What are the truck weigh stations on the highway?


Weigh stations, which are widespread across highways throughout America, are a crucial component of the trucking sector. But for what purpose do weigh stations serve? The weight of a truck is verified at a weigh station – a specified stop along a highway. State highway patrols or inspectors from the Department of Transportation normally conduct these weight inspections.


Truck scales can be found at weigh stations. Trucks typically stop at older scales to be weighed. In more recent weigh-in-motion devices, vehicles may be weighed as they pass over the scale. Large commercial vehicles and trucks are usually mandated to utilize weigh stations.


How do weigh stations work?


A truck’s weight is checked at weigh stations to make sure it is not overweight and complies with state regulations and safety standards. Typically, a truck’s weight is determined by taking two measurements:


Axle Weight

The weight that is supported by each tandem axle on a truck is known as the axle weight. This is calculated by adding the mass of the tractor or pickup to the total weight of the cargo and trailer after dividing it by the total number of tandem axles.


Gross weight

The total weight of the load, any attached trailers, pickup trucks, tractors, and any additional accessories.


Weighing trucks keeps overweight trucks off of highways that can’t support the huge load, hence truck  stations are crucial. Roads and bridges may sustain permanent damage from trucks that exceed the permitted weight limit. On the basis of weight, many states levy tariffs on transported commodities. Therefore, truck weigh stations are occasionally employed to collect taxes.


Where can weigh stations be found?


In most cases, weigh stations are situated close to a scale house where auditors have their offices, just off the roadway. Weigh stations are frequently seen around ports of entry close to state borders since each state has its own unique set of local rules and safety regulations governing the weight of trucks and commercial vehicles. Additionally, weigh stations may be positioned in traffic jams or locations where goods are delivered or loaded onto vehicles.


Many states also employ portable scales, which enable stations to be set up anywhere that is big enough to accommodate trucks. With the aid of portable scales, DOT and state inspectors can put up seasonal and transitory check sites close to undeveloped routes with heavy truck traffic. Additionally, temporary checkpoints aid in preventing truckers from eluding stations.


When are weigh stations used?

Most states only demand trucks and other commercial vehicles to stop at  stations when their gross weight exceeds 10,000 pounds. Truck drivers should examine the local rules and laws of the states they will be transporting through to find any exceptions to this rule.

Trucks usually get weighed when crossing state lines because weight restrictions differ from state to state. Trucks may also be weighed in some jurisdictions as they leave a cargo loading zone or are about to enter a delivery facility.

The majority of states in the US demand that trucks stop at all accessible weigh stations. Drivers who choose not to stop risk the possibility of being stopped by a state trooper or other law enforcement officer who is frequently stationed near the highway re-entry ramps, issued a ticket, and forced to go back to the scale.

Truck drivers are not obligated to stop at a closed weigh station, which is the norm when there is considerable traffic, such as on weekends or during rush hour.


Truckers can check whether a weigh station is open by the indicator lights and other markings on the station signs.
