A new study finds people who drive home the morning after a night of drinking alcohol pose just as much of a threat as someone driving while intoxicated.

Researchers from Utrecht University and the University of New England put participants through several driving simulations after drinking an average of 10 alcoholic beverages the night before. They found drivers did not respond as quickly to environmental changes partially due to fatigue and poor sleep.

Drivers also made erratic lane changes and demonstrated poor reasoning skills while on the road.

Drivers had no alcohol in their bloodstreams at the time of testing. Currently, driving while hung-
over is not considered a punishable offense. A hangover is described as a short-term withdrawal from alcohol. Typical symptoms include intense dehydration and sleep deprivation.

Texas blood alcohol concentration limits for someone 21 and older is 0.08 percent. For commercial drivers, the states limit is 0.04 percent.
