You’re 16 and want to be behind the wheel at 17. Your friends are talking about BF17. Is it real? Is it worth it? And what exactly does it involve?
Yes, it’s real, and for most people it’s absolutely worth it. BF17 — accompanied driving from age 17 — is one of the most popular license models in Germany. Someone who starts early will have thousands of kilometres of real driving experience by their 18th birthday, making them statistically far safer than peers who begin at 18.
This guide covers everything: what BF17 is, when you can start, what the companion requirements are, costs, and how to prepare for the theory exam.
What Is BF17 — Accompanied Driving from Age 17?
BF17 is a special regulation that allows you to obtain a full Class B driving license from the age of 17 — with one restriction: until your 18th birthday, you may only drive with a qualified accompanying person present.
On your 18th birthday, the requirement expires automatically. You drive alone — with a full, unrestricted Class B license and a full year of real driving experience already behind you.
The license itself is permanent and contains no restrictions beyond the 18th birthday. It carries an entry (key number 96) that is removed by the licensing authority upon your 18th birthday, on request.
From What Age Can You Start BF17?
- Training (theory lessons, driving lessons): minimum age 16 years and 6 months
- Theory and practical exam: minimum age 17 years
In practice: if you turn 17 in January, you can start training from the previous July and sit the exam in January.
Who Qualifies as an Accompanying Person?
This is the most critical aspect of BF17, and the rules are strict. Not just anyone can accompany you. The legal requirements:
| Requirement | Details |
|---|---|
| Minimum age | 30 years |
| License held | Class B for at least 5 continuous years |
| Flensburg driving record | Maximum 1 point |
| No driving ban | None in the last 5 years |
| Blood alcohol | 0.0‰ — the companion must not have consumed alcohol |
| Registration | Must be registered by name in the learner’s license document before training begins |
The companion is registered at the road traffic authority / citizens’ office in your license document. Typically up to two companions can be registered — for example both parents.
Important: The companion must be in the vehicle — not necessarily in the front passenger seat, but in the same vehicle and within speaking distance.
Is BF17 More Expensive Than a Regular License?
No — BF17 is generally not more expensive than a standard Class B license. The only additional costs are:
- BF17 registration fee at the authority: approx. €35–50
- Companion registration fee: approx. €15–25
All other costs are identical to a standard driving license:
| Cost item | Amount |
|---|---|
| Driving school (registration, lessons, admin) | €300–500 |
| Eye test | €7–12 |
| First aid course | €25–40 |
| Theory exam | €22.49 |
| Driving hours (20–40 hrs) | €1,200–2,200 |
| Practical exam | €97.57 + instructor fee |
| BF17 registration fees | €50–75 |
| Total | approx. €2,000–3,500 |

The Theory Exam for BF17: Identical to Standard Class B
This surprises many people: the theory exam for BF17 is exactly the same as the regular Class B theory exam. There is:
- No simplified BF17 question catalog
- No separate BF17 questions
- No different difficulty level
30 questions, maximum 10 penalty points, video questions included — everything identical. This also means: you prepare with exactly the same app as any other Class B learner.
Why teenagers often learn the theory faster
Here’s a real advantage of starting early: many 16–17 year olds learn theory faster and retain it better than adults. The brain at this age is particularly receptive to structured factual knowledge. With a good app and daily practice, many are exam-ready in 2–3 weeks.

Driving Hours for BF17: Identical to Standard Class B
The driving lessons are no different either. The mandatory special drives for Class B apply equally:
- 5 hours of rural road driving
- 4 hours of motorway driving
- 3 hours of night driving
All with a licensed instructor and registered training vehicle. Plus the normal driving lessons — typically 20–35 hours in total. Overall duration of training is the same.
What Can You Do With BF17 — and What Can’t You?
Permitted:
- Drive all Class B vehicles (cars up to 3,500 kg, light vans, etc.)
- Drive on all roads — city streets, rural roads, motorways
- Drive at any time of day, including at night
- Drive with the companion on longer trips or abroad
Not permitted:
- Driving without the companion — this is the only restriction
What happens if you’re caught driving without a companion? It’s an administrative offence. You face a fine, points in the Flensburg driving record and in serious cases revocation of the BF17 license. The probationary period can be extended to 4 years.
BF17 and the Probationary License
After passing the practical exam, BF17 holders are subject to the same rules as all new drivers: 2 years on a probationary license (extendable to 4 years for certain violations).
The 0.0‰ alcohol limit during the probationary period applies to everyone — BF17 or not.
BF17 vs. Regular License at 18: Which Is Better?
The data is clear:
Statistical safety advantage: According to the Federal Highway Research Institute (BASt), BF17 holders have significantly fewer accidents in their first year of independent driving than 18-year-old new drivers without BF17 experience. A year of supervised practice makes a measurable difference.
Insurance advantage: Some insurers offer lower premiums for young drivers who can demonstrate BF17 experience.
Timing advantage: Having a license earlier matters for apprenticeships, jobs, university.
Typical BF17 Timeline
If you’re 16 years and 6 months old and starting today:
| Phase | Timeframe |
|---|---|
| Admin (authority, first aid, eye test) | Weeks 1–4 |
| Theory study (app + school lessons) | Weeks 1–6 |
| Theory exam | Weeks 6–8 |
| Driving lessons | Weeks 7–16 |
| Practical exam | Weeks 14–20 |
With consistent preparation, the exam is achievable 3–5 months after starting. Someone who passes theory on the first attempt and has a school with good instructor availability can land at the lower end.

Conclusion: BF17 Is Worth It — If You Approach It Seriously
Accompanied driving at 17 is one of the most sensible license models in Germany. Earlier start, more practice, more safety, statistically fewer accidents. The time and financial investment is the same as a standard license — the output is considerably greater.
The most important first step is the same as for any Class B license: start with the right theory app as early as possible, study consistently and pass on the first attempt.
