Other maximum speed limits established by law include:

  • 25 mph limit on local streets in residential areas and business districts
  • 15 mph limit in alleys
These speeds may not always be posted, but you are required to know these basic speed laws.

Speed limits approaching yellow school crosswalks are 15 mph when the portable signs are placed on the street.

When a speed limit sign is not posted, Arizona's Basic Speed Law applies. It requires you to drive at a speed that is reasonable and prudent under existing conditions.

In every event, speed must be so controlled as to avoid colliding with any object, person, or vehicle on the highway.

It is the duty of ALL drivers to exercise reasonable care for the protection of others.
