Check with the Texas State Police, an authority on this. The test is administered at the scene. Refusal? The person is arrested and hauled before a judge, where the order to draw a blood sample is issued. Blood is drawn immediately to test for alcohol. The assumption is if you were not drinking, and presumably drunk; you would not refuse. It works. The billboards all scream 'Drink, Drive, Go To Jail.' People still drink, but they know what a designated driver is. We need to create another national pastime besides drunk-driving.The start of our 51st year may be a good time to begin.
