The photo speed vans are deployed on residential streets with a posted speed limit of 35 MPH or less; streets bordering parks with any posted speed limit and in school zones throughout the City and County of Denver.  The enforcement deployments are scheduled by the Photo Enforcement Unit supervisor based on best use of resources and complaint areas where photo enforcement is a viable option to reduce speeding and increase traffic safety.

What are the hours of operation of the photo speed vans?

There are currently two shifts scheduled for photo speed enforcements.  The current hours of operations for the photo speed vans encompass these two shift times from 6:00 AM to 9:30 PM. 

Isn't there supposed to be a sign warning of the photo speed vans operating in an area?

Yes.  The state statute governing Automated Vehicle Identification Systems, 42-4-110.5 outlines "….unless there is posted an appropriate temporary sign in a conspicuous place not fewer than three hundred feet before the area in which the automated vehicle identification device is to be used notifying the public that an automated vehicle identification devise is in use immediately ahead."  The photo speed operator is required to post the sign and annotate the distance as measured by a pedometer from the sign to the photo speed van.  In addition they annotate the physical location of the sign and the van and any additional notes they elect relating to the sign and van placement.  The operator also ensures the sign is clear and unobstructed.  The sign may be a sign bolted to another sign in the area or it may be a sandwich board style sign placed on the sidewalk.  The enforcement checklist and related paperwork is reviewed by the Denver Police Department before the processing of any detected violations.
