Stay up to date with Urges Nationwide Action to Stop Multiple Substance Impaired Driving as National Impaired Driving Prevention Month Begins and U.S. House passes MORE Act

Arlington, Va. — As America kicks off December’s National Impaired Driving Prevention Month, urges Americans to take action to prevent impaired driving — particularly the rising problem of multiple-substance impaired driving, where individuals drive under the influence of a combination of substances that have an exponential and especially dangerous effect on impairment.

This week the United States House of Representatives is expected to pass the Marijuana Opportunity Reinvestment and Expungement (MORE) Act (H.R. 3884), which does not address the issue of impaired driving or underage consumption just as many states have also legalized cannabis without effective countermeasures in place to address these issues.

While traffic-safety advocates and Americans in general have made significant progress in the fight to eliminate impaired driving in the last few decades, the issue of multiple-substance impaired driving has steadily grown as substances have become decriminalized or legalized at a quicker pace than municipalities, police departments and manufacturers have been able to put procedures, training, and equipment in place to effectively measure and address the issue.

“Impaired drivers do not drink alcohol on Monday, consume cannabis on Tuesday, and take impairing medications on Wednesday. More and more, people are driving impaired by three or more impairing substances, which is a national road safety crisis, and we must help people understand the extreme crash risk posed by this behavior,” said Darrin T. Grondel, Vice President of Government Relations and Traffic Safety at

One in three Americans now lives in an area where cannabis consumption is legal. Additionally, greater use of prescription and over-the-counter medications, an ongoing opioid epidemic, and continued challenges with eliminating alcohol-impaired driving create a new and dangerous road risk.

Driving impaired by one substance is dangerous but when substances are combined, there is a multiplicative effect on driver impairment. People who drive under the influence of alcohol and other substances are up to 200 times more likely to be involved in a crash (Shulze et al., 2012; Griffiths, 2014).

Adding to the organization’s industry-leading inventory of resources to help address impaired driving, today announced its formation of the National Alliance to Stop Impaired Driving (NASID), a broad coalition effort to eliminate all forms of impaired driving, especially multiple-substance impaired driving, through DUI system reform, DUI detection, data improvements and technology to effectively fight impaired driving. is sponsoring a December 2 webinar hosted by the National Conference of State Legislatures. The webinar is called “Drunk and High Behind the Wheel: Tackling the Growing Threat of Polysubstance-Impaired Driving” and you can register for it here.

Complementing today’s announcement of NASID, the organization released three new resources designed to tackle the issue of impaired driving as part of’s Stop High-Risk Impaired Driving Program, which can be accessed at supports a comprehensive approach to impaired driving prevention, especially actions to promote accountability and behavior change and broader use of technologies to prevent impaired driving, such as ignition interlocks, oral fluid testing, monitoring and detection technologies.
