How to read an Oklahoma oversize permit

An Oklahoma OS/OW permit is four pages: details and restrictions on pages 1 and 2, a route map on page 3, and the turn-by-turn Driving Directions on page 4. The start and end are on page 1 under Route Information, with Going To printed before Starting From, so read Starting From first.

Issued by the Oklahoma Department of Transportation through OkiePROS. Written from a real permit we read.

How to read the route

Read the list top to bottom. Each line gives the miles you drive on one road: 'Start on' for the first road, 'Continue onto' for every road after it. The first road name is the main route; names in parentheses are other routes or the town street name on the same stretch, like (US-64, Clarence St). The letters at the end are your direction: WB is westbound, SB is southbound. The miles add up to the Approximate Mileage at the bottom.

Columns, left to right: Miles · Instruction.

Where the route starts and ends

Page 1, under Route Information, gives both ends as a road at a state line: 'Starting From: US-54 @ KANSAS State Line (Inbound)' and 'Going To: US-54 @ TEXAS State Line'. 'Inbound' means you enter Oklahoma there. Going To is printed before Starting From. The same line lists the starting and arrival state and county by number. On page 4 the list simply begins with 'Start on' the first road, and the map on page 3 marks the start A and the end B.

Conditions to watch for

Daylight only

Oversize loads move only from half an hour before sunrise to half an hour after sunset.

“Oversized loads are not allowed movement one half hour after sun down to one half hour before sun up.”

Holidays

No oversize travel on certain holidays. The permit does not list which ones.

“Oversized loads shall not travel on specific holidays.”

Metro rush hours

No oversize moves on Interstates in Tulsa, Cleveland and Oklahoma counties 7-9 AM and 3:30-6:30 PM, Monday to Friday. The 2 miles of I-35 between exits 106 and 108 in Cleveland County are exempt.

“between the hours of 7:00 am & 9:00 am or between 3:30 pm & 6:30 pm”

Signs

Every oversize load needs the regulation OVERSIZE LOAD sign.

“REGULATION OVERSIZE LOAD SIGN REQUIRED FOR ALL OVERSIZE LOADS”

Weather

Travel may be denied in high winds, low visibility, heavy rain, snow, sleet or ice.

“Travel is discouraged and may be denied during periods of inclement weather”

Turnpikes

Turnpikes allow 13'6" wide at most. Wide loads keep right unless exiting left, and stay off the Turner and Will Rogers turnpikes on Fridays from 2 PM to midnight.

“The maximum width on Oklahoma Turnpikes is 13'6".”

City and county roads

You may go up to 5 miles off a city or county road on your permit to get around local restrictions. ODOT suggests calling the city street department or county commissioner first.

“Permit holders are allowed a five (5) mile egress from city or county roads displayed on the permit”

Easy to miss

  • On page 1, Going To is printed before Starting From. Read Starting From first so you do not picture the trip backwards.
  • The Driving Directions never say left or right. Every road change is 'Continue onto', even where you turn. Check the map on page 3 and watch for the next road name.
  • The Miles on each line are for that road only, not a running total. Only the Approximate Mileage line is a total.
  • 'OS/OW: Y / N' at the top reads as oversize yes, overweight no. This permit was charged only the oversize base fee.

Questions

Where is the route on an Oklahoma oversize permit?

On the last page, under Driving Directions. Page 1 only gives the start and end (Starting From and Going To), and page 3 is a map.

Can oversize loads travel at night in Oklahoma?

Not on this permit. Standard Restriction #4 says no movement from half an hour after sundown to half an hour before sunup.

What does WB mean on an Oklahoma permit?

Westbound. Each Driving Directions line ends with your direction of travel on that road: WB for westbound, SB for southbound.

Your permit is the legal document; follow everything it says. Permits change, and yours may differ from the ones we read.Last checked October 2026.
