A new study by researchers at the Johns Hopkins Center for Injury Research and Policy and Columbia University finds alcohol-related fatal motor vehicle crashes in the U.S. are much lower among drivers with Canadian licenses than drivers with U.S. or Mexican licenses.
The prevalence of alcohol involvement in fatal crashes was 27 percent for both U.S. and Mexican drivers, and 11 percent for Canadian drivers. Similarly, alcohol impairment was found in 23 percent of U.S. and Mexican drivers and 8 percent of Canadian drivers involved in a fatal crash. Research from other countries finds foreign drivers are at greater risk of crashes than native drivers. In contrast, this study shows that drivers licensed in Mexico and Canada who were involved in fatal crashes in the U.S. had the same or less alcohol impairment than U.S.-licensed drivers. The report is published in the October issue of Injury Prevention and is available on the journal’s website.
“Our findings were unexpected, partly because the substantial cultural differences between the U.S. and Mexico led us to anticipate differences in alcohol-related crashes,” said lead study author Susan P. Baker, a professor with the Johns Hopkins Center for Injury Research and Policy, part of the Johns Hopkins Bloomberg School of Public Health. “We also anticipated that Canadian drivers in U.S. crashes would be similar to U.S. drivers because the rate of alcohol-related fatal crashes is similar within the two countries.” Together, Mexican and Canadian drivers comprise more than 70 percent of all foreign-licensed drivers involved in fatal crashes in the U.S.
As a possible explanation, the researchers speculate that the less prominent role of alcohol in fatal crashes of Canadian-licensed drivers in the U.S. may suggest that a larger proportion of Canadians were traveling on vacation or business, situations that may be less likely to involve alcohol. Crashes at night (when alcohol is more likely to be involved) were also least common among Canadian-licensed drivers. And finally, it is also possible that Canadians are less likely to drive after drinking.
Data for this study came from the Fatality Analysis Reporting System (FARS), a National Highway Traffic Safety Administration database of fatal traffic crashes. Study subjects were drivers aged 16 years or older who were licensed in the U.S., Mexico, or Canada and involved in a crash in the U.S. from 1998 to 2008, which resulted in at least one death. Alcohol involvement was defined as having a BAC of 0.01 g/dl or greater, and alcohol impairment was defined as having a BAC of 0.08 g/dl or higher.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
