As per the Transport Secretary's announcement, wearing face coverings on public transport will be mandatory in England from Monday 15th June.
The new guidance refers to face coverings - not surgical masks - which can be made from home.
Exemptions will be made for very young children, the disabled and those with breathing difficulties.
You can be refused travel if you don't comply and could be fined. Alongside transport operators, this will be enforced by the British Transport Police, as necessary.
