My running mate is a retired Customs Colonel and BP Check points have to be within 100 miles of the boarder and try not answering are you a US citizen? I past BP checks weekly and I know they say here comes that GMC shopping cart again!
As for the original question, the weigh stations are for commercial vehicles. IN NM they will check live stock and lately I have seen check points checking boats for Zebra mussels.
