Arkansas Trucking Regulations

Arkansas follows the federal 80,000 lbs GVW limit on interstate highways. The Arkansas Department of Transportation (ArDOT) issues oversize/overweight permits through the Permits Section in Little Rock. Single-trip permits start at $25. Arkansas uses a state bridge formula that is generally consistent with the federal Bridge Formula B. ArDOT operates 10 permanent weigh stations along major corridors including I-40, I-30, and I-49. Mobile enforcement units supplement fixed stations. Overweight penalties in Arkansas are among the steeper in the region — fines can reach $10,000 for willful violations. The state enforces seasonal weight restrictions on certain county roads during spring months when frost heave weakens road surfaces. Arkansas allows 73-foot overall vehicle length for standard tractor-trailer combinations.

Arkansas follows federal HOS regulations without additional state-specific rules. The Arkansas Highway Police (AHP), a division of ArDOT, conducts commercial vehicle enforcement. AHP performs approximately 35,000-40,000 CMV inspections annually at weigh stations and during roving patrols. The state participates in CVSA International Roadcheck and enforcement blitzes. Arkansas has no state-specific short-haul exemptions beyond the federal 150 air-mile radius provision. However, the state does offer an agricultural exemption during harvest season (typically September-November) for vehicles hauling agricultural commodities within 150 air-miles of the source. I-40 from Memphis through Little Rock to Fort Smith sees the highest enforcement activity given its role as a major east-west corridor.

Arkansas requires intrastate carriers to register with the Arkansas Public Service Commission (APSC) for operating authority. The APSC issues certificates for common carriers and permits for contract carriers. Registration fees range from $50-$100. Interstate carriers must maintain valid USDOT numbers and comply with UCR requirements. Arkansas requires all CMVs to undergo annual safety inspections — one of the states that mandates periodic inspections rather than relying solely on roadside checks. Inspections must be performed by authorized stations. The state enforces IFTA and IRP requirements at weigh stations. Arkansas also has specific regulations for lumber and poultry hauling, reflecting the state's major industries — Tyson Foods is headquartered in Springdale.
