A SPEED camera installed temporarily at roadworks raised more than £1m in fines.
The camera on the M62 at Ferrybridge, West Yorkshire, caught 18,000 drivers speeding in an 18-month period.
It was installed in September 2003, when the speed limit was reduced from 70mph to 50mph while work was done on the motorway.
According to figures obtained under Freedom of Information, motorists caught by the camera were charged £1,088,000 in fines.
Temporary speed cameras have netted £7m in fines over the past two years, the figures showed.
