The Anti-Drunk and Drugged Driving Act, Republic Act No. 10586, penalizes driving a motor vehicle while under the influence of alcohol, dangerous drugs, or other similar substances. The law sets out an enforcement procedure. A law enforcement officer who has probable cause to believe that a person is driving under the influence, based on observed manifestations such as overspeeding, weaving, swerving, the smell of alcohol, bloodshot eyes, slurred speech, or the like, may flag down the vehicle and conduct field sobriety tests (standardized tests such as the eye test, the walk-and-turn, and the one-leg stand). If the driver fails the field sobriety tests, the officer shall administer a breath analyzer test (or, where applicable, a drug screening test). A driver found positive for the presence of alcohol beyond the allowed blood alcohol concentration, or for dangerous drugs, is arrested and charged. The allowed blood alcohol concentration is lower for drivers of trucks, buses, motorcycles, and public utility vehicles (for whom the law effectively requires zero or near-zero), reflecting their greater responsibility. A crucial provision concerns refusal: a driver who refuses to submit to the mandatory field sobriety and drug tests shall be penalized by the confiscation and automatic revocation of their driver's license, in addition to other penalties; refusal is not a way to escape consequences. The penalties for driving under the influence scale with the consequences: fines and imprisonment where no physical injury or homicide results, higher penalties where physical injuries result, and the highest where homicide results, with the corresponding penalties under the Revised Penal Code also applying, plus the perpetual revocation of the license in the gravest cases. Non-professional and professional license holders face different consequences. So RA 10586 punishes driving under the influence through a field-sobriety-then-breath-test procedure, imposes stricter limits on professional and public utility drivers, penalizes refusal to be tested with license revocation, and escalates penalties when injury or death results.
What Is Punished
RA 10586 penalizes driving a motor vehicle under the influence of alcohol, dangerous drugs, or similar substances.
The Enforcement Procedure
- An officer with probable cause (overspeeding, weaving, alcohol smell, slurred speech) may flag down the vehicle;
- Conduct field sobriety tests (eye test, walk-and-turn, one-leg stand); and
- On failure, administer a breath analyzer or drug screening test.
Stricter Limits and Refusal
The allowed blood alcohol concentration is lower (effectively zero) for drivers of trucks, buses, motorcycles, and public utility vehicles. Refusing the mandatory tests means confiscation and automatic revocation of the license — refusal is not an escape.
Escalating Penalties
Penalties scale with consequences: fines and imprisonment with no injury; higher where physical injuries result; and the highest where homicide results, with Revised Penal Code penalties also applying and perpetual license revocation in the gravest cases.
Practical Takeaways
- Field sobriety test, then breath test is the procedure;
- Refusing the test = automatic license revocation;
- Professional and PUV drivers face a near-zero limit.
Frequently Asked Questions
What is the procedure for a drunk driving check? An officer with probable cause based on observed manifestations may flag down the vehicle and conduct field sobriety tests. If the driver fails, the officer administers a breath analyzer or, where applicable, a drug screening test.
What happens if I refuse a sobriety or breath test? Refusal to submit to the mandatory tests is penalized by the confiscation and automatic revocation of the driver's license, in addition to other penalties. Refusing is not a way to avoid consequences.
Is the alcohol limit the same for all drivers? No. The allowed blood alcohol concentration is lower, effectively zero or near-zero, for drivers of trucks, buses, motorcycles, and public utility vehicles, given their greater responsibility.
How severe are the penalties? They scale with the consequences: fines and imprisonment where no injury results, higher penalties where physical injuries result, and the highest where homicide results, with the corresponding Revised Penal Code penalties and license revocation.
