Policy Analyses on Underage Drinking Laws

A series of policy analyses have been conducted to identify best practices to reduce underage fatal crashes.  A recent study conducted by Fell and collegues found that  four minimum legal drinking age laws have significant associations with fewer underage drinking-and-driving fatal crashes: possession; purchase; use and lose; and zero tolerance.  In addition, three more general laws were also found to be effective: having a level at 0.08 percent blood alcohol concentration illegal per se law; secondary or upgrade to a primary seat-belt law; and an administrative license revocation law.
