There is no state-wide prohibition of cell phone use or texting while driving in Idaho. Several municipalities have proposed legislation and the City of Sandpoint passed an anti-handheld cell phone ban while driving within the city limits. (The fine is $10 and it is subject to secondary enforcement.) Idaho does have a “Continuing Distraction Law” (also known as an “Inattentive Driving Law”) which requires police officers to list cell phone or texting as causes for an accident. Apparently, the law is rarely enforced.
