As a commercial vehicle operator in Arkansas, it is crucial to understand and comply with the state’s Department of Transportation (DOT) regulations. These regulations aim to ensure the safety of both drivers and other road users, as well as protect the integrity of the state’s transportation infrastructure. In this article, we will explore some of the key DOT regulations that commercial vehicle operators in Arkansas need to be aware of in 2023.

Vehicle Weight Limits

One of the primary regulations enforced by the Arkansas DOT is the vehicle weight limits. These limits are in place to prevent excessive wear and tear on the state’s roads and bridges. In general, the maximum gross weight allowed for commercial vehicles operating on Arkansas highways is 80,000 pounds. However, certain exceptions and permits may apply for specific types of vehicles and routes.

Licensing and Registration

All commercial vehicles operating in Arkansas must be properly licensed and registered with the state’s DOT. This includes obtaining the necessary permits and paying the required fees. It is essential to keep all registration documents up to date and readily available for inspection by law enforcement officers.

Vehicle Inspections

Regular vehicle inspections are a crucial part of ensuring the safety and compliance of commercial vehicles. The Arkansas DOT requires all commercial vehicles to undergo regular inspections to ensure they meet the state’s safety standards. These inspections typically include checking the vehicle’s brakes, tires, lights, and other essential components.

Hours of Service

Commercial vehicle operators must comply with the state’s hours of service regulations, which dictate the maximum number of hours a driver can operate before taking a mandatory rest period. In Arkansas, the general rule is that drivers cannot drive for more than 11 hours after 10 consecutive hours off duty. Additionally, drivers must take a 30-minute break after eight hours of consecutive driving.

Hazardous Materials Transportation

Transporting hazardous materials requires compliance with specific regulations to ensure the safety of both the driver and the environment. The Arkansas DOT has stringent rules in place for the transportation of hazardous materials, including proper labeling, handling, and reporting of incidents.

Weight and Size Restrictions

In addition to vehicle weight limits, Arkansas also has regulations regarding the size and dimensions of commercial vehicles. These regulations aim to ensure the safe and efficient movement of traffic on the state’s highways. Commercial vehicles must comply with the maximum height, width, and length restrictions set by the Arkansas DOT.

Electronic Logging Devices

Since 2017, the Arkansas DOT has required commercial vehicle operators to use electronic logging devices (ELDs) to record their hours of service accurately. ELDs help ensure compliance with hours of service regulations and promote safer driving practices by preventing drivers from exceeding their maximum allowable driving hours.

Driver Qualifications

Commercial vehicle operators in Arkansas must meet certain qualifications to legally operate a commercial vehicle. These qualifications include holding a valid commercial driver’s license (CDL) with the appropriate endorsements, passing a medical examination, and maintaining a clean driving record. It is essential to regularly review and update driver qualification files to ensure compliance.


Understanding and adhering to the Arkansas DOT regulations for commercial vehicles is vital for ensuring the safe and legal operation of your business. By staying informed about the latest regulations and keeping your vehicles and drivers in compliance, you can avoid penalties, maintain a good safety record, and contribute to the overall safety of Arkansas’ roads.
