DALTON, WHITFIELD COUNTY (WRCB) – Police in Dalton say they plan to step up DUI enforcement Friday as part of the nationwide "Operation Zero Tolerance".

DPD says they plan to increase random road checks and concentrate patrols in certain areas of the city.

Statistics gathered from the National Highway Traffic Safety Administration over the past 25 years show that, on average, nearly half of all deadly traffic crashes over each year's July 4th holiday involved some level of alcohol. 

In fact, 410 people were killed in motor vehicle traffic crashes nationally during the Fourth of July weekend in 2009.  Of that number, 40 percent involved drivers with a blood alcohol concentration (BAC) of .08 grams per deciliter or higher.

Operation Zero Tolerance will run through the July 4 weekend.
