From the key facts

  • Height including load max. 4.00 m; width 2.55 m, air-conditioned vehicles with walls at least 45 mm thick 2.60 m (SVG Art. 9 para. 1; VRV Art. 64, 66).
  • Lengths without load: motor vehicles and trailers 12.00 m, articulated vehicle 16.50 m, drawbar combination 18.75 m (VRV Art. 65 para. 1).

Sample questions from this topic

3 of 6 questions free to try. All questions with explanations and the exam simulation are part of the course.

Question 1: What is the maximum height of a vehicle in Switzerland, including the load?

  • 4.20 m
  • 3.80 m
  • 4.00 m
Show answer

Correct answer: 4.00 m

The height of vehicles including the load must not exceed 4 m. 3.80 m is not a legal maximum (at most a signed dimension); 4.20 m is above the maximum.

Legal reference: VRV Art. 66; SVG Art. 9 para. 1

Question 2: Your vehicle complies with all legal maximum values for weight and dimensions. Must it still observe a signed maximum weight?

  • No, the legal maximum values take precedence
  • Only if there is an additional ‘truck’ panel
  • Yes, signed restrictions apply in any case
Show answer

Correct answer: Yes, signed restrictions apply in any case

Signed restrictions on width, height, weight and axle load always remain reserved. Anyone complying with the legal values must therefore still observe a lower signed maximum weight, even without an additional panel.

Legal reference: SVG Art. 9 para. 4; SSV Art. 20 para. 1

Question 3: What is the maximum length of a two-axle bus?

  • 13.50 m
  • 15.00 m
  • 12.00 m
Show answer

Correct answer: 13.50 m

Buses with two axles may be 13.50 m long. 12.00 m applies to other motor vehicles, 15.00 m to buses with more than two axles.

Legal reference: VRV Art. 65 para. 1 let. c
