Alcohol is a depressant. It depresses your central nervous system.

Your mental functions are affected and judgment is the first to go. This means that your ability to reason and caution are quickly reduced when you drink.

Remember, it doesn’t take much. Even small amounts of alcohol cloud your judgment.

Alcohol also impairs your ability to concentrate on the multiple tasks involved in driving. Multi-tasking behind the wheel include controlling vehicle speed, positioning your vehicle, knowing what is happening around you at all times, and maybe participating in conversation with passengers.

When drinking you are easily confused and not able to respond to emergency situations or to comprehend the meaning of simple signals.

Your ability to coordinate motor skills is also affected, and the loss of coordination severely affects your ability to react and reaction time. Reaction time is often slowed down by 25%. This affects your stopping distance, resulting in crashes and accidents which could have been avoided if you had no alcohol in your system.

The ability to see and hear clearly is severely impaired. Your peripheral vision goes away, resulting in tunnel vision. Your ability to depth perception is affected. It gets harder to judge distances and speed of other vehicles.

When you drive at night you will experience problems with on-coming headlights and blind driving. This is because alcohol slows down reactions of pupil.

Remember, among many other things, alcohol affects:

  • Judgment
  • Vision
  • Comprehension
  • Concentration
  • Reaction time
  • Coordination
