What the Law Says
Section 185 MV Act: No person shall drive or attempt to drive a motor vehicle in any public place while the concentration of alcohol exceeds 30 mg per 100 ml of blood (tested by breathalyser) or 150 mg per 100 ml in urine. Penalty: first offence — imprisonment up to 6 months and/or fine ₹10,000; subsequent offence (within 3 years) — imprisonment up to 2 years and/or ₹15,000. The 2019 amendment added that causing death while drunk driving can attract culpable homicide charges under Sec. 304A IPC/BNS.
💡 Why This Rule Exists
Alcohol impairs reaction time, vision, coordination, and judgement — all essential for driving. At India's 30 mg/100 ml limit (0.03% BAC), impairment is already measurable. Countries with 0.05% or 0.08% limits see higher drunk driving deaths. India's strict limit reflects the high-density, unpredictable nature of Indian traffic where faster reactions are essential.
Key Facts
- 1
30 mg/100 ml = approximately 1 standard drink for an average adult (varies by body weight).
- 2
You can still be charged even if under the limit if your driving was impaired.
- 3
Refusing a breathalyser test: treated as an admission of guilt under CMVR Rule 20.
- 4
Drugs (cannabis, prescription drugs affecting driving): covered under Sec. 185 — same penalties as alcohol.
- 5
Commercial vehicle drivers: even stricter enforcement — any positive BAC reading can mean disqualification.
- 6
Drunk driving is the third-leading cause of road accident deaths in India (MoRTH).
⚠️ Common Violations
- ›
Driving after "just one or two drinks" — BAC can exceed 30 mg even after a single large drink for small-framed people.
- ›
Driving the morning after heavy drinking (residual BAC above limit for 8–12 hours).
- ›
Drug-impaired driving (cannabis, opioids, sedating antihistamines) — under-prosecuted but equally dangerous.
