3 Reasons Trucks Need to Be Weighed

line of trucks that need to be weighedTraveling on the road you have no doubt seen the familiar blinking orange lights with the sign “Weigh Station. All Trucks Must Stop When Lights Are Flashing.” Weigh stations are set up all along the interstates to allow cargo-carrying semi-trucks to check their overall weight. Besides adhering to federal weight regulations, there are various reasons why commercial trucks should absolutely be weighed.


One of the important reasons that trucks must be weighed is safety. The interstates we travel across the country have certain structural limitations. One of those main limitations is weight. These roads have a maximum weight they can handle, and the only vehicles that can come remotely close to those limits are cargo vehicles such as semis. Although weight limits vary by state, federal law dictates trucks must weigh below 80,000 pounds. If a truck is heavier than the restrictions for the road on which they are traveling, it can cause damage over time. The weight limit is usually decided on by several factors including the weight limit of the weakest structural section of that interstate. Weaker spots could be bridges or overpasses, so while the roads can handle more weight, the bridge weight capacity may vary.

Structural road safety is not the only cause for weighing trucks, but also vehicular safety. Cargo trucks are required by law to maintain a load that is within the specified capacities of the truck they are operating. If the truck is overloaded, it presents a danger to both the operator and the other drivers on the road. If a truck has too much weight, it cannot maneuver quickly, is difficult to control going downhill, and need much more space to come to a complete stop.


Another reason trucks must be weighed is to calculate taxes on the truck. Carriers pay thousands of dollars in taxes to put that much stress on the roads, and it is calculated by their load weight. These taxes help maintain the roads and bridges.  Also, if a vehicle is carrying more than the weight restriction, they must split their load or apply for an overweight exception permit at the station before continuing. This is why it is important for carriers to know their weights prior to sending out to avoid any delays or accidents.


At least for business owners, perhaps the most important reason to have commercial trucks weighed is profitability. The value of many goods is largely dependent on weight. Operations managers must calculate the weight of every load shipped and received in an accurate manner to ensure fair trade as well as decrease costs and increase profit. Over a period of time, an inaccurate weight measurement system can cost a company thousands of dollars.

How Does A Truck Get Weighed?

There are various systems that can be used to weight trucks. There are wheel-weighers, concrete decks, portable truck scales, digital scales and more. Each one has its various applications depending on weight limits and whether or not it is a permanent or temporary installation.

Weighing trucks is important for the safety of both the operator as well as others on the road and for business purposes. Looking for a truck scale? Contact Industrial Scale Company for expert advice on which scale system is right for your business or organization.
