In 2020, traffic fatalities increased sharply (4.6 percent) even as vehicle miles traveled dramatically declined. Research from five East Coast trauma centers showed that nearly one in four of seriously or fatally injured drivers tested positive for multiple categories of drugs. (Source: The National Highway Traffic Safety Administration).

Multiple substance impaired driving is underreported due to challenges in detecting and identifying drug involvement but multiple pilot programs to expand drug testing revealed that significant proportions of drivers with illegal BAC limits also tested positive for drugs. has formed The National Alliance to Stop Impaired Driving (NASID) to provide a strong, collaborative national focus on the growing problem of multiple substance impaired driving. NASID is a coalition dedicated to saving lives, promoting awareness, achieving DUI system reform, improving DUI detection and data, and deploying technology to fight all forms of impaired driving.

What we support:

Our work includes state and federal advocacy efforts, public awareness and education, and state implementation of effective program such as

  • Expanded testing among impaired drivers
  • Training for criminal justice practitioners
  • Toxicology lab capacity improvements
  • Programs to increase likelihood of recovery and reductions in recidivism.
  • Effective identification of multiple substance impaired drivers

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 drugs are up to 200 times more likely to be involved in a crash (Shulze et al., 2012; Griffiths, 2014).
