A series of serious crashes caused by drivers running red lights has prompted the New South Wales Government to install new cameras across Sydney.

At least nine new cameras will be installed by end of this year at intersections with a history of accidents.

For the first month of the new cameras’ operation, drivers will be given warning letters rather than fines for infringements.

The government’s Speed Camera Performance Review found red light speed cameras had reduced casualties by almost 40 percent, while pedestrian casualties were down by almost 45 percent.

The current penalty for running a red light is $433 and the loss of three demerit points.

All money raised from the cameras is put back into road safety programs, such as flashing lights in school zones and roadside barriers
