The high volume of trucks rolling down North Dakota roads can weigh down highways and law enforcement.
That's why the North Dakota Highway Patrol enforces weight restrictions, and teaches troopers what to look out for.
The class of Highway Patrol recruits we've been following get out in the field to check on semis and trucks, and make sure they're not overloaded.
This has become a big part of troopers' jobs across the state, and especially in oil country.
"Most of the recruits will be stationed out in western North Dakota, and a huge part of their job will be enforcing the weight limits." says Sgt. Mitch Rumple.
These two recruits are learning some of the rules of the road, out in the field.
After much work in the classroom, they are practicing truck inspection training, by doing it for real.
"It's basically moving the scale from one tire to another and getting information and adding them up together." says Ves Marinov/Recruit.
The North Dakota Highway Patrol enforces weight restrictions, and teaches troopers what to look out for before checking paperwork and pulling out the portable scales.
"We look for the bulging of the tires, we look for a truck having trouble getting up to speed..." says Sgt. Rumple.
"When you have a truck that accelerates harder or is blowing too much smoke from the exhaust then, you believe that is probably overweight, pull it over, put it on the scales..." says Marinov.
The recruits are in their second month of classes in and outside of the Law Enforcement Training Academy in Bismarck.
"It can be cold with the wind, but with the action, we stayed pretty warm." says Zachary Schwartz/Recruit.
Hands-on training in all kinds of conditions, that prepares the recruits to keep the roads safe.
"One of the biggest investments we have right now is the infrastructure in the state, it takes a lot of money just to build one mile of highway and the cost and the amount of time that it takes to get highways up to standard." says Sgt. Mitch Rumple.
"We have to make sure the roads stay safe to travel and make it to their destinations, in the same manner they left them." says Zachary Schwartz/Recruit.
"This truck that we weighed was legal." says Ves Marinov.
Sgt. Rumple and the two recruits ended up citing seven overloads Wednesday, that adds up to nearly two thousand dollars in fines.
The truck you saw the recruits weighing was legal.
It weighed around 70-thousand pounds.
The maximum weight allowed on interstate is 80-thousand pounds, unless you have a special permit.
