, get your medical check-up at your doctor and agree with the mentor (or mentors) who'll drive with you.
You take the exam at the earliest on your 17th birthday. After passing, head to the municipal office with all your documents: application, exam certificate, parental consent, medical certificate, ID card, CZK 200, and the mentor registration request. Everything in one place, in one go.
The office issues your driver's license — and from that moment, you drive. With a mentor beside you, on Czech roads, in real traffic. A year of practice that takes you from a driving school graduate to an actual driver.
Since 2026, it's even simpler
Through the Transport Portal (portaldopravy.cz), you can submit your license application and register mentors electronically. And after the exam, you can drive for up to 30 days even if you don't have the physical license in hand yet — registration in the driver registry is enough.
