State Police say they plan to conduct a sobriety checkpoint Friday at an undisclosed location in Vermilion Parish.

Troopers are calling the checkpoint a “No Refusal” operation, Troop I spokesman Brooks David said.

Although the public reserves the right — no matter the occasion — to refuse a breath analysis measuring their level of intoxication, troopers plan to secure warrants for either a urine or blood analysis for anyone who refuses the test, David said.

“You have the right to refuse, but if you do, just know we’re gonna go to a judge to get a search warrant or court order,” David said.

Such warrants are approved by a judge only when law enforcement officers can provide probable cause to overcome the individual’s refusal as, for example, if the person fails a field sobriety test, David said.

The checkpoint will be from 9 p.m. Friday to 3 a.m. Saturday.
