Ford has developed new technology which can block incoming phone calls and text messages to help parents ensure their children drive more safely.

The new Ford MyKey 'Do Not Disturb' feature has been designed to help parents encourage younger drivers to concentrate on the road ahead by reducing phone-related distractions.

The feature works by blocking incoming phone calls or text messages from a Bluetooth-paired mobile phone, diverting calls to voicemail and saving text messages on the device for viewing later.

Ford MyKey also allows owners to programme a special key that can also restrict the vehicle’s top speed to 80mph and limit audio volume. In addition, MyKey encourages safety-belt usage, provides earlier low-fuel warnings and can be programmed to sound chimes at set points between 45 and 70mph.

MyKey will become available from next year on the Ford Fiesta before being expanded to other car models.
