A new study out of the University of West England claims that a hungover driver is more of a danger on the road than someone driving drunk.
Chris Alford, Associate Professor at University of West England, says that participants drank heavily one night, and the next day, after sobering up, were asked to take basic driving tests.
"Things like their speed of reaction was slowed down, their variability in the way they drive was more erratic when they had a hangover," said Alford. "We also found that they're making errors things like crossing the central lines, the lane markings in the road. So you could say their driving was as if they were over the legal limit of alcohol but of course they didn't have that alcohol on board anymore."
A similar study in Holland showed the same results after testing drivers for an hour after giving them 10 drinks the day before.
"The magnitude of driving impairment is higher than that observed with a blood alcohol concentration of 0.05 per cent, which is the legal limit for driving in many countries," said Dr. Joris Verster at Utrecht University. "What's most often experienced is reduced concentration and alertness. Those are the things that are especially important for driving.”
