The Signal Hill Police Department will conduct a DUI/Driver's License checkpoint, 8 p.m. to 2:30 a.m., April 30.

Drivers passing through the checkpoint will be checked for signs of alcohol and/or drug impairment and proper licensing. Specially trained officers will be available to evaluate those suspected of driving while drug-impaired, police said.

According to police, those caught driving while impaired can expect jail, license suspension, and insurance increases, fines, fees, DUI classes and other expenses that can exceed $10,000.

"Over the course of the past three years, DUI collisions have resulted in 25 injury crashes harming 20 of our friends and neighbors," said Sgt. Russ Hefte, of the Signal Hill Police Department.

According to the National Highway Traffic Safety Administration (NHTSA), checkpoints have been very effective in reducing deaths caused by impair driving.

"DUI checkpoints have been an essential part of the phenomenal reduction in DUI deaths that we witnessed since 2006 in California," said Christopher J. Murphy, director of the Office of Traffic Safety in a statement. "But since the tragedy of DUI accounts for nearly one-third of traffic fatalities, Signal Hill needs the high visibility enforcement and public awareness that checkpoints provide."

According to the department, funding for the checkpoint is provided to SHPD by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
