Dutch program using in-car alcohol lock cuts drunk driving long after end

> A Dutch program that required drivers to install in-car breathalyzer devices, known as alcohol ignition interlocks, significantly reduced repeat drunk driving—even after the program ended—according to new research from Vrije Universiteit Amsterdam. The study covers the introduction of the Alcoholslotprogramma in 2011 and its termination in 2016, showing lasting behavioral changes among participants despite the program’s cancellation on legal grounds.
