Versatile and reliable alcohol interlocks

Today’s forward thinking automotive manufacturers look to ACS to provide solutions for safe and sober driving. Our solutions start right at your assembly line.


Together, we will develop completely integrated Alcohol Testing Solutions for the vehicles you produce. Installing factory fitted Alcohol Sensors that are capable of preventing an impaired driver from starting the vehicle helps ensure your customers enjoy a safer driving experience.

Quality solutions

Much like the cars our customers build, ACS takes the time to build it right the first time. We learn project requirements, conduct an extensive planning phase, propose designs, develop working prototypes, perform validation testing and then enter full production.

Wireless Devices

Whether your requirement is wireless communication between our alcohol interlock and the vehicle control system to authorize the starting of the vehicle, or transmitting breath test results wirelessly using Wi-Fi or third party telematics systems, ACS has a solution for you.

Vehicle integration

ACS has more than 10 years of experience in vehicle integration; including complex dedicated communications to the vehicles control system over CAN bus. Our experienced team of engineers and product managers can provide a custom solution at a value price.

Specialized tooling

ACS provides turnkey solutions for your alcohol interlock requirements. From simple customized holders for the handset to more complex implementations, our team can provide a complete solution including all essential tooling.
