What is the legal limit of blood alcohol concentration among adults aged above 18 for driving in India?

Appeared in: UPUMS Nsg officer-2023

Explanation

The legal limit for Blood Alcohol Concentration (BAC) for driving in India is 30 mg per 100 ml of blood, as stipulated by the Motor Vehicles Act, 1988.
This is equivalent to a BAC of 0.03%.
Even at levels between 20-30 mg/dL, alcohol begins to cause a decline in cognitive ability and slows motor performance, which justifies this strict limit for safety.
Exceeding this limit while driving is a criminal offense and can lead to penalties including fines, imprisonment, and license suspension.

Why Other Options Were Wrong

Option A: This value is more than double the legal limit in India. It is closer to the legal limit in countries like the USA (80 mg/dL).
Option C: This value is significantly above the legal limit of 30 mg/100 ml in India.
Option D: While this is a very low and safe BAC level, it is not the defined maximum legal threshold.
