The Road Safety Authority has said there were almost three times as many children killed on Irish roads in 2014, compared to the previous year.
Fourteen children aged 14 and under were killed last year, compared with five in 2013.
The figures were highlighted at an international conference on children and road safety taking place in Dublin today.
The RSA-hosted conference hopes to highlight the risks for children on roads through education, safety programmes and initiatives.
Consultant Paediatrician at Temple Street Hospital Professor Alf Nicholson said even though last year was a bad year for road safety in Ireland, the country is doing much better than before, but could still do better.
Speaking on RTÉ’s Morning Ireland, he said research showed children are more likely to be hit by a vehicle in summertime and on Friday evenings.
Prof Nicholson said: "Young people can do unpredictable things and we have to anticipate that. It's how fast you are travelling as a driver dictates the level of injuries for a child and whether they will survive or not."
He also appealed to people to use proper restraints for children in cars as lap belt injuries are one for concern. He said this is something they will be highlighting at the conference.
"It is ensuring that a child up to the age of 12 is appropriately restrained with a shoulder and a lap belt and comfortable in the back seat of the car.
"I think that's the most important thing. We have greatly improved our compliance in this area but it is still not perfect."
