Red light cameras are ALWAYS money grab rackets, not safety programs.  The cameras are very expensive, typically $4,000 to $5,000 per camera per month.  They MUST issue most tickets to safe drivers who endangered no one, or the total fines won't be enough to even cover their costs.  Two scams are used.  1) Yellow intervals are set slightly to short for the ACTUAL perception/reaction time and ACTUAL approach speeds of at least 85% of the drivers (safest timing method).  Adding one second to the yellows will almost always reduce violations by about 80%.  2) Cameras ticket safe slow rolling right on red turns or drivers who stop just over the line, actions that almost never cause crashes.  Only six one-hundredths of one percent (0.06% or 0.0006) of injury crashes involve a right on red turn - with or without a full stop.  Red light cameras are a money grab racket NO ONE should support.  James C. Walker, National Motorists Association
