Traffic enforcers told: Strictly follow drunk driving testing protocols
The agency stressed that breathalyzers cannot be used as an initial screening tool or as the sole basis for preliminary testing.
The Land Transportation Office (LTO) assured the public Thursday that deputized law enforcement officers will strictly follow standardized procedures when apprehending motorists suspected of driving under the influence of alcohol or drugs.
Under Memorandum No. MVL-2026-242, the agency instructed traffic enforcers to adhere to a mandatory sequence of sobriety testing before making an arrest.
Enforcers must first conduct a Field Sobriety Test. If a driver fails, an authorized breath analyzer may then be used to measure blood alcohol concentration.
The agency stressed that breathalyzers cannot be used as an initial screening tool or as the sole basis for preliminary testing.
“We want to ensure that no driver can drive while drunk or under the influence of drugs without being held accountable under the law,” LTO chief Assistant Secretary Markus Lacanilao said Thursday.
“But it is also important that apprehension procedures are properly followed because law enforcement must be strict, orderly, and free of lapses,” he added.
Beyond criminal penalties under Republic Act 10586, or the Anti-Drunk and Disabled Driving Act, the LTO highlighted its administrative authority under Section 27(a) of Republic Act 4136 to revoke the driver’s licenses of individuals who fail alcohol breath tests.
The Law Enforcement Service was directed to forward all apprehension records and instances where motorists refuse testing to the Intelligence and Investigation Division for formal review and administrative sanctions.
