The government is urging everybody, including key workers, to avoid public transport. The advice comes amid new guidance from the government on how it plans to ease lockdown restrictions in the UK.
In England, employers are being urged to open up workplaces if their employees cannot work from home - but people should avoid travelling to and from work on public transport "where possible".
The government has acknowledged that the number of people needing to use public transport will increase as more people return to work - and the new guidance says the government is aiming to "bring services back towards pre-Covid-19 levels as quickly as possible".
