The speed limiter fitted in a lorry of gross vehicle weight rating of over 3.5 tons should limit the maximum speed to:
Show the correct answer
Correct answer
A. 90 km/h.
Explanation
The question is about the speed limiter in a lorry with a maximum permissible mass of over 3.5 t. The limiter allows such a vehicle to reach at most 90 km/h - the answer is A.
The Road Traffic Act requires lorries of categories N2 and N3, that is with a maximum permissible mass of over 3.5 t, to have a type-approved speed limiter that limits their speed to 90 km/h. The value 100 km/h (answer B) applies to buses of categories M2 and M3, and 120 km/h (answer C) does not apply to any of these categories. Note: 90 km/h is a technical limit, not the speed at which you are allowed to drive. A lorry with a maximum permissible mass of over 3.5 t may drive outside a built-up area at no more than 80 km/h on a motorway, an expressway and a dual carriageway with at least two lanes in each direction, and at 70 km/h on other roads.
