Driving under the influence of alcohol and drugs increases the chances of a crash, resulting in either serious injuries or deaths. For instance, the chance of getting crashed for a driver with BAC (Blood Alcohol Level) of ≥ 0.04 g/dl gets increased significantly. Hence, it is ideal for every vehicle driver to refrain from drinking and using drugs before stepping on the road, as these substances impair judgment and disturb the reflex time.

According to WHO, the safe limit of BAC (Blood Alcohol Level) for the general population is ≤0.05 g/dl. However, a limitation of ≤ 0.02 g/dl is set for young and novice drivers. Therefore, setting up sobriety checkpoints and random breathing tests is necessary to prevent people from drinking under the influence.
