Checkpoints will be in effect Friday and Saturday between the hours of 8 p.m. and 3 a.m., Shyy said.
“In 2013, San Francisco had one traffic fatality related to a DUI driver,” Shyy said. “We want to continue our education campaign and look for zero traffic fatalities related to alcohol.”
According to the National Highway Traffic Safety Administration, checkpoints provide the most effective results over any other sort of drunken driving enforcement strategy, while being relatively inexpensive, saving $6 for every $1 spent.
The checkpoints will be in locations where collision and drunken driving statistics are higher, Shyy said.
Drivers arrested for drunken driving can incur penalties such as jail time, fines, fees, drunken driving classes and other expenses that can top $10,000, Shyy said.
