A Word About Stop Signs- Arizona traffic law defines a stop as- “Stop, if required, means complete cessation from movement.” While bicyclists and motorists are required to stop at stop signs, it is not necessary to put your foot on the ground to meet the letter of the law. Running stop signs on major streets is extremely dangerous and can result in a fine of $212 with points added to your driver’s license. Running stop signs sets a bad example for younger riders
As you can now see Arizona law doesn't allow bicycle riders to treat stop signs as yield signs. This was taken from the Arizona bicyclist guide to traffic laws.
