What Carriers Should Know

Running Freight Through Wyoming

High Wind Closures on I-80

Wyoming's I-80 corridor, particularly near Laramie and Elk Mountain, is known for sustained high winds strong enough to tip over high profile trailers and trigger road closures. Carriers running I-80 should check wind advisories as closely as weather forecasts before departing.

Ports of Entry on Major Interstates

Wyoming checks weight, registration, and IFTA credentials at fixed ports of entry along its interstate system. Given how sparse the state's population is, enforcement is concentrated on I-80, I-25, and I-90, and carriers should keep paperwork current before crossing in.

Long Distances Between Services

Wyoming's open, high elevation terrain means long stretches between fuel stops, repair shops, and even cell coverage, particularly off the main interstates. Carriers should fuel up early and plan stops in advance rather than assuming services will appear when needed.

IFTA and Trucking in Wyoming: What to Know

Wyoming's trucking network runs along I-80, I-25, and I-90 across wide open, high elevation terrain where wind, not just snow, is one of the biggest operational risks. Sustained high winds regularly close sections of I-80, especially near Laramie and the notorious stretch by Elk Mountain, and energy sector freight adds steady heavy-load traffic to a state with one of the lowest populations and fewest services per mile in the country.

IFTA Filing for Wyoming Miles

Wyoming participates in IFTA like every other member jurisdiction, so a carrier based elsewhere reports Wyoming miles and any fuel purchased in state on their regular quarterly return through their base state rather than filing separately with Wyoming. Because Wyoming's interstates carry a lot of long-haul freight moving between the West Coast and the rest of the country, Wyoming miles show up often even for carriers who aren't specifically targeting the state, so accurate mileage tracking through here matters for a clean quarterly return.

Ports of Entry and Highway Patrol

Wyoming operates fixed ports of entry along I-80, I-25, and I-90 where weight, registration, and fuel tax credentials get checked, positioned to catch the bulk of the state's interstate freight traffic.

The Wyoming Highway Patrol also runs mobile enforcement across the rest of the state, and given how few alternate routes exist once you're off the interstate system, carriers should keep credentials current since there's often no way around a check.

Wind Restrictions and Energy Sector Freight

High wind is a defining hazard on Wyoming's I-80 corridor, and sustained gusts near Laramie and Elk Mountain regularly trigger restrictions for high profile vehicles, including empty trailers and light loads that catch wind more easily than a fully loaded rig.

Wyoming's energy sector, including oil, gas, and wind farm construction, also generates steady heavy and oversize load traffic, and carriers hauling this kind of freight should confirm permit requirements through the Wyoming Department of Transportation before the trip.

Wind, Winter Weather, and Long Distances

Wyoming combines two serious weather risks: sustained high wind capable of tipping over high profile trailers, and winter storms that can drop temperatures and visibility fast at the state's elevation. The stretch of I-80 near Elk Mountain and Laramie is infamous among drivers for both, and closures here aren't rare exceptions during active weather. Add in the long distances between towns and services across the state, and carriers running Wyoming's interstates should treat fuel, weather, and wind planning as one connected decision rather than three separate checks.

“Elk Mountain has taught me to respect wind advisories the same way I respect ice. An empty trailer up there in a gust is no joke at all.”

“The distances out here mean you plan differently. I fuel up way before I need to, because the next stop might be farther than it looks.”

Frequently Asked Questions

Yes. This is the Special Diesel rate IFTA Inc. published for the third quarter of 2026 (July through September). IFTA sets rates every quarter, so confirm the current figure at iftach.org or with your base state before filing.
It happens regularly enough that carriers should check wind advisories before every trip, not just in bad weather. The stretch near Laramie and Elk Mountain is especially prone to closures for high profile vehicles during sustained high winds.
No. Wyoming's interstates are toll-free, though carriers should still expect to stop at fixed ports of entry along I-80, I-25, and I-90 for weight and credential checks.
