Q: What should you do if your mobile phone rings while you're driving or riding?
Explanation
It's illegal to use a hand-held mobile or similar device when driving or riding, except in a genuine emergency. The safest option is to switch off your mobile phone before you set off, and use a message service. If you've forgotten to switch your phone off and it rings, you should leave it. When you've stopped in a safe place, you can see who called and return the call if necessary.
