Most frequent are reports about how a state vehicle is being driven. Calls tell us about state vehicles exceeding the speed limit, failing to signal lane changes, following too close, failing to yield right-of-way or other driving behavior that could lead to a crash.
Poor driving habits are precludes to crashes. Little thing we don't notice anymore about our driving turn deadly in the wrong circumstances. Most people report they are "good" drivers; it's everyone else out there. Those poor habits are noticed by others when it's an E-plate speeding, following too close or failing to signal.
Citations including photo-radar tickets are reported through various channels. The state DOES NOT PAY for parking fines or traffic tickets. The cost is the driver's personal expense. Fines may not by requested as part of reimbursement. Moving violations are investigated in the same fashion as a citizen report.
