Toyota has announced it is developing a breathalyser that will lock the ignition of a vehicle to keep people with high levels of alcohol off the road.
Drivers blow into the device, which analyses their breath without them having to put the product in their mouths.
If the breath-test result is positive, the system either warns the driver or locks the vehicle’s ignition, depending on the level of alcohol detected.
The hand-held breathalyser includes a digital camera that photographs the driver’s face to prevent a false reading from someone other than the driver.
Toyota is testing the device with its wholly owned subsidiary Hino Motors, one of the world’s leading truck manufacturers.
