Reading that article, it reads more like the person skipped the weigh station and got pulled over by the highway patrol cop usually at the weigh station. Weigh stations will often have a patrol car sitting by the highway that pulls over anyone speeding or who needs to stop at the weigh station but didn't. So CBP (not ICE) was called by a highway officer.
Still to your point of a state government authority calling the feds because someone they interacted with looked Hispanic.
