The document summarizes how policing and impaired driving enforcement has changed over the decades from the 1960s to today. It describes how impaired driving convictions were more difficult to obtain in the past due to limitations in testing technology. It highlights how roadside testing is now standardized using breathalyzers, with automatic license suspensions for any reading over 0.04 and the requirement for a second test to secure a conviction over 0.08. The article also notes how police work has become more complex dealing with issues like drugs, homelessness, and organized crime, with most time spent on prevention rather than reactive enforcement.
