That’s according to this article which suggests that driving for three hours at night can have the same effect as driving drunk. A study has found that as little as two hours continuous motorway driving in the dark can affect the drivers performance as severely as having a couple of drinks. Experts are now calling on the government to impose a maximum two hour limit on continuous night time driving in order to cut the number of accidents. I’m not entirely sure how easy it would be to enforce this if a limit were brought in but surely it is common sense that driving for several hours does make you tired. Particularly when driving on the motorway which is boring at the best of times.
