Superload information.
Oklahoma ODOT superload information.

Oklahoma superloads are now all about being in compliance with the statutory regulations defined in OL-1. Anything that is not in compliance with OL-1 is going to need to be thoroughly reviewed by the state engineers and maybe even go through a ODOT approval process.

It is fine to link back to your own website if you are contributing to our community.

  1. What happens when no one answers the Phone 405-522-9060 Option 0. I have been trying for days and no one answers.

    This is the 2nd time I leave a reply, the 1st one got deleted. No one has reached out to me to try and help.

    Howe are we supposed to get help from you?

    • Please pardon the delay Garry. Let me see if I can locate a different number for Oklahoma DOT for you. Here it is: (405)522-9060 and thank you as we’ll update the page. Happy holidays!

      • Nothing we can do here if the Oklahoma DOT is not answering. Try calling highway patrol of scale houses near entry. I suspect this is COVID-19 related.

  2. I have a friend that lives in Arkansas and just sold a road grader and needs to deliver it to Oklahoma City. He has a drop deck lowboy and everything to haul it but does he need a special permit or license to bring it to Oklahoma??

  3. Oklahoma is stupid on its rule of putting an escort up front anything over 80ft long the Escort should be in the rear the driver can see up front of the load the dangerous part is in the rear of the load like tail swing in a turn an escort out front of just a long load is stupid this from a retired driver and now escort

    • We agree this isn’t the best case scenario for most primary routes. While it may apply well towards extremely narrow and windy roads in obscure locations such as the Ouachita Forest area and a few others the primary regulations should not reflect this. This is great information to share with others in order to eventually get this rule changed.

      Good point and thank you Arthur!

    • 2 lane vs 4 lane. After much debate it’s been determined by the higher ups it’s safer for a lead on 2 lane roads. Some of us just roll with it. Hang in there!

  4. Is a permit required on Oklahoma roads where the trailer is 59′-0 but the load is 70′-0?

  5. I would say normal posted truck speed unless specified on the permit.

  6. I would like to know what the maximum height is allowed on Oklahoma interstates. I will have a load that is 13’8″.

  7. Thank you. Hey can you clarify what you mean here? Is 15′ 9″ the maximum legal allowed height now? I can see we need to update this page and will get it started right now infact.


  8. OK Pole Car height is 15’9″ – Spoke to OK DOT directly.
