Weigh stations are crucial checkpoints for trucks, but many drivers may not fully understand their purpose. Weigh stations are designed to ensure trucks are compliant with weight and size regulations, preventing accidents and damage to roads.
Most states have designated weigh stations where trucks are required to stop and be weighed. These stations are typically located near major highways and interstates.
To avoid fines and penalties, truck drivers must be aware of the specific regulations in their state. For example, in some states, trucks are required to stop at weigh stations every 50 miles, while in others it's every 100 miles.
Weigh stations can be intimidating, especially for new drivers, but understanding the process can make it less daunting. By knowing what to expect, truckers can navigate these checkpoints with ease.
What Are Weigh Stations?
Weigh stations are crucial checkpoints for trucks, and understanding their purpose is essential for truckers and anyone interested in the trucking industry. Weigh stations ensure that commercial vehicles are following laws and safety guidelines set by the state.

Trucks that are over the prescribed weight limit can cause significant damage to roads, which can be expensive for the state to repair. A truck that's way over the weight limit can even compromise the safety of highway bridges.
Weigh stations use various methods to determine a truck's weight, including Weigh-in-motion (WIM) systems and portable scales. WIM systems can instantly tell a truck's weight while it's in motion, increasing the chances of being able to skip the weigh station process.
Department of Transportation (DOT) inspections are also conducted at weigh stations. These inspections can be thorough, checking everything from the driver's logbook to the truck's safety features.
Trucks that are overweight may be subject to a safety inspection, where officials check tires, rims, hoses, the kingpin, and other safety considerations.
Here's a breakdown of the different types of DOT inspections that may be conducted at a weigh station:
- Level 1: The most detailed inspection, checking all parts of the vehicle.
- Level 2-6: Less detailed inspections, checking specific parts of the vehicle.
It's worth noting that trucks with an overall weight of under 80,000 pounds are allowed to pass through the checkpoint without any hassle.
Purpose and Function
Weigh stations are essentially checkpoints to ensure there are no overweight vehicles on the road. They also ensure that companies in the trucking industry comply with state and federal laws.
The primary purpose of weigh stations is to determine a truck's gross weight to verify that each commercial vehicle passing through follows the laws and safety guidelines set by the state. This is crucial to prevent damage to roads and bridges, as overloaded trucks pose a significant risk to their safety.
Trucks must weigh 80,000 pounds or less to pass through a checkpoint, as anything over this limit is a risk and cannot go through. This weight limit is in place to prevent damage to roads and bridges.
Taxation is another purpose of weigh stations, as multiple states calculate taxes on transported goods based on how much the cargo weighs. This is an important function of weigh stations.
DOT inspections involve checking every part of the vehicle to ensure it works correctly. These inspections can range from level one to level six, with level six being the most thorough.

Here are some examples of what can be checked during a DOT inspection:
- Low or flat tires
- Tire tread
- Oil, fuel or anti-freeze leaks
- Brake malfunctions
- Broken springs
- Securely mounted fuel tanks
- Cracks in wheels and rims
- Unlocked kingpin
- Hose or tubing leak
Any of these violations can lead to a truck being declared out-of-service, which means it cannot operate until repairs are made.

Truckers' Lingo: Chicken Coop Meaning
Weigh stations can be a real pain for truckers, especially with over 1.6 million heavy-duty truck drivers in America.
The large trucks are forced into a confined space prior to being weighed, which is why some truckers refer to weigh stations as “chicken coops”.
This confined space can cause congestion and waste fuel, making weigh stations a frustrating experience for truckers.
It can cost drivers precious time, which is a valuable resource for anyone on the road.
Types of Stations
Weigh stations are a crucial part of ensuring the safety of roads and highways for all drivers. They exist to prevent overloaded trucks from damaging the roads and bridges.
There are different types of weigh stations, including fixed and portable scales, which are used to measure and record the weight of a truck's axles. DOT officials use these tools to ensure that the load does not exceed the permitted amount.
Safety inspections are another type of weigh station, which involve law enforcement officials ensuring a truck is safe for the roads. They will perform official checks on rims, hoses, tires, brakes, and other crucial components.
Weigh-in-motion (WIM) systems are also used at some weigh stations. These systems use sensors that are able to determine the weight of a truck while it is moving, saving time for both DOT officials and truck drivers.
Here's a breakdown of the types of weigh stations:
- Fixed or portable scales: used to measure and record the weight of a truck's axles.
- Safety inspections: performed to ensure a truck is safe for the roads.
- Weigh-in-motion (WIM) systems: use sensors to determine the weight of a truck while it is moving.
What Are Dot Stations?
DOT stations are essentially weigh stations that ensure commercial vehicles are following state laws and safety guidelines.
These stations play a crucial role in preventing damage to roads by weighing trucks and checking if their weight is within the prescribed limit of 80,000 pounds.
Overweight trucks can cause significant damage to roads and even compromise the safety of highway bridges.
Several states calculate taxes on goods transported based on the weight of the cargo, making weigh stations a vital part of the process.
During a DOT inspection, officials may check the exterior or interior of the vehicle, or both, to ensure everything is in good working order.
They may also review the driver's credentials and other documents to verify their validity.
In some cases, officials may even run tests to identify any signs of drug or alcohol abuse.
