If you drive a truck with a gross vehicle weight of over 3.5 t in a built-up area, can you drive at a speed of 70 km/h once you go past this sign?

In the photo, you are driving along a street in a town, next to a bus stop, and on the right there is sign B-33 "70" - a raised limit in a built-up area. When driving a lorry with a maximum permissible mass of over 3.5 t, you are not allowed to drive at 70 km/h here - answer B.

The Regulation on road signs and signals states that sign B-33 showing a speed limit higher than 50 km/h, placed in a built-up area, applies to a passenger car, a motorcycle and a lorry with a maximum permissible mass not exceeding 3.5 t. A heavier lorry does not belong to this group, so the raised limit does not cover it - the general 50 km/h limit from the Road Traffic Act applies to it, regardless of the time of day; answer C is a trick answer referring to the night-time limit of 60 km/h, which no longer exists and was abolished in 2021. The reason: a lorry has a longer braking distance and a collision with it has more serious consequences, and in a town, where there are stops and crossings, the lawmaker does not want it to speed up. So sign B-33 "70" raises the limit only for lighter vehicles, and you drive at 50 km/h. The raised limit also does not cover vehicles carrying dangerous goods, towing, or carrying people outside the cab, even if they are light vehicles.
