Show the correct answer
Correct answer
A. 18.75 m.
Explanation
In the photo, a lorry with a trailer - a classic vehicle combination. The maximum permissible length of a combination made up of a power-driven vehicle and a trailer pulled by it is 18.75 m - answer A.
The Road Traffic Act states that the length of a combination of 2 vehicles must not exceed 18.75 m, and of 3 vehicles - 22 m, except for a combination made up of a motor vehicle and a semi-trailer, whose length must not exceed 16.5 m, and combinations with a motorcycle, a moped or a bicycle, which are limited to 4 m. So you need to distinguish two combinations: a tractor unit with a semi-trailer is 16.5 m (answer C), and a lorry with a trailer - as in the photo - is 18.75 m. The value 22 m (answer B) applies to a combination of three vehicles, for example an agricultural tractor with two trailers. Exceeding these lengths means an abnormal vehicle journey, for which you need a permit; you also check the length of the combination when entering car parks and manoeuvring yards.
