The other issue is that when a warrant is issued on a moving traffic violation, one's right to operate in the state of offense is suspended and many states reciprocate. Thus, it might even be that OP is admitted, but is stopped for some unrelated offense somewhere else and is then arrested because he his right to operate is suspended -- even though he may have a valid license. In that situation, he would be charged locally and not extradited to Utah, even if Utah were to offer to extradite.
