Oh, and the fifth amendment:
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.[1]

They don’t run them as DUI check points but as “License Check Points” since all drivers are required to have their license while driving.
Very polite as they ask “May I see your license please?” but the alcohol detecting flashlight is right at your window edge as you hand it over.
