The purpose is to "stop and arrest alcohol and drug-impaired drivers in our ongoing traffic safety campaign," according to a police announcement.
Driving under the influence is a "deadly crime" that "led to 774 deaths in 2010 because someone failed to designate a sober driver," the department's announcement said. "After falling dramatically for five straight years, figures for 2011 indicate that DUI deaths remained the same as 2010."
"DUI can impact the economy in addition to the pain and suffering of those immediately affected," police said. "Conservatively, a fatality has a $1.4 million impact, an injury $70,000, and a crash that only damages property averages nearly $9,000."
Anyone seeing impaired driving is asked to call 9-1-1 immediately. Police said the following clues may indicate driving under the influence:
• weaving or swerving
• traveling at much slower or much faster speeds
• braking erratically
• remaining at traffic lights once they turn green
• headlights off at night
