It’s illegal to hold and use a phone, sat nav, tablet, or any device that can send or receive data, while driving or riding a motorcycle.
This means you must not use a device in your hand for any reason, whether online or offline.
For example, you must not text, make calls, take photos or videos, or browse the web.
The law still applies to you if you’re:
stopped at traffic lights
queuing in traffic
supervising a learner driver
driving a car that turns off the engine when you stop moving
holding and using a device that’s offline or in flight mode
