How much is the speed of the snow box car speeding?

On snowy days, the speed limit of box trucks is the same as that of ordinary vehicles. Generally speaking, just look at the speed limit sign on the road.

For example, if the speed limit of the expressway drops to 80km/h in snowy days, then your box truck should not exceed 90 km/h. ..

It's better to slow down on snowy days. Safety first!
