All drinking alcohol, taking cold medication and suffering from the flu affect your abilities to drive, focus and react on time. In the case of alcohol this occurs because the alcohol reduces your ability to drive and coordinate movements, also it makes your vision dull which are factors that can lead to accidents. On the other hand, flu produces symptoms such as fever, tiredness and swollen eyes that affect the driver's level of attention and time to react which means the driver is more likely to have an accident. Finally, the cold medication produces drowsiness that along with flu symptoms increases the likelihood of accidents. Thus, never drive in any of the situations previously described.
