Intoxalock Endorses Safe Driving During "National Impaired Driving Prevention Month" News provided by Share this article Share this article DES MOINES, Iowa, Dec. 21, 2020 /PRNewswire/ -- Earlier this month, Senators Dianne Feinstein (D-Calif.) and John Cornyn (R-Texas) marked December as "National Impaired Driving Prevention Month" to help raise awareness about alcohol and drug impaired driving. Intoxalock, a leading provider of ignition interlocks, announces their endorsement of this initiative. Every December since 1981, the U.S. President proclaims December to be National Impaired Driving Prevention Month. The National Highway Traffic Safety Administration (NHTSA) routinely notes an increase in impaired driving during the month of December. It is a month filled with social events, travel, and opportunities to drink for many people. This has translated into alcohol-related driving offenses, injuries, and fatalities.
