A new report showed that drivers with heavy colds have slower reaction speeds than drivers who have drank four double whiskies.

According to an article in the U.K.'s Telegraph, experts claim that a person's driving ability drops by over 50 percent when they're suffering from the flu or a very bad cold.  In scientific testing, they've shown that reactions times dropped sharply and sudden braking became much more frequent, and the driver was less aware of surrounding traffic.

There are no official figures for accidents caused by sneezing or other symptoms of illness, but the insurance experts suspect that this number is pretty high as well.
