The accident happened on the A18 at Mortal Ash Hill, near Scunthorpe, just after 0800 BST on Friday.
Humberside Fire and Rescue Service said nine coach passengers had serious injuries and firefighters had to free three people from the wreckage.
The injured people were adults on a day trip to London. The A18 was closed for several hours after the crash.
Four crews of firefighters from Scunthorpe and Winterton stations were called to the scene.
A fire brigade spokesman said the injured passengers were taken to local hospitals in a fleet of ambulances.
He said paramedics used minibuses at the scene as triage points.
A Humberside Police spokeswoman said the Hornsby Travel coach collided with the rear of a large skip lorry between the Morrisons supermarket and the Corus steelworks.
"There were initially some passengers trapped, but that was due to damage to the bus door, rather than them being trapped in their seats," she said.
All the passengers and the driver, who was experiencing pain in his sternum, were taken to hospital for checks and later released.
Most suffered from minor injuries including shock, cuts and bruises.
A spokesman for Hornsby Travel said a representative for the company had visited Scunthorpe General Hospital, where the injured passengers were treated.
The firm organised mini buses and taxis to take the passengers home as soon as they were released from hospital.
The coach was on its way to Lincoln to pick up passengers for a day trip to London.
Those passengers were contacted and informed the trip had been postponed.
The cause of the accident is under investigation.
