Uber Use Cuts Drunk Driving Accidents in Some Cities

19154746
Use of Uber has contributed to a decrease in drunk driving accidents in some cities but not others, according to HealthDay . Study author Christopher Morrison of the University of Pennsylvania said the availability of public transportation is one factor that may influence Uber’s effect on drunk driving. The findings appear in the American Journal of Epidemiology . The study looked at car crash histories and Uber availability between 2013 and 2016 in Reno and Las Vegas, Nevada; Portland, Oregon; and San Antonio, Texas. Alcohol-involved crashes were reduced by about 60 percent in Portland, but not at all in Reno, the researchers found. “The differences could be due to a wide range of different factors,” Morrison said. “One likely explanation is that local populations use public and private transport differently from city to city, and probably also use ride-sharing services differently from city to city.” He noted that Portland has...

Canadian Teens Admit to Riding With Driver Who Had Been Drinking

Car-keys-and-a-shot-glass
A new study finds more than 35 percent of Canadian high school students admit to having been in a car with a driver who had been drinking, while 20 percent reported ever riding with a driver who had been using marijuana. “These numbers are concerning,” said study author Leia Minaker of the University of Waterloo. “A significant proportion of car-crash deaths are related to alcohol and drug impairment.” The findings come from a national survey of almost 25,000 students, HealthDay reports. The survey found 9 percent of students in grades 11 and 12 have driven within an hour of drinking. More than 9 percent have driven after having used marijuana. The findings are published in the Canadian Medical Association Journal Open .

Requiring Ignition Interlocks for Drunk Drivers Reduces Alcohol-Related Crash Deaths

Requiring Ignition Interlocks for Drunk Drivers Reduces Alcohol-Related Crash Deaths
A new study finds states that require people convicted of drunk driving to install ignition interlock devices in their vehicles have lower rates of alcohol-related crash deaths compared with states that don’t require the devices. States with the interlock requirements had a 15 percent decrease in drunk driving-related deaths, compared with states that did not have laws requiring DUI offenders to use ignition interlocks, Reuters reports. “We were able to see a real improvement in states that require them for all drunk driving convictions,” said lead author Elinore J. Kaufman of the University of Pennsylvania. “Between 2004 and 2013 more than 900 lives were saved, and if every state had this law it would be 2,600 lives.” The study appears in the American Journal of Public Health. A report released last month by Mothers Against Drunk Driving (MADD) concluded ignition interlock systems in cars have prevented 1.77 million attempts at...

Ignition Interlock Systems Have Stopped 1.77 Million Attempts at Drunk Driving

Ignition Interlock Systems Have Stopped 1.77 Million Attempts at Drunk Driving
Ignition interlock systems in cars have prevented 1.77 million attempts at drunk driving since 1999, according to a new report by Mothers Against Drunk Driving (MADD). The report, released Wednesday, is based on data from the 11 major manufacturers of ignition interlock systems, the Associated Press reports. Ignition interlock devices are wired into vehicles. A person convicted of drunk driving must blow into the device to determine their blood alcohol concentration. The device has a preset level for blood alcohol concentration. If a person blows into it when they are over the set limit, the vehicle will not start. The report found ignition interlocks have prevented 1.77 million attempts by a driver to drive with an illegal blood alcohol concentration of .08 or higher, which is legally considered drunk driving in all states. The system sends a signal back to the manufacturer with the results, which allows them to keep...
