The Queensland Police Service has apologised for interrupting a funeral procession to breathalyse drivers.
The family of 82-year old Vera Hohn say they were "appalled" when a hearse carrying their mother and another vehicle in the procession were pulled over by police for an RBT.
Son Jeffrey Hohn and wife Eve had travelled from Maryborough to Dalby for the funeral.
"We just were gobsmacked," recalled Eve.
"My mum's had no police reaction in 82 years of her life, and the day of her funeral she had problems with the police," Jeffrey said.
Police say when the officers realised the error, the drivers were waved back into traffic.
In a statement, Queensland Police apologised to the family.
"We acknowledge that this caused undue stress and respect the protocols of a funeral procession," the statement said.
