The Palm Springs Police Department will operate a DUI checkpoint Friday night at an undisclosed location.

   Beginning at 9 p.m., and continuing until 2:30 a.m. Saturday, officers will look for signs of alcohol or drug impairment and make sure motorists are carrying a valid driver's license, Sgt. Harvey Reed said.

   The checkpoint is funded by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
