Fuel restrictions in Merseyside off-road bike clampdown
Petrol stations are being asked not to sell fuel to under-16s during a clampdown on use of quad or scrambler bikes in Merseyside.
Anti-social riders of the "potentially lethal" bikes cause "disruption and misery", particularly in summer, Operation Brookdale officers said.
The force said scrambler bikes were used as getaway vehicles for gunmen in 12 shootings it dealt with last year.
Police will speak in schools about the bikes' dangers and laws on their use.
A 16-year-old boy died after he hit a lamppost and came off a scrambler bike in Bromborough, Wirral, last August.
Ch Supt Mike Cloherty said: "In the wrong hands these bikes are potentially lethal and people need to understand the legislation in relation to the legal use of these bikes, and the potential consequences of driving these bikes irresponsibly."
The bikes can be seized if they are not insured and can only be driven on a road or in a public place if the rider has a driving licence, insurance, MOT and vehicle excise licence if required.
