Motorists in north Wales have been hit with speed camera fines totalling £3.4m in the last financial year.
Richard Brunstrom runs a high-profile anti-speeding campaign
Most of the money will go to the police, with the rest going to magistrates courts, the Highways Authority and the Treasury.
Some of the cash will also be used to improve Prestatyn police station, where staff process the tickets.
The figures were revealed at a meeting of North Wales Police Authority at Colwyn Bay on Thursday.
Of the money taken in fines, £2.2m goes to North Wales Police, nearly £270,000 to magistrates' courts, and £396,000 to the highways authority.
A surplus of £496,000 goes to the Treasury.
The authority's director of finance Tom O'Donnell said: "Most fines go to the government, so I suppose all fines could be considered some sort of tax."
North Wales Police has run a high-profile - and sometimes controversial - anti-speeding campaign in its area, called Arrive Alive.
It has branded speeding motorists "anti-social" its attempt to reduce the number of deaths on the region's roads.
The force's chief constable, Richard Brunstrom, is head of road policing for the Association of Chief Police Officers.
The most recent criticism of his anti-speeding policy came last week in a BBC radio programme.
A former officer Phil Edwards, who is now a town councillor in Colwyn Bay, told Radio 4 that he thought the authority was too close to the police over its anti-speeding campaign.
In response, the authority said Mr Edwards was out of touch as most people in the force area supported Arrive Alive.
