What are Truck Weigh Stations for?

There are truck weigh stations scattered along most major highways in the US, Canada, Taiwan and other countries. Obviously they’re there to weigh trucks, but why do trucks need to be constantly weighed?

Vehicles that weigh more than 26,000 pounds or have 3 or more axles have to pay fuel taxes. Motor homes and other private (non-commercial) vehicles are generally exempt. For example, if you see a race-car team drive by, you’ll often see “not for hire” on the side of the cab. That suggests the vehicle is exempt from the fuel tax charges and keeps other trucking companies from soliciting their services.

Truck weigh stations were originally developed for states to collect the fuel taxes they were owed by the commercial trucks using their roadways. It is similar to the licensing concept that I talked about in a previous post, Why U-Hauls Have Arizona License Plates.

In North America, weight stations aren’t directly used for that purpose anymore. There is now an International Fuel Tax Agreement which allows truckers to file a quarterly tax report. Weigh stations are still used to enforce the tracking and submission of the logs and the payment of the fuel tax.

The scales are still used to enforce weight restrictions. The federal weight restriction is 80,000 pounds. Trucks need a trip permit to transport a load exceeding that weight.

Some weigh stations are pretty high-tech, supporting “weigh-in-motion” technology. This technology can allow truckers to bypass weigh stations entirely. This involves the truck driving over a scale that is built into the right lane of the road, usually about a mile before the weigh station. Depending on the weight of the vehicle, its history and the history of the trucking company, the weigh station operator or an automated system will decide if the truck needs to pull into the weigh station.

Truckers who use these systems have a transponder in their truck, similar to those used for electronic toll collection. If they can skip the weigh station, they will usually get a green light on the transponder. If they need to pull in, they will get a red light.

Weigh stations are also used for safety inspections of vehicles. Truckers often refer to weigh stations as “chicken coops.” Check out my post on trucker signals for more trucker slang.

Locking the Gas Pump Trigger

UPDATE: It is illegal in some places to leave the gas pump while filling your tank. After doing some further research, it appears this is done for two reasons. 1. To prevent you from getting back in your vehicle, which can cause a static buildup that could cause a spark (and fire) when you touch the pump handle again. 2. To ensure you are nearby if the auto-stop fails and fuel begins to spill. So, even if your station provides a locking mechanism, the safest option is to hold the handle while filling.

If you’re like me then you like to lock the fuel pump trigger so you can clean all the garbage out of your car while the tank is filling.

Some gas stations remove the device that locks the trigger so you can’t walk away from the pump while it’s filling. But, there is a secret to locking the trigger without the built-in mechanism: stick your gas cap under the trigger.

That’s it. Now you can do other things while your tank is filling, like tidy your trunk or complain about gas prices with some sucker who is attached to their pump.

Keep an eye on your pump and use this tip at your own risk.
