The Route: Montana to Oklahoma

This guide outlines a common and efficient route for commercial truck drivers traveling from Montana to Oklahoma. Note that specific origins and destinations within those states will influence the exact route taken, but this represents a generally optimized path.

The primary Interstate Highways utilized on this route are:

• I-90 East: From Montana, begin on I-90 East. This will take you through southern Montana and into Wyoming.
• I-25 South: In Buffalo, Wyoming, transition onto I-25 South. This highway runs through Wyoming and into Colorado.
• I-70 East: Near Denver, Colorado, take I-70 East for a short duration.
• I-35 South: South of Denver, merge onto I-35 South. I-35 is the primary north-south artery that will carry you through Kansas and into Oklahoma. It connects to Oklahoma City and beyond.

While alternative routes may exist involving US Highways or other Interstates, the I-90/I-25/I-70/I-35 corridor generally offers the best combination of road quality and speed for commercial vehicles. Specific on and off-ramps depend on your final delivery point in Oklahoma.

Compliance & Permits

This route passes through several states, each with specific regulations. Be sure to verify you have all required documentation before departing. The following are examples of possible requirements to look into:

• Kansas Trip Permit (if applicable): If you don't have valid IRP registration listing Kansas, or if you are over dimension or weight limits, you'll need a temporary trip permit. Verify this with the Kansas Department of Revenue, Motor Vehicle Division.
• Oklahoma Fuel Tax Permit (if applicable): Similar to Kansas, check requirements for Oklahoma Fuel Tax Permits if you are not properly registered through IFTA.

Weigh Stations & Ports of Entry:

Be prepared for weigh stations and ports of entry. Common locations along this route include:

• Wyoming Weigh Stations: Expect weigh stations along I-90 and I-25 in Wyoming. Be aware of variable speed limits in work zones and near weigh stations.
• Colorado Weigh Stations: Be prepared for inspection and weigh stations on I-70 and I-25 in Colorado.
• Kansas Weigh Stations: Kansas operates weigh stations along I-35.
• Oklahoma Weigh Stations: Expect weigh stations along I-35 in Oklahoma. Watch for signage indicating whether the station is open.

Risks & Hazards

Blizzard conditions can severely restrict visibility and create hazardous driving conditions, especially in mountain passes. Carry chains and be prepared for road closures.
