The National Transport Authority's reminding people going to get a Covid 19 test not to take public transport.
It's echoing HSE advice to try to avoid others as much as possible, when going to their appointment.
They should use their own means of transport to get to the test centre, for example by car, bike or on-foot.
It says if people don't feel well enough to drive there, a family member or friend can drive them - if possible it's best to ask someone they live with.
Advice
They say you and your driver should follow advice on how to protect against the spread of the virus during your journey, and if you have a child who has an appointment to be tested, you can drive them.
People are reminded to follow the advice on respiratory hygiene, social distancing and wearing a face covering when in a test centre and travelling to and from it.
An NTA spokesperson said: “This advice was published by the HSE last year, but in light of the increase in testing activity, it is worth re-iterating at this stage.
“Public transport has had a very good record in safeguarding passengers and employees in Ireland throughout this crisis, and it is essential that we all continue to protect each other.”
