Texas School Zone Laws: Speed Limits, Hours, and Penalties

Few traffic tickets sting as much as a school zone violation. The fines are steep, the speed limits are low, and every parent who’s ever gotten one has said the same thing: “I didn’t even realize the zone was active.” If you’ve been tagged for speeding in a Texas school zone — or you want to avoid it — here’s everything you need to know about how school zones work in Texas, what the penalties are, and how to handle a ticket.

How School Zones Work in Texas

A school zone is a designated area around a school where reduced speed limits apply during specific times. In Texas, school zones are established by local jurisdictions (cities, counties, or TxDOT for state-maintained roads) and are marked by regulatory signs and, in most cases, flashing warning lights.

The typical Texas school zone speed limit is 20 mph, though some zones post 15 mph. The reduced speed applies only during active periods — not 24 hours a day.

School zones are governed by Texas Transportation Code § 545.352, which gives local authorities the power to establish reduced speed zones near schools and sets the framework for enforcement.

When Are School Zones Active?

This is where most confusion — and most tickets — happen. School zones are active under one of two systems:

Flashing light system: Most Texas school zones use flashing yellow or amber lights mounted on the school zone sign. When the lights are flashing, the reduced speed limit is in effect. When they’re not flashing, the regular speed limit applies.

Posted time system: Some school zones — particularly in rural areas or smaller towns — don’t have flashing lights. Instead, the sign lists specific times (for example, “School Zone 7:00 AM – 8:30 AM and 2:30 PM – 4:00 PM”). During those posted hours, the reduced speed limit applies regardless of whether you see children or activity.

The key point: if the lights are flashing or you’re within the posted time window, the school zone speed limit is in effect. It doesn’t matter if school appears to be out, if there are no children visible, or if it’s a holiday. If the lights are flashing, you slow down.

What Defines a School Zone?

A school zone in Texas typically extends for a specific distance along a road adjacent to a school property. The zone begins at the first school zone sign and ends at the sign indicating the end of the school zone (or a sign resuming the regular speed limit).

Most school zones cover 200 to 400 feet along the road near the school entrance, crosswalks, or areas where children congregate. Some zones are longer, particularly near schools with multiple driveways or large campuses.

Not every school has a school zone. The decision depends on traffic volume, road speed, proximity of the school to the roadway, and pedestrian crossing patterns. Private schools, day care centers, and charter schools may or may not have school zones depending on local decisions.

Penalties for School Zone Violations

Texas takes school zone violations seriously, and the penalties reflect that:

Speeding fines are doubled. Whatever the fine would be for speeding on a regular road, it doubles in a school zone. A ticket for going 35 in a 20 mph school zone can easily cost $300 to $400 after court costs.

Points on your driving record. A school zone speeding ticket adds points to your Texas driving record, just like any other speeding ticket.

Insurance increases. Insurance companies view school zone violations as particularly risky. A school zone speeding conviction can increase your premiums more than a standard speeding ticket.

Cell phone violations. Using a handheld device in an active school zone is a separate violation on top of any speeding ticket. Under Texas cell phone law, all handheld device use is banned in active school zones.

Cell Phone Ban in School Zones

While the statewide texting ban only prohibits electronic messages, school zones have a much stricter standard. In an active school zone, you cannot use a handheld wireless communication device for any purpose — no calls, texting, GPS, music apps, or any other phone activity requiring holding the device.

Hands-free devices are permitted. Bluetooth earbuds, a mounted phone operated by voice, or your car’s built-in system are all fine. The restriction is specifically on holding the phone.

Getting caught using a handheld device in a school zone results in a fine on top of any speeding ticket — and the phone violation itself can range from $100 to $200.

Can You Dismiss a School Zone Ticket With Defensive Driving?

Yes, in most cases. School zone speeding tickets are typically eligible for defensive driving dismissal. Contact your court within the deadline on your citation. Request permission to take a defensive driving course. Complete the course within the allowed timeframe. Submit your certificate and driving record to the court.

Given the doubled fines and insurance impact, defensive driving is an especially good deal for school zone violations. You can only use it once every 12 months in Texas, so check your eligibility first.

Tips for Avoiding School Zone Tickets

Know your route. If you drive the same roads daily, note where the school zones are and when they’re active. Watch for signs. Yellow diamond-shaped signs with children pictured precede every school zone. Check the lights. Flashing means active — slow to 20 mph. Give yourself extra time. Rushing through school zones is how most tickets happen. Put your phone away. Use hands-free or wait until you’re clear of the zone.

Frequently Asked Questions

What is the speed limit in a Texas school zone?

Most Texas school zones post a speed limit of 20 mph, though some use 15 mph. The reduced limit only applies when the school zone is active — either when flashing lights are on or during posted hours.

Are school zone fines doubled in Texas?

Yes. Texas law doubles speeding fines in active school zones. A speeding ticket that might cost $150 on a regular road could cost $300 or more in a school zone, plus court costs and fees.

Can I use my phone in a school zone in Texas?

Only with a hands-free device. Texas law bans all handheld wireless device use in active school zones — no calls, texting, or any other handheld phone activity.

Are school zones active during summer in Texas?

School zones using flashing-light systems are typically not active during summer, as the lights are synced to the school calendar. However, zones using posted-time signs may technically be active year-round. Enforcement during non-school periods is rare.

How much is a school zone speeding ticket in Texas?

Total fines (including court costs) for school zone speeding typically range from $250 to $500+. Because fines are doubled, school zone tickets are significantly more expensive than regular speeding tickets. Defensive driving is almost always the most cost-effective way to handle one.
