DOA will air on television this weekend but viewers can watch the show on the BBC Three blog now.
The programme stars Karen Taylor and former My Family actor Kris Marshall as two paramedics working on the night shift.
Earlier this year, BBC Three previewed three comedies before they were broadcast on television. Pilots Stanley Park, Dappers and Pulse were also available to watch online.
DOA will air on BBC Three on Sunday at 9.30pm.
