Enough children to fill a classroom have died due to speeding in northern Ireland since 2000.
Dozens of young people lost their lives in what should be a "wake up call" for drivers, it was revealed.
Assistant Chief Constable Stephen Martin said: "The real tragedy is most, if not all fatalities, could have been prevented."
Research shows that speeding drivers thought they were in control - but environment minister Mark Durkan said the consequences were uncontrollable.
Mr Durkan said: "Speeding is shockingly shameful. People are losing their lives long before they have the chance to fulfil their potential. "Families are being destroyed forever." he said those most at risk of causing speed-related deaths and serious injuries were 17-to-24 year old men, followed by men aged 25- to 34.
Since 2000, 28 children have lost their lives due to speeding.
