Drivealyzer Vehicle Interlock

The ONLY way to ensure ALL your
drivers are 100% Alcohol-Free
- EVERY time they drive!

The AlcoDigital Drivealyzer represents a real price-breakthrough for commercial interlock devices.  While not approved for judicial and offender programme use, the device is nevertheless a fully US DoT approved, commercial Breathalyzer-Immobilizer that offers the ultimate safety device at a price previously unheard of.

Random testing is one way of meeting your obligations under HSE legislation to ensure your employees are fit for duty, but inevitably it can only check a fraction of employees.  And in the case of workers who do not start from a single report centre, ONLY an immobilizer device such as the Drivealyzer will ensure absolute compliance, every trip, every day.

Using the same  UK-made DART Fuel Cell sensor found in Lion's UK Police Breathalyzers, Drivealyzer uses multiple Temperature, Humidity and Pressure sensors ensure accurate, consistent and fraudulent-free testing and rolling retests make absolutely sure it really WAS the driver who took the test.

Why so much cheaper?  Primarily because while the device still has anti-tamper logging built-in, it isn't tested and approved to the same levels as judicial interlocks used in offender programmes.  But in such instances, an individual has long-term, completely unsupervised opportunity to try and circumvent the interlock system. In commercial applications, this is very rarely the case; multiple drivers are often using the vehicles and/or they are regularly into works garages for maintenance and checking.  The Drivealyzer is just as difficult to circumvent as a normal vehicle alarm immobilizer, and as such easily exceeds the ability of 99% of employees. Power interrupts, bypass detections, violations etc are all logged in the data system to ensure reliable fraud-free operation.

Installation and Calibration. One of the most expensive issues with other Interlock Systems has always been the complex nature & expense of the installation and the need for either the vehicle to be driven to a specialist service centre, or for a representative to come out to the vehicle.  Both these issues have been resolved with the Drivealyzer. 

No more difficult to install than a standard vehicle immobilizer, most installations take less than an hour and can usually be done by in-house mechanics during normal service routines.

And to ensure zero vehicle down-time and minimal calibration costs, the handset is designed to be simply unplugged and replaced every six months with a replacement, calibrated handset.  Costs are dramatically reduced from up to £300/year of other interlocks to just £90 - and that includes a fully serviced replacement handset, every six months - you don't even have to buy the additional handset - it's provided as standard within the maintenance contract.

Increase Sales, Reduce Costs.....

Reduce Staff Costs - the Drivealyzer monitors every start, every day - with none of the staff and time costs associated with random testing programmes.

Generate extra Business by demonstrating your 100% commitment to driver safety, especially when bidding for PSV work involving the carriage of children and local authority business (in France it is now illegal to carry under-18's on a PSV without an interlock having been fitted!)

Improve Productivity - implementing an interlock programme often reduces absenteeism and sickness rates  as drivers reduce their alcohol intake prior to a work duty.
