There is no safe limit for the amount of alcohol you can have before driving. There is also no way of knowing how long it will take for alcohol to be processed by your body.
Even a small amount of alcohol can affect your reaction times. Though there is a legal limit to how much alcohol can be in a person’s system before they can drive, it is impossible to say how many drinks or units it will take to reach it. It is also possible to still be over the legal limit the following day. An average liver can process approximately one unit of alcohol per hour, starting one hour after drinking has stopped. This means that if someone drinks 12 units, it can take them roughly 13 hours to fully sober up.
