Gardaí have seized 41 electric mopeds and scooters during an operation in Dublin.
In a statement, they said the vehicles were seized for a number of offences under the revised Road Traffic and Roads Act.
These include the exceeding of maximum permitted design speed or power output as well as throttle-assisted e-mopeds that were unregistered and uninsured.
The 33 e-mopeds and eight e-scooters were recovered over a number of days this week across the Dublin area.
The garda statement added that that "while e-scooters and e-mopeds are now a common choice for commuters, it is important that those that are used are well regulated and safe.
"Always ensure that your choice of transport complies with the law, so all road users including yourself are safe," it added.
New regulations allowing the use of e-scooters in public places came into effect earlier this year.
The ordinary speed limit is set at 20km per hour and there are strict requirements around braking and lighting.
The regulations also prohibit the use of an e-scooter by more than one person at the same time, under 16s are banned from using them in public areas and they must not be fitted with a seat.
The vehicles must be safe and roadworthy and not "endanger, impede or inconvenience the driver, other road users or members of the public".
