Effects On Operating A Vehicle

After alcohol consumption, many skills required for safe driving like reaction time, visual acuity, coordination, comprehension, concentration and judgement becomes impaired.


The first thing which gets affected by drinking is mental faculties. The level of alcohol of minimum 0.2% (under the state’s legal limit) can reduce the reasoning capacity, making it very difficult to respond or plan ahead appropriately to immediate surroundings.


Individuals consuming alcohol in small amounts experiences notable decline to focus at hand on their task. Many traffic accidents that are alcohol-related are caused due to intoxicated driver having a short span of attention. The drivers who are drunk get distracted very soon and when they stop their focus, crashes occur very often.


Drivers should interpret and receive sensory information. It is an unbendable skill to have an ability of making reasonable assessments on road at immediate notice. A research has proved that at the time a driver is drunk, the sensory inputs to which are they can respond and interpret correctly, gets decreased.


Alcohol attacks the ability to control the eye movements and see clearly. Studies have proved that a drunken person focuses on often a central and single point for long duration of time and therefore the drunk drivers are less aware of important surrounding zones.

Motor control and visual acuity of eyes get decreased due to the absorption of alcohol in the bloodstreams. At a slow rate, such skills get affected, however many researchers does not believe the significance of their impact is enough for the traffic accidents which are alcohol-related.

Reaction Time

It is shown by the studies that a driver intoxicated under alcohol’s influence is unable to give response to the stimuli as soon as it occurs. In a normal situation, a driver can respond with sufficient time in reducing the risk of serious damage to sudden breaking of a car or a small child running or crossing the street.

It takes much time for the brain of a drunken driver to process the entire data that has been received. The time span of attention gets shortened, the vision gets blurred, judgment ability gets skewed and the ability of interpreting the information also gets diminished. All these skills and abilities are required for a driver driving any motor vehicle. When the drivers are drunk by alcohol consumption, they should refrain themselves from driving the vehicle.
