Motorists face a £15 hike in punishments for driving offences to fund a government scheme for compensating victims of crime.
The surcharge has been added to fines for those convicted of crime in court since 2007, with the cash going to finance support services.
But ministers now want to extend the levy to on-the-spot fines and fixed penalty notices.
This would include motorists caught speeding, using a mobile phone while driving, not wearing a seatbelt, or given a parking ticket. People found scrawling graffiti or being drunk and disorderly would also be hit.
Under the plans, the current fine of £60 for speeding would be increased to £75.
Campaigning group the TaxPayers' Alliance said the move amounted to a "stealth tax".
Spokesman Matthew Elliott said: "If the Treasury wants to raise money from the courts, it should be more honest and call this surcharge a 'justice tax'.
"By calling it a 'victims' surcharge' and applying it to minor motoring offences and parking tickets where there are clearly no victims, the Government is making a mockery of the tax system. This is clearly another stealth tax designed to plug Britain's huge debt."
