D.C. will lower its speed camera fines, Mayor Vince Gray and Chief of Police Cathy Lanier said Friday.

Fines for driving less tan 10 mph over the speed limit will drop by $25, from $75 to $50. Fines for going 11 to 15 mph over the speed limit will drop from $125 to $100.

But fines for going more than 25 mph over the speed limit will rise, from $250 to $300.

Critics of the proposal say the mayor is trying to preempt legislation from Ward 6 Councilman Tommy Wells that would slash fines more drastically -- to $50 for going up to 20 mph over the speed limit. The measure is set to be taken up by a D.C. Council committee next week.

D.C. collected $85 million in traffic camera tickets in 2012, The Washington Examiner first reported.
