C1+EDifficulty 3/5

If the distance between the centres of the double or tandem axle of a semi-trailer is less than one metre, you should know that the maximum authorised mass of that axle may not exceed:

Correct answer

11 tonnes.

11 tonnes for the two-axle group. Annex IX sets this limit for a trailer or semi-trailer tandem when the axle spacing is less than 1.00 m. Do not confuse it with a single axle or a motor vehicle’s tandem. Any more restrictive technical or authorised limits applicable to the vehicle must also be observed.
