More than 10,000 ambulances a week are caught in queues of at least an hour outside accident-and-emergency units in England, a BBC News analysis shows.
The total - the highest since records began, in 2010 - means one in eight crews faced delays on this scale by mid-November.
Paramedics warned the problems were causing patients severe harm.
One family told BBC News an 85-year-old woman with a broken hip had waited 40 hours before a hospital admission.
She waited an "agonising" 14 hours for the ambulance to arrive and then 26 in the ambulance outside hospital.
When finally admitted, to the Royal Cornwall Hospital, which has apologised for her care, she had surgery.
