Marijuana-Impaired Driving: A Report to Congress
This report describes the absorption, distribution and elimination of delta-9-tetrahydrocannabinal (THC) the primary psychoactive substance in marijuana, in the body. It contrasts this process with the absorption, distribution and elimination of alcohol in the body, as they are very different processes. The poor correlation of THC concentrations in the blood with impairment is discussed, along […]
Uber May Help Cut Drunk-Driving Crashes, But Not Everywhere
Use of ride-sharing services such as Uber has prompted a drop in drunk-driving accidents in some American cities, a new report suggests. But access to smartphone-connected drivers doesn’t uniformly slash booze-related crashes, researchers found. “Uber seems to affect crashes differently in different cities,” said study author Christopher Morrison. Those differences may depend on specific local […]
Legalizing Recreational Marijuana Could Boost Crash Rates, Safety Group Warns
The Insurance Institute for Highway Safety (IIHS) says that studies by the Highway Loss Data Institute and researchers at the University of Texas at Austin point to an increase in crash risk in states that legalized the recreational use of pot. The Highway Loss Data Institute — which, like the IIHS, is a nonprofit organization […]

Examining the Feasibility of Alcohol Ignition Interlocks for Motorcycles
Impaired driving is a major factor in vehicle crashes and traffic fatalities. The use of alcohol ignition interlocks is growing as a countermeasure to combat the high rate of offender recidivism for Driving While Intoxicated (DWI); however, while there is an increase in interlock use on passenger vehicles to reduce DWI recidivism, there has been […]
Evaluation of Responsible Beverage Service to Reduce Impaired Driving
Despite progress in reducing impaired driving, drivers 21 to 34 years old remain a particularly high-risk group for involvement in impaired-driving-related crashes. In 2014, 21-to 34-year-olds accounted for 42 percent of the impaired drivers (i.e., those with a blood alcohol concentration [BAC] of .08 grams per deciliter [g/dL] or greater) of all ages in fatal […]
Impact of the Legalization and Decriminalization of Marijuana on the DWI System
The legalization and decriminalization of marijuana has received a great deal of media attention across the country, and many States are considering whether they should legalize marijuana for recreational or medical use. States need information about the impacts of laws that legalize or decriminalize the use of marijuana, including its impact on driving safety and […]

Law enforcement, prosecution, adjudication, and toxicology among areas examined WASHINGTON, D.C. – The legalization of marijuana for medicinal or recreational use at the state level has the potential to have downstream effects on the entire impaired driving system. In its first completed research project, the National Cooperative Research and Evaluation Program (NCREP) convened a group […]
High Claims: Legalizing Recreational Marijuana Use is Linked to Increase in Crashes
Legalizing recreational marijuana use in Colorado, Oregon and Washington has resulted in collision claim frequencies that are about 3% higher overall than would have been expected without legalization, a new Highway Loss Data Institute (HLDI) analysis shows. This is HLDI’s first look at how the legalization of marijuana since 2014 has affected crashes reported to […]
