The image of a car ploughing into the side of the pushchair that was carrying her two-year-old son will never leave Amy Robinson.
The moment of sheer horror and panic is one that returns to her mind every time she nears a road.
"I will never lose that image," said Amy, 29.
"The pushchair was hit and dragged along the road and then it tipped over. I was in sheer panic, wondering if Zak was alive or dead."
Mrs Robinson, who was 17 weeks pregnant at the time, also feared for the safety of her unborn child.
Disabled after falling out of a tree when she was 13, she was knocked out of her wheelchair, suffering a broken leg.
"I will never lose the image of seeing a car plunge into the side of the buggy. My natural reaction was to keep hold of the buggy," she said.
"Zak didn't make a sound at first as he had been asleep in the pushchair, so I was left waiting for a cry to know he was OK. I honestly thought he would be dead.
"I was clinging on to the pushchair all the time, and once I saw Zak was fine, my thoughts immediately turned to the fact I was pregnant and then the health of my baby.
"You can't see your unborn child, so you have no idea whether serious damage has been caused. It was a very worrying time."
Incredibly, the accident happened on what should have been the safety of a pedestrian crossing in Wednesday Market, Beverley, in December 2011.
Amy, who lives in the town, was with her husband and full-time carer, Craig, now 32, and their son, Josh, now 11, when a car drove straight into them.
The incident had a big impact on Amy, physically and mentally.
In the months after the accident, she had to cope with being pregnant, having two other children and having her leg fixed in a straight position in her wheelchair to allow it heal.
The trauma of the time is something she still feels even today.
"I ended up going to see a counsellor over it," she said.
"It was only the beginning of last year that I went to town without going in a car. It took me two years because I didn't want to cross a road."
Amy is sharing her story to mark National Road Victims Month, organised by RoadPeace.
The charity campaigns to raise awareness of safety issues on the country's roads, and remember those injured or killed.
The event is held in August each year as there is increased risk of children being injured or killed while on holiday from school and for those travelling on holiday being involved in a car crash.
What happened to Amy has made her far more aware of the dangers of the road, and she says she sees many instances of people failing to take enough care when crossing.
"You see people run across the road with their kids," she said.
"I always have to try to use the crossings because I need the kerbs to be flat, so my incident shows that just because you are on a cross- ing, you are not necessarily safe. It wasn't like I had missed it and bolted across the road or anything.
"I'm very cautious now and I don't even use that crossing anymore. I go the long way around to avoid it."
Amy, who happily went on to give birth to Skye, now two, who was uninjured in the accident, said she continues to suffer problems with her leg.
It does not bend properly and she has had blood clots.
"For the first three or four months, I didn't leave the house," she said.
"My leg was fixed in a straight position. I'm already disabled and couldn't walk anyway, but I couldn't use my own wheelchair after it happened and I didn't feel safe in the chair I had to use instead."
Amy has recently received an undisclosed amount of compensation for her pain and suffering as a result of the accident.
Jane Woodcock, senior legal executive at Hull- founded Neil Hudgell Solicitors, said the accident had a long-lasting effect on Amy physically and psychologically.
"Given she had Zak in the buggy at the time and was pregnant with Skye, she went through all of the worry related to their health and safety at a time when she had suffered a nasty broken leg herself," she said.
"This accident left her in considerable pain and discomfort throughout her pregnancy, losing her skills and independence, and placing a great strain on her emotionally and physically.
"We are delighted to have brought this case to a successful conclusion for Amy and hope she and her lovely family have a happy and safe life."
