Launched in October at the 2011 Bus and Coach Show, and costing just £5 per week to install, run and maintain, Drivealyser can be fitted to almost any moving vehicle.

Drink driving harms companies, destroys reputations and ruins careers. Yet every year headlines are made by professional drivers who have caused crashes, injury and death by driving under the influence of alcohol. Drivealyser helps make sure this won’t happen.

The Drivealyser is a combined breathalyser and immobiliser that prevents a vehicle starting if the driver has more than a pre-set level of alcohol in their system, normally a quarter of the UK drink driving limit.

Even low levels of alcohol can impair judgement leading to scrapes and dents. Fitting Drivealyser across a fleet ensures drivers are effectively free of alcohol, reducing minor damage and insurance claims.

Fraudsters won’t be able to fool the Drivealyser. Re-tests are required at random intervals to prevent the system being tricked by a "friend" providing a single surrogate breath sample at the start of the day.

Drivealyser does more than prevent alcohol related incidents; it can provide the edge over competitors when tendering for new business by showing a stand out commitment to safety.

Fitting an interlock device may even become a prerequisite to winning work – it is already mandatory for French coach operators who carry children to have an interlock device fitted, and an interlock is demanded by Swedish local authorities before work is awarded.

Businesses stay in control but are completely supported with Drivealyser. From software to manage downloaded data and issue override codes, to adjusting the pre-set alcohol limit and re-test frequency. Drivealyser flexes to the needs of different businesses and fleet operations.

A serious drawback with some interlock devices is that they require expensive visits by technicians when calibration is needed. With the Drivealyser, business continuity is assured due to the exchangeable breathalyser handset – the base unit which controls the ignition and stores data is fixed. When calibration is required a replacement handset is sent out ahead of time and exchanged simplistically.

Fleets which install Drivealyser can see a step change in the way drivers approach their duties. Proving your fitness to drive is a different mindset to hoping you won’t get caught. Abstinence prior to work can bring about reduced absenteeism, improved productivity and better customer service.
