Republic Act No. 10586, formally known as the "Anti-Drunk and Drugged Driving Act of 2013," is a landmark piece of legislation in the Philippines aimed at ensuring road safety by penalizing individuals who operate motor vehicles while under the influence of alcohol, dangerous drugs, and other similar substances.
Under Philippine law, driving is considered a privilege, not a right. RA 10586 provides the legal framework for law enforcement to conduct tests and impose severe penalties on violators to mitigate road accidents caused by impaired judgment.
I. Mandatory Screening and Testing Procedures
The law empowers Law Enforcement Officers (LEOs) and deputized agents from the Land Transportation Office (LTO) to conduct two primary forms of testing if they have "reasonable ground" to believe a driver is under the influence.
1. Field Sobriety Tests
Before using technical equipment, the officer may require the driver to perform three standardized tests:
- The Eye Test (Horizontal Gaze Nystagmus): The driver must follow a moving object (like a pen or flashlight) with their eyes to check for involuntary jerking.
- The Walk-and-Turn Test: The driver is required to walk nine steps, heel-to-toe, along a straight line, turn on one foot, and return.
- The One-Leg Stand Test: The driver must stand on one foot and count aloud for about 30 seconds.
2. The Breath Analyzer Test (Alcohol)
If the driver fails the field sobriety tests, the officer will utilize a Breath Analyzer (Alcohol Breathalyzer) to determine the driver's Blood Alcohol Concentration (BAC) level.
3. Drug Testing
If there is reasonable ground to believe the driver is under the influence of dangerous drugs, the officer shall bring the driver to the nearest police station to undergo a drug screening test and, if necessary, a confirmatory test.
II. Blood Alcohol Concentration (BAC) Thresholds
The law distinguishes between private motorists and professional drivers/operators of heavy vehicles.
| Category of Driver | BAC Limit |
|---|---|
| Private Motor Vehicle Drivers | 0.05% or higher |
| Public Utility Vehicles (PUVs) | More than 0.00% |
| Trucks and Buses | More than 0.00% |
| Motorcycles | More than 0.00% |
III. Penalties and Sanctions
The penalties under RA 10586 are graduated based on the severity of the incident (i.e., whether the DUI resulted in physical injury or death).
1. Criminal Penalties (Fines and Imprisonment)
If the violation did not result in physical injuries or homicide:
- Imprisonment: Three (3) months.
- Fine: Php 20,000.00 to Php 80,000.00.
If the violation resulted in physical injuries:
- Imprisonment: The penalty provided in Article 263 of the Revised Penal Code (RPC).
- Fine: Php 100,000.00 to Php 200,000.00.
If the violation resulted in homicide:
- Imprisonment: The penalty provided in Article 249 of the RPC.
- Fine: Php 300,000.00 to Php 500,000.00.
2. Administrative Sanctions (Driver's License)
Beyond the criminal fines and jail time, the LTO imposes strict administrative actions against the driver's license:
- For Non-Professional Drivers:
- First Conviction: Confiscation and suspension of license for twelve (12) months.
- Second Conviction: Permanent revocation of the driver's license.
- For Professional Drivers:
- First Conviction: Permanent revocation of the driver's license. Revocation means the individual is perpetually disqualified from driving a motor vehicle in the Philippines.
IV. Refusal to Undergo Testing
It is a common misconception that a driver can avoid a DUI charge by refusing the field sobriety or breathalyzer tests. Under Section 8 of RA 10586, if a driver refuses to undergo the required tests:
- The LEO shall confiscate the driver's license immediately.
- The driver's license shall be automatically revoked.
- The LEO shall proceed with an arrest based on other physical manifestations of intoxication observed.
V. Probable Cause for Traffic Stops
An officer cannot stop a vehicle at random for DUI testing without probable cause. Probable cause includes:
- Moving violations (lane straddling, swerving, sudden stops).
- Equipment violations (broken lights, plate violations).
- Involvement in a traffic accident.
- Observation of "physical manifestations" such as the smell of alcohol, slurred speech, or bloodshot eyes.
