Texas school zone laws require you to slow to the posted speed, keep handheld wireless devices out of your hands, stop for school buses displaying flashing red lights, and stop for crossing guards, whenever the zone is active. Break any of these rules and you face fines that run higher than ordinary traffic tickets, with penalties climbing steeply if a school bus violation causes injury. Every zone posts its own speed and hours, so the signs at each location are what actually govern you.
Speed Limits and When the Zone Is Active
Most Texas school zones post 20 mph, but the Texas Transportation Code lets municipalities set the limit based on traffic engineering studies, and some zones go as low as 15 mph.1State of Texas. Texas Transportation Code 545.352 – Prima Facie Speed Limits Whatever number is on the sign is the enforceable limit. Don’t assume 20 is safe everywhere.
Zones tell you when the reduced speed applies in one of two ways. The most common is a pair of flashing amber beacons on the speed limit sign; if they’re flashing, the lower limit is in effect. Some zones use changeable message signs or blank-out displays that show the limit only during active periods.2Federal Highway Administration. Manual on Uniform Traffic Control Devices Part 7 – Traffic Control for School Areas The other method is a fixed time window printed on the sign, such as “7:15–8:00 AM” and “3:00–3:45 PM.” If the sign lists times, the reduced limit applies during those windows whether or not you see students.
Hours vary by campus because each district sets its own schedule, and lunch periods can trigger an active window where students cross streets. Watch for the fluorescent yellow-green school zone signs marking where the reduced speed begins, and don’t accelerate until you pass the “END SCHOOL ZONE” sign.3Texas Department of Transportation.

Handheld Phones and Wireless Devices
Two laws stack here. The statewide texting ban prohibits reading, writing, or sending electronic messages while your vehicle is moving, on any road.4State of Texas. Texas Transportation Code 545.4251 – Use of Portable Wireless Communication Device for Electronic Messaging Offense The school zone rule is stricter: it bans all handheld wireless device use, phone calls included, while you’re driving on the property of a public elementary, middle, junior high, or high school during the time a reduced speed limit is in effect.5Texas Public Law. Texas Transportation Code 545.4252 – Use of Wireless Communication Device on School Property Offense
Outside a school zone, you can legally hold your phone for a voice call. Inside an active school zone, picking up the phone at all is a violation unless you’re using Bluetooth or speakerphone. Navigation apps are permitted hands-free. Calls to 911 or law enforcement are exempt. If your vehicle is fully stopped and in park, such as in a pick-up line, the school zone ban doesn’t apply.6Texas School Safety Center. House Bill 347
Many zones post a “CELL PHONE USE PROHIBITED” sign under the speed limit sign, but the law applies whether or not the sign is there.
Stopping for a School Bus
When a school bus turns on its flashing red lights and extends its stop arm, every driver approaching from either direction must stop before reaching the bus and stay stopped. You may not move until the bus starts moving, the driver waves you on, or the red lights shut off.7Texas Public Law. Texas Transportation Code 545.066 – Passing a School Bus Offense
There is one exception. On roads with physically separated roadways, drivers going the opposite direction don’t have to stop. A raised median, unpaved divider, or barrier counts. A painted center turn lane does not. If you could drive across it without hitting a curb or barrier, it isn’t a divided roadway for this rule.7Texas Public Law. Texas Transportation Code 545.066 – Passing a School Bus Offense If you’re unsure whether the road qualifies, stop.
Crossing Guards
When an adult crossing guard steps into the roadway with a STOP paddle, all vehicles must stop. The paddle carries the same legal weight as a traffic control device, and you may not proceed until the guard clears the roadway and signals it’s safe.2Federal Highway Administration. Manual on Uniform Traffic Control Devices Part 7 – Traffic Control for School Areas Where there’s no guard, drivers approaching a marked crosswalk in a school zone must yield to pedestrians crossing or about to cross.
Fines and Penalties
Speeding in a School Zone
School zone speeding is a Class C misdemeanor. Unlike construction zones, where state law expressly doubles the fine, there is no statewide statutory doubling for school zones.8State of Texas. Texas Transportation Code 542.404 – Fine for Offense in Construction or Maintenance Work Zone Even so, most Texas municipalities set school zone fines well above regular speeding tickets, and courts have broad discretion. Typical fines run from roughly $200 to over $500 depending on the city and how far over the limit you were going, plus court costs and surcharges.
Phone and Texting Violations
Penalties depend on which law you broke. A first offense under the statewide texting ban carries a fine of up to $99, with subsequent offenses reaching $200.4State of Texas. Texas Transportation Code 545.4251 – Use of Portable Wireless Communication Device for Electronic Messaging Offense Handheld device use in an active school zone can bring a fine of up to $200.5Texas Public Law. Texas Transportation Code 545.4252 – Use of Wireless Communication Device on School Property Offense If texting while driving causes serious bodily injury, the offense can be elevated to a Class A misdemeanor with a fine of up to $4,000 and up to a year in jail, whether or not it happened in a school zone.
Passing a Stopped School Bus
This is where the penalties escalate hardest. A first offense carries a fine of $500 to $1,250.7Texas Public Law. Texas Transportation Code 545.066 – Passing a School Bus Offense A second offense within five years carries a fine of $1,000 to $2,000, and the court may suspend your driver’s license for up to six months. If the violation causes serious bodily injury, it becomes a Class A misdemeanor punishable by a fine of up to $4,000 and up to a year in jail. A repeat offense causing serious bodily injury is elevated to a state jail felony, with 180 days to two years in a state jail facility.
The six-month license suspension surprises many drivers. It’s discretionary, but the court has full authority to impose it on a second conviction within five years. For anyone whose job depends on driving, that alone is reason enough to wait behind a bus with its lights on.
