On an urban road, what is the speed limit (in k.p.h) for a commercial vehicle with an all up weight of more than 12,000 kg?

1. Correct answer: 50 k.p.h.- even if there is a road sign permitting to drive at a higher speed.
2. 50 k.p.h.- if there is a road sign permitting to drive at a higher speed, the vehicle is permitted to drive at the speed indicated in the sign.
3. 60 k.p.h.- even if there is a road sign permitting to drive at a higher speed.
4. 60 k.p.h.- if there is a road sign permitting to drive at a higher speed, the vehicle is permitted to drive at the speed indicated in the sign.

WhyA commercial vehicle over 12,000 kg drives no faster than 50 KPH in town, even if a sign allows more. The sign raises the limit for others, not for it.
