How does the Traffic Light System work?
What's the traffic light system?
On the 17th May at 4am, countries will be placed in a traffic light system:
Countries and territories will be assigned colours based on a range of Covid-19 health metrics, including vaccination numbers and infection rates.
The different traffic light colours communicate the risk of each country, along with any tests and quarantine required on arrival in the UK.
This list will be updated and reviewed every three weeks.
