The Arizona school zone speed limit is 15 miles per hour, and it applies between the portable signs placed at an authorized school crossing while school is in session. The rule comes from A.R.S. 28-797, and violating it costs you double the standard speeding fine. Push past 35 mph in one of these zones and the ticket becomes a criminal misdemeanor rather than a civil citation.1Arizona Legislature.

When the 15 MPH Limit Applies
The 15 mph limit is not a round-the-clock rule and it is not tied to the general area around a school. It applies only between the portable signs that mark an authorized school crossing, and only while school is in session, which the statute defines as school hours plus the periods when children are arriving or leaving at opening and closing times.1Arizona Legislature. Arizona Code 28-797 – School Crossings; Civil Penalty; Assessment; Definition
The law is not limited to elementary schools. Any school with an authorized crossing can activate the 15 mph zone. On weekends, holidays, and summer break, the normally posted speed limit governs instead.
Cities and towns sometimes set their own reduced limits, like 25 or 35 mph, in the broader area around a school. Those are separate from the 15 mph rule and follow whatever signage is posted for them.
How to Tell the Zone Is Active
The portable signs are what matter. School authorities place them in the roadway before the school session begins and remove them within one hour after the session ends.1Arizona Legislature. Arizona Code 28-797 – School Crossings; Civil Penalty; Assessment; Definition If those signs are out, the 15 mph limit is in effect whether or not you see any children nearby. If they are not out, it is not.
The signs must be placed no more than 300 feet from each side of the crossing, so the enforceable zone runs a maximum of 600 feet end to end. The signs also state that passing is prohibited inside the zone, that drivers must stop for anyone in the crosswalk, and that fines are doubled. Passing another vehicle anywhere between the signs is illegal.
Yellow pavement markings at the crosswalk and yellow center-line markings on the roadway reinforce where the crossing itself sits.2Arizona Department of Transportation. Better Safe Than Sorry: Arizona School Zones Aim to Provide Safe Crossings
Doubled Fines for a Civil Violation
When the portable signs are displayed with language stating that the civil penalty will double, that is exactly what happens. You pay the standard civil penalty for the speed you were driving, plus an additional assessment equal to that penalty.1Arizona Legislature. Arizona Code 28-797 – School Crossings; Civil Penalty; Assessment; Definition
Base civil fines for speeding in Arizona vary with how far over the limit you were driving. A driver a few miles over might face a base fine around $140, while someone 20 or more over could see base fines closer to $400 or $500. Double those numbers in a school zone. Arizona also adds a 13% surcharge to traffic fines, calculated on the base fine before the doubling. A school zone speeding ticket routinely runs several hundred dollars.
Failing to stop when a person is in the crosswalk is a separate violation under the same statute, and the same doubled-penalty structure applies.
Criminal Speeding at 35 MPH or More
Speed matters differently once you cross 35 mph near a school crossing. Under A.R.S. 28-701.02, exceeding 35 mph near a school crossing is criminal speeding, a Class 3 misdemeanor.3Arizona Legislature. Arizona Code 28-701.02 – Excessive Speeds; Classification The threshold is 35 mph total, not 35 over the posted limit. In a 15 mph zone, that means 20 over is enough to make the charge criminal.
A Class 3 misdemeanor carries up to 30 days in jail and a fine of up to $500, plus surcharges.4Arizona Legislature. Arizona Code 13-707 – Misdemeanor Sentences5Arizona Legislature. Arizona Code 13-802 – Fines A conviction also becomes a permanent criminal record visible to employers, landlords, and licensing boards. Defensive driving school cannot resolve a criminal charge.
Dismissing a Ticket Through Defensive Driving
For a civil school zone speeding ticket under A.R.S. 28-797, Arizona lets you attend a defensive driving course to keep the violation off your record and avoid points on your license.6Arizona Judicial Branch. List of Eligible Violations For most drivers this is the best available outcome, so the eligibility rules matter.
You cannot use the course if you attended one for another eligible violation within the 12 months before your current violation date, if the incident involved a serious injury or fatal accident, or if you are trying to dismiss more than one violation at once.7Arizona Judicial Branch. Defensive Driving Schools Commercial license holders may attend only if they were driving a personal vehicle requiring a standard Class D or Class M license.
The deadline is firm. You must complete the course no later than seven days before your scheduled court date, and the school checks eligibility after you register, not before. Sign up early.
Points, Insurance, and the Real Cost
A speeding conviction adds 3 points to your Arizona driving record. Enough points can trigger mandatory traffic survival school or, at higher totals, license suspension.
Insurance is where a school zone ticket keeps costing you. A conviction signals higher risk to insurers, and rate increases of 20% or more are common. Most auto insurers look back three to five years, so a single ticket can add well over a thousand dollars in premium over that window. Add the doubled fine, surcharges, and possible defensive driving course fees, and even a civil school zone ticket can total $1,500 to $2,000 before it fully clears your record.
