[a_summary] => Mandatory breathalyzer tests/ignition locks for DUI offenders led to a 15 percent reduction in drunk-driving related deaths.
[a_article] =>
If you’ve been arrested once for driving drunk, it’s not unlikely you’ll be caught again. The National Highway Traffic Safety Administration reports one-third of the 1.4 million drunk or impaired driving arrests each year involve repeat offenders. This fact alone is compelling evidence that DUI offenders should be required to install an ignition interlock, a simple device that won’t allow a car to start unless the driver first passes a breathalyzer test. New research proves they are effective.
The University of Pennsylvania study finds mandatory in-car breathalyzer tests saved an estimated 915 lives between the years 2007 and 2013. This represents a 15 percent reduction in drunk-driving related deaths compared to states without legislation requiring the ignition locks for DUI offenders, say the researchers.
Dr. Elinore J. Kaufman, lead author of the current study, and Dr. Douglas J. Wiebe, senior author, say accidents involving alcohol lead to 11,000 deaths each year and make up nearly 30 percent of all vehicular fatalities. Their research shows making ignition interlock devices mandatory for repeat DUI offenders would go a long way toward bringing down the numbers of these deaths.
One of the biggest supporters of mandatory ignition interlock devices is Mothers Against Drunk Driving (MADD), an organization founded in 1980 by a mom whose daughter was killed by a drunk driver. According to MADD, the average drunk driver has driven drunk 80 times before a first arrest. MADD also reports that, on any given day, more than two million drunk drivers who have had three or more prior convictions are on the road… with you!
The need to require convicted drunk drivers to prove they are sober before starting a car is evident to mothers and lawmakers in the 22 states where ignition interlock regulations apply to all drunk driving offenders. (All states mandate some use of these devices, with most states requiring them only under certain circumstances, such as a very high level of inebriation at first offense.) MADD estimates these laws have prevented 1.77 million attempts by a driver to drive with an illegal blood alcohol concentration (BAC) of .08 or higher.
To understand whether laws requiring DUI offenders deploy the ignition device have helped, the research duo requested data from the National Highway Traffic Safety Administration. Then, they examined the number of alcohol-related crash deaths in 18 states requiring ignition locks for everyone convicted of a DUI (as of 2013, the most recent statistical year) and compared this to the number of alcohol-related crash deaths in states without mandatory interlocks for all offenders.
Their analysis finds these laws are effective. States with mandatory locked-ignition laws reported the number of lives saved totaled 1 person for every 125,000 each year. This compares to 1 person saved for every 110,000 after airbags became a mandatory safety feature in cars; and 1 person saved for every 500,000 after the drinking age was raised from 17 to 21 years old.
As of 2010, about 300,000 interlock devices were in use nationwide, up from 100,000 just four years before, but they are still only used in about 30 percent of drunk driving convictions, wrote the authors. With faster, more compact designs in development, the authors recommend wide adoption to prevent needless injuries and deaths.

If you’ve been arrested once for driving drunk, it’s not unlikely you’ll be caught again. The National Highway Traffic Safety Administration reports one-third of the 1.4 million drunk or impaired driving arrests each year involve repeat offenders. This fact alone is compelling evidence that DUI offenders should be required to install an ignition interlock, a simple device that won’t allow a car to start unless the driver first passes a breathalyzer test. New research proves they are effective.
The University of Pennsylvania study finds mandatory in-car breathalyzer tests saved an estimated 915 lives between the years 2007 and 2013. This represents a 15 percent reduction in drunk-driving related deaths compared to states without legislation requiring the ignition locks for DUI offenders, say the researchers.
Dr. Elinore J. Kaufman, lead author of the current study, and Dr. Douglas J. Wiebe, senior author, say accidents involving alcohol lead to 11,000 deaths each year and make up nearly 30 percent of all vehicular fatalities. Their research shows making ignition interlock devices mandatory for repeat DUI offenders would go a long way toward bringing down the numbers of these deaths.
One of the biggest supporters of mandatory ignition interlock devices is Mothers Against Drunk Driving (MADD), an organization founded in 1980 by a mom whose daughter was killed by a drunk driver. According to MADD, the average drunk driver has driven drunk 80 times before a first arrest. MADD also reports that, on any given day, more than two million drunk drivers who have had three or more prior convictions are on the road… with you!
The need to require convicted drunk drivers to prove they are sober before starting a car is evident to mothers and lawmakers in the 22 states where ignition interlock regulations apply to all drunk driving offenders. (All states mandate some use of these devices, with most states requiring them only under certain circumstances, such as a very high level of inebriation at first offense.) MADD estimates these laws have prevented 1.77 million attempts by a driver to drive with an illegal blood alcohol concentration (BAC) of .08 or higher.
To understand whether laws requiring DUI offenders deploy the ignition device have helped, the research duo requested data from the National Highway Traffic Safety Administration. Then, they examined the number of alcohol-related crash deaths in 18 states requiring ignition locks for everyone convicted of a DUI (as of 2013, the most recent statistical year) and compared this to the number of alcohol-related crash deaths in states without mandatory interlocks for all offenders.
Their analysis finds these laws are effective. States with mandatory locked-ignition laws reported the number of lives saved totaled 1 person for every 125,000 each year. This compares to 1 person saved for every 110,000 after airbags became a mandatory safety feature in cars; and 1 person saved for every 500,000 after the drinking age was raised from 17 to 21 years old.
As of 2010, about 300,000 interlock devices were in use nationwide, up from 100,000 just four years before, but they are still only used in about 30 percent of drunk driving convictions, wrote the authors. With faster, more compact designs in development, the authors recommend wide adoption to prevent needless injuries and deaths.

The study also revealed that individuals who quit smoking, regardless of age, can achieve a life expectancy similar to non-smokers within approximately 10 years after quitting, and nearly half of this benefit can be noticed within just three years.
Researchers found that a combination of genetics and environmental factors reduces longevity in dementia patients. The same combination may shorten the lives of their siblings even without dementia.
The suicide rates increase substantially when air pollution rises, and the effect was particularly strong in the elderly, with older women 2.5 times more at risk than other groups.
While mental stress is commonly acknowledged in connection with grief, it is crucial to understand that grief can also present physical symptoms, including illnesses, fatigue, pain, and sleep disturbances.
The use of antidepressants, particularly fluoxetine, could affect the development of the prefrontal cortex of the infant's brain, potentially raising the risk of mental health disorders later in their life.
Researchers have developed smart earrings that could continuously monitor a person's earlobe temperature. The innovation known as Thermal Earring could also be potentially used to track signs of ovulation, stress, eating, and exercise.
The researchers made the interesting finding using a trial involving patients with a rare genetic condition called Alpha-1 antitrypsin deficiency (AATD).
People infected with the flu were more likely to need hospital care in the following year for common neurologic conditions than people who had the SARS-CoV2 infection.
Among women with a history of pregnancy complications, those who achieved or maintained high heart health after pregnancy were at a similar risk for heart disease as women without adverse pregnancy outcomes and good cardiovascular health, the study stated.
The study published in the journal BMJ indicated that individuals with hypermobile joints had a 30% higher chance of not fully recovering from COVID-19 and experiencing persistent fatigue associated with long COVID.
The studies showed that COVID antigens lingered in the blood up to 14 months after infection and more than two years in tissue samples of people who had the infection.
Those individuals who receive a COVID-19 vaccine during the first half of their menstrual cycle are more likely to experience cycle length changes than those receiving a vaccine in the latter half.
If you’ve been arrested once for driving drunk, it’s not unlikely you’ll be caught again. The National Highway Traffic Safety Administration reports one-third of the 1.4 million drunk or impaired driving arrests each year involve repeat offenders. This fact alone is compelling evidence that DUI offenders should be required to install an ignition interlock, a simple device that won’t allow a car to start unless the driver first passes a breathalyzer test. New research proves they are effective.
The University of Pennsylvania study finds mandatory in-car breathalyzer tests saved an estimated 915 lives between the years 2007 and 2013. This represents a 15 percent reduction in drunk-driving related deaths compared to states without legislation requiring the ignition locks for DUI offenders, say the researchers.
Dr. Elinore J. Kaufman, lead author of the current study, and Dr. Douglas J. Wiebe, senior author, say accidents involving alcohol lead to 11,000 deaths each year and make up nearly 30 percent of all vehicular fatalities. Their research shows making ignition interlock devices mandatory for repeat DUI offenders would go a long way toward bringing down the numbers of these deaths.
One of the biggest supporters of mandatory ignition interlock devices is Mothers Against Drunk Driving (MADD), an organization founded in 1980 by a mom whose daughter was killed by a drunk driver. According to MADD, the average drunk driver has driven drunk 80 times before a first arrest. MADD also reports that, on any given day, more than two million drunk drivers who have had three or more prior convictions are on the road… with you!
The need to require convicted drunk drivers to prove they are sober before starting a car is evident to mothers and lawmakers in the 22 states where ignition interlock regulations apply to all drunk driving offenders. (All states mandate some use of these devices, with most states requiring them only under certain circumstances, such as a very high level of inebriation at first offense.) MADD estimates these laws have prevented 1.77 million attempts by a driver to drive with an illegal blood alcohol concentration (BAC) of .08 or higher.
To understand whether laws requiring DUI offenders deploy the ignition device have helped, the research duo requested data from the National Highway Traffic Safety Administration. Then, they examined the number of alcohol-related crash deaths in 18 states requiring ignition locks for everyone convicted of a DUI (as of 2013, the most recent statistical year) and compared this to the number of alcohol-related crash deaths in states without mandatory interlocks for all offenders.
Their analysis finds these laws are effective. States with mandatory locked-ignition laws reported the number of lives saved totaled 1 person for every 125,000 each year. This compares to 1 person saved for every 110,000 after airbags became a mandatory safety feature in cars; and 1 person saved for every 500,000 after the drinking age was raised from 17 to 21 years old.
As of 2010, about 300,000 interlock devices were in use nationwide, up from 100,000 just four years before, but they are still only used in about 30 percent of drunk driving convictions, wrote the authors. With faster, more compact designs in development, the authors recommend wide adoption to prevent needless injuries and deaths.
