Photo Radar Enforcement Laws in Arizona

Photo Radar Enforcement in Arizona

Following Arizona law, photo enforcement systems must be clearly marked in the view of motorists.

Failure to properly warn motorists can often lead to a driver being acquitted from an unjust ticket.

In order for a photo radar ticket to be justified, the following laws must be followed:

  1. There must be at least 2 signs placed in a location ahead of the photo radar system. The first sign has to be at least 300 feet before the system and additional signs shall be more than 300 feet before the system. This provides reasonable warning for drivers to notice that a photo enforcement system is in place.
  2. If the photo enforcement system is not currently present or operation, the signs must be removed or covered.
  3. The signs put up by a local authority or Arizona agency must contain a yellow warning notice.

These laws apply to all Arizona photo radar enforcement systems, whether they are stationary systems or mobile photo radar vehicles.

The exception for mobile photo radar vehicles is that if they are stationed on a stress where the posted speed limit is less than 40mph, “[The above laws do not] apply to a mobile photo enforcement vehicle during the time a mobile photo enforcement vehicle is deployed on streets with a posted speed limit of forty miles per hour or less”.

This means that if there is a posted speed limit higher than 40mph, there must be two signs with yellow warning notices.
