Most travel is restricted to daylight hours only in Arkansas. Continuous travel may be permitted for heavy haul loads that are not oversize. It is possible under some circumstances to obtain weekend travel permission for some routes/smaller dimensions upon request (when filing).
No travel is permitted when visibility is obstructed, or inclement weather occurs, including—but not limited to—snow, hail, rain, wind, etc. Always follow the instructions on your permit and travel advisories for more information.
