Sobriety Checkpoints

In Idaho, sobriety checkpoints are illegal under state law.

  • The Idaho courts have ruled that roadblocks designed to deter DUI are not permissible under the state constitution when the police fail to get warrant, lack probable cause to believe a crime is being committed, or lack legislative authority to establish the roadblock. State v. Henderson, 114 Idaho 293, 756 P.2d 1057 (1988).

Case Law

U.S. v. Patzer, 277 F.3d 1080 (2002) -- Police officer who stopped noticed both motorist and passenger appeared to have bloodshot and glassy eyes, and suspected the two were smoking marijuana, did not have probable cause to believe that motorist's ability to drive was impaired, where the motorist's driving and comportment, as described by the officer, did not evidence any impairment. Furthermore, for purpose of Idaho's driving under the influence (DUI) statute, marijuana is a "non-narcotic drug.

State v. Thomas, 318 P.2d 592 (1957) -- Whether driver, who is charged with drunken driving is influenced by liquor solely or by combination with other substances is immaterial.

State v. Lesley, 981 P.2d 748 (1999) -- Evidence that defendant pulled out into roadway and then stopped in traffic lane, failed some field sobriety tests, had distinct injection marks on arm, and took urine test that revealed chemical signature for marijuana and stimulant, was sufficient to sustain conviction of DUI.
