Driving under the influence is a public safety hazard that could affect anyone at any given time and location. It is not surprising that law enforcement in Charleston is proactive in their enforcement of DUI laws.
Drivers accused of DUI are innocent until proven guilty beyond a reasonable doubt. Because DUI enforcement is so subjective, South Carolina DUI laws require law enforcement to produce and preserve more evidence than in other areas of the law. As a result, DUI checkpoints allow police officers to collect significant evidence and focus specifically on enforcing drunk driving laws.
