Length and width – driving licence theory

Laterally/to the sides

  • The load may protrude by a maximum of 20 cm to the sides.
  • The total width may be a maximum of 260 cm (2.6 m).

Example 1

Protruding load, example 1.
This is correct. The load protrudes by a maximum of 20 cm to the sides and does not exceed the width of 260 cm.

Example 2

Protruding load, example 2.
The width of 260 cm is not exceeded, but what makes this prohibited is that the load protrudes 40 cm to the right side.

Example 3

Protruding load, example 3.
No load is sticking out, but the vehicle is wider than 260 cm. This means that it may not be driven on normal roads.

Exceptions to these rules exist, but they are very detailed and rarely applicable.


  • The total length may be a maximum 24 metres.
    • Exception: 25.25 metres is permitted if certain specific requirements are fulfilled.
  • Forward protrusion: Mark.
    • Exception: If the part protruding forward is shorter than 1 metre and it is clearly visible to other road users, it does not need to be marked.
  • Rear protrusion: Mark if the part protrudes by more than 1 metre.

Marking in daylight

  • Flags or similar in clear colours both to the front and rear.

Marking in the dark (or as required by weather conditions)

  • Front: Lamp with white light and white reflectors.
  • Rear: Lamp with red light and red reflectors.
Protruding load length-wise.
This is permitted. The maximum length of 24 metres is not exceeded and as the load protrudes by 3 and 4 metres respectively, it is marked.

Marking when towing

When towing, the tow rope shall be marked if the distance between the vehicles is greater than 2 metres.

The tow rope is clearly marked as it is over 2 metres long.

Marking trailers


  • White reflectors (max 40 cm from the outer edges).
  • White position lamp on trailers wider than 160 cm.


  • Orange lights.
  • Orange reflectors.
