Jeff's accident is ruled to be the result of drunk driving because of the presence of alcohol in his car. However, in the case of all traffic accidents resulting in death, thorough investigations are always conducted, including toxicology reports. Jeff would undergo a mandatory autopsy to determine the exact cause of death and therefore it would be known that he was not intoxicated at the time of the accident.
