199. Dispositivo de bloqueo por alcohol
Un dispositivo de bloqueo por alcohol, también llamado alcolock, es un equipo de análisis de aliento conectado al sistema de arranque del vehículo. Antes de poder arrancar, el conductor debe proporcionar una muestra de aliento por debajo de un límite de alcohol programado. El dispositivo también puede exigir pruebas adicionales durante el viaje y registrar información sobre pruebas, intentos fallidos y posibles manipulaciones. En algunos países se utiliza como medida de seguridad o requisito legal para conductores condenados por infracciones relacionadas con el alcohol.
What is an ignition interlock device?
An ignition interlock device is a breath-testing system connected to a vehicle that prevents the engine from starting when the driver’s alcohol concentration exceeds the programmed limit.
How does an ignition interlock work?
Before starting the vehicle, the driver provides a breath sample. If the alcohol concentration is below the permitted threshold, the vehicle can be started.
Can an ignition interlock require another test while driving?
Some systems require additional breath tests during a journey to confirm that the authorised driver remains compliant. The exact procedure depends on the device and applicable rules.
Does an ignition interlock record information?
Yes. Many systems can record breath-test results, failed attempts, events and possible attempts to interfere with the device.
Who may be required to use an ignition interlock?
Depending on the country, an ignition interlock may be required for drivers convicted of serious or repeated alcohol-related driving offences.
Can another person blow into an ignition interlock for the driver?
No. Having another person provide the breath sample defeats the purpose of the system and may be treated as tampering or non-compliance under the applicable rules.
