Drunk driving can have severe legal consequences, including prison time. It puts the lives of the driver, passengers, and others on the road in danger. If pulled over by police while intoxicated, it's best not to speak with them without a lawyer as anything you say can be used against you in court. Police have various sobriety tests and tools like breathalyzers to determine if a driver's blood alcohol level is over the legal limit of 0.08%, allowing an arrest.
