In general, most road users are responsible when it comes to drinking and driving. After having a drink most people will not drive as the effects of those drink/s are well known. It is funny then to think that when it comes to not driving while tired is somewhat more ignored by road users. The end of the story is that driving tired can be just as dangerous and drinking under the influence.

A study done by the Sleep Foundation has found that being awake for 18 hours without sleep will affect a person’s ability to drive as much as having a blood-alcohol level of .05. Tired drivers will find they have difficulty concentrating and will have slower reaction times, additionally they run a higher risk of falling asleep at the wheel which would likely lead to an accident.
Aside from tiredness, they found that driving while using a phone has a similar effect of delaying reaction times while on the road. Nine out of 10 drivers admit to checking their phones while driving, even though this makes them 23 times more likely to be involved in a crash, reports Times Live.
“If compared to drunk driving, the Transport Research Laboratory in the UK says writing a text message slows reaction times by 35%, whereas the reaction time of a driver whose blood alcohol concentration is at the legal limit is slowed by 12%,” Eugene Herbert, MD of the MasterDrive driver-training company.

So, in conclusion, if you are tired and about to drive, treat it the same as you would if you have had a few drinks. Rather call a taxi, uber or get a lift from family or a friend. Additionally, especially on a long trip avoid sleep deprivation. Plan regular rest/sleep stops and avoid using your phone while on the road.
