A bus carrying 70 schoolchildren mounted a kerb and hit a sign in rush hour.
The Stagecoach bus was taking children from Lancaster to Dallam School in Milnthorpe when the accident happened on Coastal Road near the traffic lights at Bolton-le-Sands.
The bus stop sign was bent over and there was also some damage to the front of the bus, following the accident on April 30.
A parent of one of the children on board the bus, who did not wish to be named, said: “The driver was going to the traffic lights at Bolton-le-Sands when he mounted the pavement and demolished a bus stop sign.
“They arrived at the school and there was a mark on the front of the bus. Some parents said their children were complaining of whiplash.
“There were lots of kids with bruising. The bus had 70 kids on it.
“If a schoolchild goes 100 yards on a bus by law they have to wear a seatbelt.
“But if they are going 15 miles on a double decker bus there is no such facility.
“I want Stagecoach to consider their responsibility .”
The incident occurred at 8.15am.Police saidthey were made aware of the incident after receiving a report from the school.
A spokesman said the bus was travelling to school when it was involved in a minor road traffic collision with a bus stop near Pasture Lane.
The bus had mounted a kerb and hit the bus stop.
Stagecoach said it was not able to comment.
Steve Holdup, headteacher at Dallam School, said: “We are very happy with the service that Stagecoach provides and the children are delivered on time and safely.
“We did not think this was any thing major as the students seemed to be perfectly happy when they got off the bus.”
