Hours of Business

When escorting loads or convoys more than 14’ wide, the following conditions shall apply:

On highways of fewer than 4 lanes, Front and Rear escorts shall be required. Except for superloads and large structures, the rear escort may be eliminated if a warning light is attached to the top of the towing vehicle and to the rear of each load and is mounted no less than 2’ or more than 8’ above the surface of the road.

On highways consisting of 4 lanes or more, a rear escort shall be required for superloads and large structures. All other types of loads shall not require escorting.


A superload is a vehicle transporting a nondivisible load that is either in excess of 150,000 lbs GVW or in which any group or groups of axles exceed the limitations of the regulations.

Police state escorts

Kansas Highway Patrol does not provide escorts.

Escort vehicle requirements can differ significantly by state in terms of mandatory driver qualifications, training, certifications, vehicle weights, obligatory signage/flags/lighting, necessary onboard equipment, and more. The ODS team can provide you with all additional requirements specific to your route.

Operating Times

Overdimensional load movements shall be made during daylight hours: 30 minutes before sunrise until 30 minutes after sunset (unless the secretary finds that an emergency exists, in which case a permit for nighttime movement may be issued for the special condition, as the secretary deems advisable).

Travel for overweight only has no time-of-day restrictions and night movements are allowed.

Oversize or overweight loads may move every day of the year (no holiday restrictions applicable).

Adverse weather

Oversize or overweight loads shall not be transported when visibility is less than one-half mile; when conditions of moderate to heavy rain, sleet, snow, fog, or smoke exist; or when highway surfaces are slippery due to ice, packed snow, or rain.

Restrictions on the movement of some or all oversize vehicles or combinations of vehicles may be temporarily implemented due to wind, weather, road or construction conditions.
