COEUR d’ALENE — A man could spend up to 10 years behind bars after police said he drove with a breath alcohol concentration more than four times the legal limit.

Keith B. Nyquist, 42, of Pocatello, is charged with driving under the influence and possession of a controlled substance, both felonies. Previously convicted of two DUIs, Nyquist is also charged with a persistent violator enhancement.

In Idaho, a third DUI conviction within 10 years is punishable by up to 10 years in prison.

Police said they saw a man, identified as Nyquist, “stumble” through the parking lot of a Coeur d’Alene bar and get into a car Tuesday night.

Though Nyquist did not initially start the car or turn the lights on, police said they later spotted the car driving eastbound along Spruce Avenue and initiated a stop.

Police detained Nyquist in handcuffs. He provided breath samples of 0.36, 0.33 and 0.31, according to court documents. In Idaho, a blood alcohol level of 0.08 or more is considered impaired.

A search of the car allegedly yielded a container that held a white substance which police said was meth.

Police arrested Nyquist at the scene.

Nyquist was twice convicted of excessive DUI in 2018 in Valley County, according to court documents. Excessive DUI refers to a blood alcohol level of .20 or higher.

Judge John Cafferty ordered Wednesday that Nyquist be held on $75,000 bail.
