Show the correct answer
Correct answer
B. 20 km/h.
Explanation
In the photo, sign D-40 "residential area" stands at the entrance to a housing estate street. You can drive an agricultural tractor with a trailer here at a speed of no more than 20 km/h - answer B.
In a residential area the speed limit for every vehicle and vehicle combination is 20 km/h - regardless of whether you are driving a car, a motorcycle or a tractor with a trailer. Pedestrians there use the whole width of the road and have right of way over vehicles, and children under 7 may be on the road without supervision, so your speed must allow you to stop at any moment. 10 km/h (answer A) is less than the limit, although when children are playing on the road you can and should drive more slowly. 30 km/h (answer C) is the general speed limit for an agricultural tractor, also with a trailer, but in a residential area the lower limit of 20 km/h applies. Remember also that in a residential area parking is allowed only in places designated for it.
