Topic 14: Driving with and without a trailer
Topic 14 is the second of the two extra lessons for class B that the FahrSchAusbO (the regulation on driving school training) adds on top of the general material. It's about what makes each type of vehicle different, from a car on its own to a car with a trailer (B96, BE) and the B197 test drive. Once you've got this topic sorted, you know exactly what your licence lets you drive.

What you learn
What topic 14 covers
This is what's on the plan in the lesson, and it's what the theory test (Theorieprüfung) will ask you about.
- What a class B licence covers (cars, and trailers up to 750 kg)
- When you need B96 (a combination of more than 3,500 kg and up to 4,250 kg permitted total weight)
- When you need BE (a trailer of more than 750 kg and up to 3,500 kg permitted total weight)
- What changes when you tow a trailer: speed, braking distance and how the car behaves on bends
- What the B197 test drive makes possible: you learn on an automatic but your licence covers both kinds of car
- The speed limits for a car with a trailer (80 outside towns, 100 with Tempo 100 approval)
- How to load a trailer safely: noseweight, weight distribution and securing the load
The key rules
What you need to know for sure
A lot of the test questions on this topic come back to these points.
Class B: a car on its own and trailers up to 750 kg
Class B lets you drive cars up to 3,500 kg zGM (zulässige Gesamtmasse, the permitted total weight) and tow a trailer up to 750 kg zGM. You can also tow a trailer heavier than 750 kg, as long as the whole combination doesn't come to more than 3,500 kg zGM.
Class B96: combinations up to 4,250 kg
B96 extends class B to combinations with a total weight of more than 3,500 kg and up to 4,250 kg. There's no test. Instead you do a training course of seven hours in total: two and a half hours of theory, three and a half hours of driving exercises and one hour on the road. Your licence then gets the Schlüsselzahl (key number) 96.
Class BE: trailers up to 3,500 kg
BE is a class of its own. It lets you tow a trailer of up to 3,500 kg zGM with a class B car. You only need to pass a practical test, because there's no separate theory test for BE. The minimum age is 17 with BF17, otherwise 18.
B197: learn on an automatic, drive both
Since 2021 you've been able to take your practical test in an automatic. The key number 197 is entered on your licence, but it doesn't restrict anything. After at least 10 lessons in a manual car and a test drive of at least 15 minutes, in which you show your instructor that you can change gear safely, you may drive both automatics and manuals.
Towing: special speed limits
With a trailer, a car may do 80 km/h outside towns, both on country roads and on motorways. If the trailer has Tempo 100 approval (it meets the technical requirements), you may do 100 km/h on motorways and Kraftfahrstraßen (roads for motor vehicles only). The Tempo 100 sticker must be on the back of the trailer.
Common mistakes
Where the test often trips people up
In these places a question often means something different from what it seems to say when you read it quickly.
- Thinking B96 is a separate class
- B96 isn't a class of its own. It's the key number 96, which is added to your class B licence. There's no test, just a training course and a certificate. Afterwards you have to apply to the driving licence office (Straßenverkehrsamt) to have it entered.
- Working out the trailer weight wrongly
- What counts is the zGM, the permitted total weight, not what the trailer actually weighs. You'll find it in the Fahrzeugschein (the registration document) under F.2. If you go over it, you'll be fined and, depending on the case, you may even be driving without a valid licence.
- Thinking B197 only lets you drive automatics
- That's not true. B197 lets you drive both kinds of car. Only drivers who took the automatic-only class B (key number 78) are limited to automatics. B197 is the version that covers both.
- Forgetting the noseweight
- When you load a trailer, put heavy items over the axle where you can. The Stützlast (noseweight), which is the weight pressing down on the tow ball, has to stay within the limits shown in the papers for the car and for the trailer. If it's too low or too high, the combination becomes unstable.

You're driving a car with a trailer on a class B licence. What is the heaviest trailer you may tow?
What is the speed limit outside towns for a car with a trailer that has no Tempo 100 sticker?
What's the difference between B197 and the automatic-only class B (key number 78)?
In the driving lesson
Where you'll meet topic 14 again in the car
We train for classes B, B197, B78, BF17, BE and B96. If you choose B197, you learn and take your test in an automatic, have at least ten lessons in a manual car as well, and finish with a test drive of at least 15 minutes with your instructor. That's not a test, and there's no examiner in the car. The BE test includes hitching and unhitching the trailer and reversing round a corner to the left.
