Highway? What are some possible errors that the arresting officer could have done?
In NC its DWI. Yes, perfectly legal to set up a road block if the proper procedures are followed. Cops sometimes refer to it as 'using a net instead of a pole' (some sort of lame fishing analogy I suppose). At a major road block, there is often a swarm of law enforcement (usually state highway patrol troopers) and sometimes even an on site magistrate. Because the 'stopping' element has been removed at a road block, your hopes of slipping through the net due to a mistake being made are less than slim and none However, you should hire an experienced DWI attorney who will check and make sure everything was done properly and get you through the process as easily as possible..
