WHITTIER — Police are planning to hold a sobriety and driver’s license checkpoint Friday.

The checkpoint will take place from 7 p.m. Friday to 3 a.m. Saturday in the area of Whittier Boulevard and Philadelphia Street, Whittier police officials said in a written statement.

“Research shows that crashes involving alcohol drop by an average of 20 percent when well-publicized checkpoints are conducted often enough,” according to the police statement.

When possible, officers will, “strive to delay motorist only momentarily,” the statement added.

Funding for the checkpoint is being provided by the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
