Abstract: 

Much of the emphasis in police and prosecutor training in the area of drunk driving focuses on acquiring the blood or breath test that can be used to prove impaired driving, intoxication, or whatever the legal element of the case. But a very problematic situation is created when an impaired driver is involved in a collision and leaves the scene; now the impairment condition of the alleged driver must be reconstructed from information gathered in the investigation of the collision. This article discusses how to reconstruct the BAC of the driver if the BAC was not recorded at the scene and what factors come into account when calculating it.
