MOTORISTS are being warned about the potential risks associated with using the new Apple Watch and other smartwatches while driving.

The Apple Watch will allow users to make and receive calls and check messages by operating the device on their wrists.

But the Institute of Advanced Motorists (IAM) says this could be a major cause of distraction that could significantly impair driving performance.

The IAM said constant alerts would require motorists' regular attention as opposed to using legal hands-free equipment.
