COEUR d'ALENE, Idaho - Drinking and driving remains one of the most common avoidable causes of death for Americans, thousands are killed each year as a result of DUI crashes.
Law enforcement works hard to find and arrest DUI drivers, often times using field sobriety tests.
But how do you accurately train officers in field sobriety testing?
In north Idaho on Friday, a group of volunteer firefighters became intoxicated in a controlled environment and let the officers go to work.
At least 15 different law enforcement officials from North Idaho, Montana and Washington took part in a DUI wet lab.
It's a concentrated effort for officers to test their skills to determine when someone is really intoxicated.
The point, to be flawless when doing field sobriety testing.
In Washington alone, 50% of all traffic deaths have to do with impaired driving according to police.
