Paul Whittle of Whittle Car Services spoke after four vehicles were involved in an accident on Moy Street that resulted in four people being taken to hospital by ambulance.
Mr. Whittle, who works as a mechanic, said he had to contact three regular customers and let them know that their cars were scrapped.
The New York State Ambulance Service said it received a 4:47 p.m. 999 call on Friday, Feb. 18, and four ambulance crews were dispatched.
A NIAS spokesperson said: “After examination and initial treatment at the scene, four patients were taken by ambulance to Craigavon District Hospital.”
A PSNI spokesman said: “Police received a report of a four-vehicle accident in the My Road area of Portadown shortly after 4:40 pm on Friday, Feb. 18.
“Officers were present, along with colleagues from the Northern Ireland Ambulance Service, and three people were taken to hospital for treatment of injuries that are not considered life-threatening at this stage.”
Mr Whittle said the car rounded a corner and drove into a traffic sign indicating a turn and then crashed into three cars parked in the parking lot. He just parked one of the cars 10 minutes before the accident.
“This is the second accident at this turn in the last four months, and no one wants to know about it.
“A woman was injured, she was lying in the middle of the road when the ambulance arrived,” he said.
Mr. Whittle believes that the anti-skid surface on the road has not been changed since it was replaced nine years ago.
Mr Whittle says the road has been hit by accidents regularly – more than 40 in his lifetime – and calls for action.
