The law might be written for Local law Enforcement (the Police) to accept a Driver's license, but they aren't enough according to ICE officials in the case of this truck driver.
Truck Driver Arrested Outside Phoenix, Forced to Show Birth Certificate
The man was born in Fresno, CA. He was stopped at a weigh station and asked for his ID. He produced his CDL and they rejected it. They wanted his birth certificate, which his wife had to go home to get and deliver. They try to hide behind saying he didn't have the proper paperwork to have his truck inspected, but why is it that it was only his birth certificate they were after?
