Alabama IFTA Rates & Trucking Overview 2026
Alabama's diesel rate of 29.0¢/gal sits near the national median. The state's trucking economy is anchored by automotive manufacturing — Mercedes-Benz in Vance, Honda in Lincoln, Hyundai in Montgomery, and Toyota nearby generate year-round flatbed and parts freight. Birmingham's I-20/I-65 interchange is one of the Southeast's top distribution hubs.
The Port of Mobile handles over 50 million tons annually including steel, coal, and grain. On I-65 north-south corridors, most drivers prefer to top off in Tennessee or Mississippi depending on direction — both offer lower rates than Alabama.
