Autowatch Breathalok

Driving under the influence of alcohol is one of the biggest threats to road users all over the world, and for businesses with road transportation at the heart of their operations, compliance with local regulations regarding drunk driving is a responsibility that simply cannot be ignored. 

Since their first introduction to the market in 2003, Autowatch Breathalok products have been at the cutting edge of tethered and wireless alcohol ignition breathalyzer systems to help keep your vehicles, your staff members, and other road users safe. In the years since then, the car breathalyzer ignition (formally Interlock) systems have become an indispensable tool in the prevention of intoxication whilst driving. These systems are vital against ‘drink driving’ in both commercial and correctional contexts around the globe. From North America and Europe to South Africa and the United Kingdom, you will find Autowatch Breathalok products in any setting where adherence to an alcohol-free policy is required. 

Manufactured to the highest standard of quality, Autowatch Breathalok products meet all relevant industry benchmarks and certifications.
