People are being urged not to buy e-scooters, scramblers, or quad bikes for children this Christmas.
As part of new laws introduced in May, people must be at least 16 years old to legally use an e-scooter.
They also banned from footpaths and users are not allowed to carry passengers.
In a statement, the Road Safety Authority said it wants to remind people that quad bikes and scramblers pose significant safety risks to children.
Four e-scooter riders were killed and 117 were seriously injured on Irish roads between 1 January 2020 and 31 December 2023.
During the same period, one other road user was killed and 20 more were seriously injured in collisions involving e-scooters.
Figures show that between 1 January 2020 and 31 December 2023, 49 people were seriously injured in collisions involving a quadbike or scrambler on a public road.
In the same period, there were three fatalities involving quad bikes or scramblers on public roads.
RSA Chief Executive Sam Waide said: "The greatest gift parents can give this year is ensuring the safety of their children.
"Parents should not consider purchasing a quad or an e-scooter for any child this Christmas.
"It is crucial for parents and members of the public to be recognise that quads and e-scooters are designed to be operated by those of an age to fully understand the dangers they pose when not being used appropriately and/or on uneven terrain."
