A lollipop man says he is fed up of putting his "life on the line" after falling victim to a second hit-and-run in four months.
David Ellis, 41, has warned children's lives are also being put at risk as drivers refuse to stop when asked outside Monks Abbey Primary School in Lincoln.
Mr Ellis said he was left "shaken" when a female driver struck him from behind while he attempted to escort a group of pupils across Milman Road safely.
The Echo reported in May how a similar incident caused Mr Ellis to suffer a broken hand. The driver in that incident was never traced.
"It is beginning to feel like I am putting my life on the line every time I step out onto the street," said Mr Ellis, who lives in Lincoln.
"When you are getting hit by cars you can't help but wonder whether it's worth the trouble.
"There was static traffic as cars waited to get onto Monks Road. That is when I walked between two cars to help the children across.
"As they crossed the road, a couple of cars in front of me pulled forward. I had my back to the car behind me and the next thing I was being hit in the back of the leg and the car drove on.
"The driver, a woman, shouted sorry but just carried on – without asking how I was.
"The problem I most worry about is the one of children's safety.
"This happened during the morning run and I recorded the incident with the police.
"During the afternoon run there were nine different drivers that didn't stop when I stepped out into the road. What chance do these children have? Something needs to be done. It is very worrying and it is just a matter of time before something really serious could happen."
Sue Blyth, assistant head teacher at Monks Abbey School, said: "We are really concerned about what is happening outside our school. The whole traffic situation on Monks Road is terrible. Even when teachers go out to grab a sandwich at lunch, they feel they are taking their life in their hands.
We don't want children to be at risk and this is a huge concern. Motorists just drive far too fast."
The school has 425 pupils.
Meanwhile, Lincolnshire Police is appealing for witnesses.
Anyone who saw the incident is urged to call the non-emergency number, 101.
Police spokesman James Newall said they were looking for the driver of a silver Citroen Saxo in connection with the incident.
He added: "Drivers need to stop when they are asked because lollipop people play a very important role in taking children across busy roads."
