What is the maximum speed limit for commercial vehicles on interstates in Arkansas?

The maximum speed limit for commercial vehicles on interstates in Arkansas is generally set at 65 mph unless otherwise posted. This limit is established to ensure safety while allowing for efficient transportation of goods and services. Speed limits are particularly important for larger vehicles, such as trucks and buses, which have different handling and stopping capabilities compared to passenger vehicles. Higher speed limits can increase the risk of accidents, especially given the size and weight of commercial vehicles. It is also vital for drivers to be aware of posted signs as certain sections may have different speed limits due to road conditions or construction. Understanding these regulations helps ensure compliance and promotes safer travel for all motorists on the highway.
