What is an ACS ALCOLOCK™?

The ACS ALCOLOCK™ is an alcohol ignition interlock that measures the breath alcohol concentration (BrAC) of the driver and prevents the vehicle from being started if the BrAC is over a predetermined limit. If a driver does NOT provide AND pass a mandatory breath test the vehicle is immobilized. It is important to note that the breath test is mandatory and unless a test is taken, the vehicle will remain immobilized.

Why use an ACS ALCOLOCK™?

The ACS ALCOLOCK™ (V3 unit in particular) is specifically designed to monitor, control and prevent drunk driving in commercial applications. In South Africa there is a severe drunk driving problem that is pervasive in all forms of transport, from passenger vehicles to heavy commercial trucks. The ACS ALCOLOCK™ serves as an effective and efficient solution to this serious problem.

How ACS ALCOLOCK™ works?



What information does the ACS ALCOLOCK™ collect?

  • start attempts (pass, caution and fail of breath test)
  • precise breath alcohol concentration (BrAC) readings for each start attempt and retest
  • retest information (pass, fail or missed)
  • any attempt to circumvent the ACS ALCOLOCK™ system
  • emergency overrides
  • calibration information
  • aborted tests
  • other non-alcohol related information
