Choosing a safe and sustainable car

Driver monitoring and reminders

Alcohol interlocks

Alcohol interlocks prevent drinking and driving. The driver must blow into a device on the key fob. If there’s alcohol on the breath, a computer in the fob won’t let the car be started. In some cases, the car can’t even be unlocked without a clear test.

Alcohol interlocks are not yet widely available in New Zealand, but are available in Europe, mainly as a feature for company fleet buyers.

Doze alert / drowsy warning

This detects when the driver is showing signs of tiredness, such as fixed staring or slow reactions – and alerts them that they may be fatigued. It can also be called a ‘driver fatigue countermeasure’. See ITS.

Intelligent seat belt reminders

These give an audible warning to fasten the seat belt, often rising in volume until the belt is in place.
