Running Freight Through Tennessee
Memphis Logistics Hub
Memphis is home to one of the busiest cargo airports and freight hubs in the country, and the surrounding warehouse and distribution network generates steady local and regional truck traffic well beyond what passes through on I-40 alone.
Weigh Stations Along Major Interstates
Tennessee runs fixed weigh stations along I-40, I-24, I-75, and I-81, and the Tennessee Highway Patrol adds mobile enforcement on top of them. Carriers crossing the state on any of its major corridors should expect regular weight and log checks.
Monteagle Mountain Grade
The stretch of I-24 near Monteagle in east Tennessee includes a long, steep grade that has caught out unprepared drivers for decades, with runaway truck ramps in place for a reason. Checking brakes and gearing down early matters here more than on flatter Tennessee routes.
IFTA and Trucking in Tennessee: What to Know
Tennessee sits at the crossroads of several major interstates, with Memphis serving as one of the largest logistics and distribution hubs in the country and Nashville and Knoxville anchoring freight in the middle and east of the state. I-40, I-24, I-75, and I-81 all cross Tennessee, and the mountainous terrain in the east, especially the long grade on I-24 at Monteagle, adds a real driving challenge that flatter western Tennessee doesn't have.
IFTA Filing for Tennessee Miles
Tennessee participates in IFTA the same as every member jurisdiction, so a carrier based elsewhere reports Tennessee miles and any in-state fuel purchases on their regular quarterly return through their base state rather than filing separately with Tennessee. Given how much freight passes through Memphis and along the state's interstate crossroads, Tennessee miles show up often even for carriers that aren't specifically targeting the state, so keeping accurate mileage and fuel logs for pass-through trips matters.
Weigh Stations and Highway Patrol Enforcement
Tennessee's fixed weigh stations sit along its busiest interstates, including I-40 running east to west and I-75 and I-81 in the east, where a large share of the state's through freight travels.
The Tennessee Highway Patrol also conducts mobile enforcement and roadside inspections statewide, and given how many interstates converge in the state, carriers should keep registration, IFTA, and log paperwork current no matter which corridor they're running.
Mountain Grades in East Tennessee
The terrain changes significantly once a route moves into east Tennessee, where I-24 near Monteagle and I-40 through the Cumberland Plateau and toward the North Carolina line include long, sustained grades.
Runaway truck ramps on these grades exist because trucks with worn brakes or the wrong gear have needed them, and drivers unfamiliar with the terrain should check their equipment and downshift early rather than riding the brakes the whole way down.
Seasonal Weather Across the State
Tennessee's weather varies more than its size might suggest. Western Tennessee near Memphis sees hot, humid summers and occasional severe thunderstorms, middle Tennessee around Nashville gets a mix of everything including ice storms in winter, and the mountains in the east can hold snow and fog well after the lowlands have cleared. Carriers running the length of the state in a single trip should check conditions at both ends rather than assuming the weather will be consistent the whole way across.

Carriers Running Tennessee Freight
“Monteagle gets talked about for a reason. I check my brakes every single time before that grade, no matter how many times I've run it before.”
“So much freight moves through Memphis that Tennessee miles show up on my IFTA return almost every quarter, even on runs that aren't headed anywhere near the state.”
