Generally, no, although some states (New Mexico being one of them) requires all rental vehicles to stop and check in at any weigh station which serves as a port of entry, although they usually won't have to cross the scales.
If it is larger than 16,000 gross vehicle weight, it does.
Interstate weigh stations require any large truck to stop at the stations when they are open and active. A dump truck qualifies as a large truck that would need to stop.
Some states may require it. Ports of Entry in New Mexico require rental vehicles to stop.
The truck it has more weight behind it.
In most states, no. However, some states may require commercial vehicles with a GVWR of as little as 8000 lbs. to stop at weigh stations.
All commercial trucks are subject to total vehicle weight limits and also weight limits per axle. The scales are there to enforce these weight limits.
Well,the small car weighs less then the dump truck,correct? It's similar to, "Why is it easier to lift a feather then a 20 pound weight?". And,since the dump truck is bigger,it gains more speed from its weight,and once it gets going,it's hard to stop.
The reason that it takes a moving truck a much longer time to stop than it takes a car to stop when the brakes are applied on both is because the truck weighs more. The more mass a vehicle has the longer it will take to stop.
Every heavy duty commercial truck is built to customer specs. Unless you have 2 trucks spec'd the same they are each uniquely different which causes the curb weight to differ from truck to truck. There are 2 ways to get a curb weight for that particular truck. One get the vin number and contact an International dealer and have them print a built sheet. Two is to take the truck along with about $9 to a truck stop and put it on a scale.
I found out how much my truck was by going to the dump, your recipt will have your before and after weight. A truck stop, Hwy weigh station or salvage yard also have scales and could give you an exact weight.
Yes, you can go to the dealer, or save money and stop by a uhaul dealer or truck/trailer accessory store.
It can, yes. If you adjust your method of braking properly to account for the absence of weight, it shouldn't. If you simply slam on your brakes, it often will.
