Operating Hours, Restricted Travel, and Holiday Restrictions
Drivers with proper permits can operate during daylight hours, seven days a week. Loads not exceeding 90 feet in length are authorized continuous travel if the other dimensions meet legal standards.
Movement is not permitted during inclement weather where the conditions are deemed unsafe.
In addition, secondary highways are restricted to 40mph and may be posted to limit vehicles to lesser weight.
No oversize movement is permitted through the greater Little Rock area from 7-9 am or 4-6 pm on Interstate 30 between mile markers 137-143, Interstate 40 between mile markers 151-155, or at any place on Interstate 630.
A permit can authorize weekend travel for over-dimensional loads on Saturday and Sunday. Mobile homes are prohibited from transit on Sundays. Furthermore, oversize loads cannot travel on New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
Signs, Flags, and Lights Requirements
Signs, flags, and lights may be required when moving oversize loads or superloads for the safety of others on the road. However, the state of Arkansas does not specify light requirements for oversize loads, so light requirements ultimately adhere to federal guidelines.
Signs
“Oversize Load” signs are required on all loads that exceed legal dimensions, except for overweight-only loads.
Flags
Red flags measuring 18 inches square must be placed on the rear corners of all loads that surpass legal width, height, or length.
Obtaining a permit
Single trip permits are one-use and valid for four days. Multiple-trip permits can extend to two adjacent counties and are valid for six days. It’s important to note that annual permits are vehicle-specific. Permit authorizations are issued from the Permit Office and must stay in the vehicle to accompany the annual permit.
