Michigan IFTA Rates & Trucking Overview 2026

Michigan's diesel rate of 52.4¢/gal (variable, indexed to wholesale price) is competitive for the Great Lakes region. Detroit is one of the top 5 US freight markets, dominated by automotive parts and finished vehicles — the Big Three (Ford, GM, Stellantis) and hundreds of Tier 1 and 2 suppliers generate enormous just-in-time freight demand. The Ambassador Bridge between Detroit and Windsor, Ontario is the busiest commercial border crossing in North America.

Major Michigan Trucking Routes

I-94 (Chicago–Detroit–Port Huron–Canada), I-75 (Detroit–Flint–Saginaw–Mackinac Bridge–Upper Peninsula), I-96 (Detroit–Lansing–Grand Rapids), I-69 (Lansing–Flint–Port Huron), I-196 (Grand Rapids–Benton Harbor)

Indiana to the south at 53.0¢ is dramatically more expensive — fill up in Michigan before heading south on I-69 or I-94. Ohio at 47.0¢ is also significantly higher. Wisconsin to the northwest at 32.9¢ is modestly higher, and Illinois at 46.7¢ makes Michigan a good fueling state for Chicago-bound runs.

Does Michigan have restrictions for oversized loads?

What's unique about Michigan's automotive freight?
