The IoM government is being asked to clarify rules around mandatory mask wearing on public transport.
MHK, Jason Moorhouse is to ask a series of question in Tynwald this week.
He wants to know how bus drivers can enforce the new rule which was brought in on 30th November to limit the spread of COVID-19.
Mr Moorhouse will also ask if masks and sanitiser are provided onboard.
Meanwhile, a taxi driver who says the trade has been "hung out to dry" by the government is also asking for more clarity.
Barry Murphy says there needs to be more official guidance about exemptions and how drivers should deal with customers who refuse to mask-up.
