There are specific actions that draw the attention of people when you're under the influence. Also, there's a procedure police officers need to follow when trying to arrest you for DUI, this is an example of it:

According to this REPORT, Washington state Sen. Mark Schoesler attempted to drive out of the fairgrounds parking lot but backed into a car behind him, which drew the attention of some bystanders, which contacted law enforcement. 

Ritzville police officers responded and determined Schoesler was showing signs of intoxication, so he was transported to the Adams County Jail to take a sobriety test. He also took a breathalyzer test, which resulted in readings of .14, .139 and .15, when the legal limit in Washington is .08.
