Enhanced Penalties for Aggravated DUI

In addition, the offender will be required to pay restitution to the victim.

Commercial Drivers

In addition to other penalties associated with Idaho’s DUI laws, a commercial driver who is convicted of DUI while operating any vehicle will be disqualified from driving a commercial vehicle for at least one year. If, however, the offender was driving a commercial vehicle and transporting hazardous materials at the time, the disqualification period is at least three years. If a commercial driver commits a second DUI while driving any vehicle, the offender will be disqualified from driving a commercial vehicle for life, which may or may not be reduced to 10 years.

What is Idaho’s Dram Shop and Social Host Statute?

Under Idaho law, a person who is injured by an intoxicated person may file suit against the drinking establishment or person who sold or furnished the alcohol if the person causing the injury was under 21 and the seller or provider of the alcohol knew or should have known that the person was underage or if the person causing the injury was obviously drunk at the time the alcohol was sold or furnished and the seller or provider knew or should have known that the person was obviously drunk. This statute does not permit the intoxicated person to file suit for injuries he sustained because of his own intoxication. It also prohibits a person who was a passenger in an automobile driven by an intoxicated person to bring suit against the establishment or person who sold or provided the alcohol. Additionally, this law requires the injured person to notify the establishment or person who sold or furnished the alcohol to the intoxicated person within 180 days from the date of the injury by certified mail that suit will be filed.
