What fraction of fatal auto crashes involve alcohol intoxication?

Explanation:
Alcohol intoxication is a major factor in deadly crashes, and data repeatedly show that a sizable portion of fatal auto crashes involve drunk driving. The best-supported estimate is about one-third, meaning roughly 33 out of every 100 fatal crashes involve alcohol impairment (often defined as a BAC around 0.08% or higher). This figure captures the substantial risk alcohol adds without implying it’s the majority. The other fractions—about a quarter, half, or a tenth—don’t align with the common national statistics, which center around this one-third estimate.
