Thanksgiving weekend is one of the busiest travel times of the year. In a combined effort to stop impaired driving, prevent injuries and save lives, the Putnam County Sheriff Deputies will take to the roads. The statewide STOP-DWI Crackdown efforts start tomorrow and will end on December 1st.   Research shows that high-visibility enforcement can reduce impaired driving fatalities by as much as 20 percent. Sobriety checkpoints play a key part in raising awareness about the problem.  Throughout the remainder of the year the Statewide STOP-DWI Crackdown Campaign will also target the Holiday Season in December.
