Bus Eireann has updated its advice for customers using its Derry services.
The company has updated its guidelines under Level 3 of Ireland's Plan for Living with Covid-19 which came into effect countrywide from midnight last night.
Under Level 3 restrictions Bus Éireann and Expressway public services will operate at a capacity of 50%, as in Level 2.
However, all travel should be limited within your county, unless the travel is essential for the likes of work, education and other essential purposes.
Passengers are advised to only travel if it is absolutely necessary, to observe capacity signage on board vehicles and continue the mandatory wearing of face coverings on all services.
In a statement, Bus Éireann acknowledged their passengers in Derry for their high compliance rate with all Covid-19 restrictions on board our services to date and are asking their continued understanding and respect for all their frontline employees, including drivers and supervisors.
