I understand why speed cameras are needed at all times in construction zones; even if there are no workers present, the highway lanes are often narrow and twisting and require a lower speed ("Delays, detours and dead ends on cameras," Nov. 25).
Regarding school zone cameras, however, are we supposed to believe that a child hit by a vehicle traveling 12 mph over the speed limit sustains more serious injuries than a child struck by car going only 11 mph over the limit?
Since the answer is obviously not, why then are vehicles ticketed only if they exceed the posted limit by 12 mph or more? The speed limit is the law, and anyone exceeding it is in violation.
This shows that speed cameras are and always have been simply a revenue source that our government needs to continue its excessive spending.
