New Scientist (UK) – A new study shows that, despite all the talk of driving to work, many of us are actually less safe than we think.
The findings, published in the journal Transportation Research Part F, are based on the results of a survey conducted in New York and Washington DC.
They are based partly on the work of the researchers at Carnegie Mellon University, who were able to track driver behaviour at restaurants, bars and on buses across America in 2008.
They found that drivers were much more likely to drive on busy nights, and that they were significantly less likely to stop to check their mobile phone, rather than checking their car in for gas.
A survey conducted by Carnegie Mellon, the University of Washington and the Carnegie Mellon Transportation Research Institute found that in 2008, 20% of adults aged 16 and over in the US drove to work.
These figures have steadily increased over the last decade, with the number of people in the country driving to their jobs increasing from 3% in 1990 to 8% in 2008 to 13% in 2010.
Drivers who did not drive to work were more likely than those who did to report having drunk at least three alcoholic beverages within 24 hours of leaving the workplace, to use drugs in the previous 24 hours, to have had a blood alcohol level above .08 and to have committed a violent offence, according to the survey.
Those who did drive to the workplace had a significantly higher likelihood of being arrested for a violent crime, compared with drivers who did nothing to drink, and those who drank less.
However, the study also showed that while most of the drivers surveyed did not drink at the workplace and reported having had a drink or two, those who drove a lot and who reported driving a lot were significantly more likely.
Among drivers, those with a higher level of education were more than twice as likely to report drinking at work as those who had not graduated from college.
Drivers also had significantly higher levels of alcohol abuse symptoms, and had a higher risk of having a blood-alcohol level above 0.08 in their blood, compared to those who were not drinking.
They also had higher rates of driving while impaired, and a higher rate of driving drunk.
In Washington DC, a study by the National Institute of Drug Abuse found that 40% of drivers aged 20 to 29 were involved in driving offences, with drivers driving at least once a week, or more than three times a week.
The researchers also found that of the 2.7 million drivers in Washington DC who were surveyed, the vast majority were in the work force.
The National Institute for Occupational Safety and Health (NIOSH) also found the highest rates of drinking and driving among drivers.
Drivers were four times more likely in 2008 than in 2003 to have a blood concentration above the legal limit of 0.04 per cent.
The authors of the study said: “Our findings demonstrate the need for the public to understand the impact of alcohol and drug abuse on driver behaviour.
Alcohol and drug use is a serious public health concern.
The increased rates of drunk driving, impaired driving and drug-related incidents among drivers in the United States, combined with the increased risk for driving impaired and with other serious consequences for both drivers and passengers, are cause for concern.”
But the researchers warned that while drivers may not drink and drive, they are still much more dangerous than people think.
They said: Drivers who drive a lot are more likely, for example, to drink heavily.
Drivers that drink less may be drinking less, and may not have been drinking in the past.
“While there is no evidence that driving to a bar is necessarily safer than driving to the store, drivers who are more cautious are more at risk of being injured or killed,” said Dr Michael Siegel, who led the study.
Dr Siegel said that while drinking and drinking are dangerous, drivers may also be more concerned about other potential dangers. “
If you are worried about your health, you should avoid driving to your job and avoid driving on busy days.”
Dr Siegel said that while drinking and drinking are dangerous, drivers may also be more concerned about other potential dangers.
“Drivers should be cautious around the office, when you’re out with friends or in a meeting, because they are more vulnerable to alcohol and drugs,” he said.
“We also have to be cautious when we’re at home, because people with drug and alcohol issues are more prone to taking dangerous drugs and driving.”
The study, titled Drinking and driving in the workplace: drivers’ risk perceptions and perceptions of workplace safety, found that among the drivers, drivers with a college degree were much less likely than drivers with only a high school diploma to report driving to and from work regularly, to report being drunk in the last 24 hours and to report experiencing more drug- or alcohol-related offences.
Among those who reported being
