I would check with the OK court to see if there is a warrant. If there is one, it will be enforced in another state. If you are stopped for speeding (or any other minor traffic offense) in MS or another state the officer will run a check for warrants. If that OK warrant come up (and it should) you will be arrested and jailed, then extradited to OK. That is not a process you want to go through. Check on that warrant, and if you have one go to OK to get it taken care of.
