Interactive Hengerspill for the theory test

Quick summary for the theory test

  • Payload: The maximum load you can carry in your car or trailer is the permitted total weight minus the kerb weight.
  • License requirements: With a regular driver's license (class B) you can tow a trailer with a permitted total weight of up to 750 kg without any extra qualification.
  • Combination weight: The combined total weight of car and trailer cannot exceed what the car is approved to tow.
  • Skip the table cramming – try the Hengerspill to master the rules intuitively before your test.

Many learner-drivers find loading rules and trailer weight among the hardest topics on the theory test. How much can you actually load? Are you legally allowed to drive with this trailer? With our new interactive Hengerspill the rules become both understandable and logical – without you having to cram boring tables.

How the Hengerspill works

The game puts you into real-life scenarios where you have to make decisions about load and weight. You face two types of challenges: either you have to fill the car and trailer with as much load as possible without breaking the rules, or you are shown an already-loaded situation and have to judge whether it is legal to drive.

After you answer, you see immediately whether you got it right – and why. The game explains exactly which limits apply and where you went wrong, if anywhere.

Two game modes

The Hengerspill varies the tasks so that you have to think fresh every time:

  1. Fill the car – You are given a car with a kerb weight and a maximum permitted total weight. Work from that to find the legal payload.
  2. Fill the car and trailer – Distribute the load wisely between car and trailer without exceeding any of the limits.
  3. Fill the car and caravan – Distribute the load wisely between car and caravan without exceeding any of the limits.
  4. Is this legal? – You are given a fully loaded situation and have to decide whether the combination is within the rules and the vehicle registration document.

Instant feedback

We don't throw you in at the deep end without a life jacket. If you answer wrong, you don't just find out that you got it wrong, but exactly why and what you should have been thinking instead.

Learn from your mistakes

When you slip up, the game shows you exactly which limit you broke and how to calculate correctly. That way you build understanding of the rules instead of just guessing your way through.

Build confidence one task at a time

The more tasks you solve, the more intuitive the rules become. You don't need to memorize tables when you understand the logic behind them. The goal is for you to walk into the theory test with full control over what you can legally load.
