How the breath test is performed

The tests to detect alcohol intoxication are performed by the officers and normally consist of checking the exhaled air with officially authorized breathalyzers, which determine quantitatively the driver’s degree of alcohol impregnation. The procedure must be carried out under conditions of strict hygiene, safety and control. Fuente: Reglamento de la Ley de Tránsito y Vialidad del Estado de Yucatán, Artículo 329.
