Q724: Can I listen to music on a mobile device whilst driving a car or riding a bicycle?
It is not an offence in itself to listen to music on a mobile device whilst driving or cycling.
However, listening to music can be distracting, especially if it is not be possible for the individual to be fully aware of their surroundings. You need to be able to bring to bear all the senses you can whilst driving, and being able to hear is important in enabling you to be in proper control of your vehicle in traffic. Obviously, some people have the disadvantage that they cannot hear too well (or not at all), but the rest of us should not deliberately mask our senses and put ourselves at the same disadvantage.
A person using a device playing loud music, may, therefore, be deemed not to have proper control of their vehicle or to be driving without reasonable consideration for others, both of which are relatively serious offences.
