Metro Police will conduct a sobriety checkpoint from 7 p.m. to 3 a.m. Saturday in the area of Sahara Avenue and Maryland Parkway. The checkpoint will focus on drivers impaired by alcohol or drugs, police said.
In the past 90 days, 23 alcohol- or drug-related violations have been reported in the Sahara corridor, police said.
“This event symbolizes the commitment of the LVMPD toward reducing the number of DUI incidents and decreasing the number of alcohol related traffic collisions as well as alcohol related traffic fatalities,” a Metro statement said.
According to the National Highway Traffic Safety Administration, 7 percent of all traffic accidents involve alcohol.
Police are not legally required to inform the public of checkpoints but do so to increase awareness of impaired driving, according to Metro Police Sgt. Rich Robinson.








"Police are not legally required to inform the public of checkpoints but do so to increase awareness of impaired driving."
I don't believe that statement is correct. I believe they issue these public announcements to get around the 4th amendment regarding illegal searches. Now they can claim it was not an illegal search without probable cause because the checkpoint was publicly announced beforehand.
Somebody with more knowledge please chime in.
Under Nevada Law, Police do not have to notify the public of a Sobriety Checkpoint. Here's a link (from an attorney web page) that gives a good overall explation: http://www.shouselaw.com/nevada/dui/dui-...
