Photo Radar Proof Issues: Other


How do I know the equipment was working properly?

The photo radar operator performs a series of checks to make sure that the equipment is functioning properly before any violations are recorded.  If you decide to contest your case, the City Attorney's Office can provide you records of the set-up and testing performed by the photo radar operator.

How and when is the speed detection system calibrated?

As required by Colorado law, the radar unit that detects speed is calibrated annually at the State's Metrology laboratory.  In addition, the photo radar technician performs tests on a regular basis to ensure the system is operating correctly.

Couldn't the radar beam have detected a vehicle near mine?

No.  The beam on these units is very narrow and so could not have picked up a nearby vehicle.  Also, if two vehicles happen to fall within the beam at the same time, it will not be able to detect the speed for either vehicle.

I have read the Manual on Uniform Traffic Control Devices (MUTCD) and believe that the speed limit where my violation occurred is set too low using MUTCD criteria. Shouldn't my case be dismissed?

No.  The City of Boulder is a "home rule" city and is not required to follow the MUTCD.

I don't believe the school zone light was flashing when my violation occurred.  What should I do?

You may come to court on your court date and discuss this with the prosecutor.  However, officers conducting speed enforcement in school zones are generally very careful about making sure that the lights are flashing before beginning their enforcement.  This may well be a factual issue that can only be decided at a trial.
