Owners of miniature motorcycles have been told by police they are no longer taking a lenient approach to those who are caught breaking the law.
Police now have the power to seize and destroy mini bikes
The warning from Thanet Police followed the prosecution of a 20-year-old man from Broadstairs fined nearly £200.
In another incident, a 19-year-old man from Margate suffered serious injuries after his machine collided with a car.
Pc Dave Towner said the bikes were no longer new to the market and owners had had plenty of time to learn the rules.
He said the illegal use of the bikes on roads and in public places was an ongoing problem in Thanet.
The only place that mini bikes can be used lawfully is on private land.
Thomas Waeling, of St Peters Road, Broadstairs, was prosecuted after admitting riding his black mini bike at night time in Broadstairs Road on 9 July with no lights, reflectors, or tread pattern on his tyres.
He also admitted having no insurance, motorcycle helmet or licence.
Seize and destroy
Magistrates fined him £193 and added six points to his car driving licence.
If owners of the bikes want to ride them on the road they have to have a road tax disc and insurance for the machines, and ensure they have lights, reflectors, treaded tyres and a horn.
The rider must wear a helmet and hold a valid licence.
Under new powers that came into force last month, police officers now have the power to seize the bikes, and destroy them.
