intake while driving increases the rate of road crash and outcome of injury and
death. The risk increases exponentially as more the alcohol intake. People with
BAC (blood alcohol concentration) of 0.02 g/dl and 0.05 g/dl have a minimum of
three times greater risk of fatality in road crash. A BAC of 0.05 g/dl and 0.08
g/dl have at least six times greater risk of fatality in road crash and will
rise exponentially for a BAC above 0.08 g/dl. Drinking has also been associated
with high risk road behaviours such as speeding and not wearing safety belts.
Young and novice driver have more risk than experience and older driver when
under the influence of alcohol (Global status report on road safety 2015, 2015). Alcohol is the
drug associated most frequently with all
kind of motor vehicle crashs, moreover motorcycle drivers are more likely to
have consumed alcohol than are other motor-vehicle drivers in fatal or non
fatal crashes (NHTSA, 2007).
