Once a Nevada driver arrives at a checkpoint, the driver must stop, answer the police's questions, and comply with their requests. The driver may leave only when the police give the okay. Traveling through a Nevada administrative DUI roadblock without stopping is a gross misdemeanor carrying penalties of up to 364 days in jail, and/or up to $2,000 in fines. But if illegally driving through the roadblock results in death, substantial bodily harm or damage to property in excess of $1,000, the driver faces category B felony charges. The punishment includes one to six (1 - 6) years in prison, and/or up to $5,000 in fines.Depending on the case, the defendant may face drunk or drugged driving charges as well. If a driver sees warning signs of an upcoming DUI checkpoint in Nevada, the driver is allowed to take any legal detour prior to that checkpoint to avoid going through it. But the driver may not make an illegal U-turn or an improper turn in order to escape a roadblock.
