Police in South Gloucestershire have received reports of parents hiring electric scooters for their children.
Staple Hill Councillor Ian Boulton revealed officers have asked him to warn locals it is not legal to ride a Voi scooter without a valid driving licence.
He posted in the Staple Hill and Mangotsfield Residents Facebook group: "Our beat team have received anecdotal reports that parents have hired Voi scooters for their children. You must be 18+ and have a valid driving licence to hire a Voi scooter.
"Permitting another to drive any vehicle, including an e-scooter, otherwise in accordance with a licence is an offence and South Gloucestershire Neighbourhood Policing have asked me to remind members of this group that anyone found enabling someone to use an e-scooter not in accordance with the law and terms of hire will be liable to a fine.
"Our beat team will be prioritising enforcement of illegal e-scooter use to try and avoid a child being killed or injured."
Voi e-scooters can be rented through the West of England Combined Authority's trial scheme. Using privately owned e-scooters in public space is illegal.

Avon and Somerset police tweeted on Saturday April 17 that an e-scooter user had been arrested in South Gloucestershire after riding at nearly twice the legal alcohol limit.
"While the electric hire scooters maybe legal to ride, they aren’t if you’re over the drink drive limit," the force posted.
Pensioners, visually impaired people and parents with buggies have complained the trial is creating problems with how the scooters are left in streets. Voi tells users to leave them in designated “parking zones”, but these are often just wide pavements or bus stops.
There has also been praise for the scheme. Earlier this week, transport chiefs said the trial had "to be seen as a success", pointing out the region is "rapidly heading towards a million kilometres of scooter ride distance" since launching last October.
