School Zone Driving in the Inland Empire: Rules and Tips
School zone driving in the Inland Empire follows California state law. The speed limit is 25 mph within 500 feet of a school while children are outside or crossing, and some zones are as low as 15 mph. You must stop for a school bus flashing red lights, obey crossing guards, and yield to pedestrians in crosswalks. Teens with a provisional license have extra limits, and Caltrans QuickMap helps you check I-10 and I-215 first.
Picture a parent in Rancho Cucamonga with a morning drop-off, a newly licensed teen and a freeway commute. Here is what the rules say.
Key takeaways
- The school zone speed limit is 25 mph within 500 feet of a school while children are outside or crossing, and some zones are as low as 15 mph.
- Since January 1, 2026, local authorities may lower school zone limits from 25 to 20 mph. Starting January 1, 2031, 20 mph becomes the school zone limit where posted signs and their conditions apply.
- Stop for a school bus flashing red lights from either direction, unless it is on the other side of a divided or multilane highway.
- For the first 12 months, provisional drivers cannot drive between 11 p.m. and 5 a.m. or carry passengers under 20 without a qualified adult.
Why School-Year Driving Deserves Attention
According to the National Highway Traffic Safety Administration (NHTSA), "In 2024, 7,080 pedestrians were killed and more than 71,000 pedestrians were injured nationwide." NHTSA's advice to drivers includes following the speed limit, "especially around people on the street, in school zones and in neighborhoods where children are present".
NHTSA's school bus safety page reports fatalities in school-transportation-related traffic crashes fell from 128 in 2023 to 110 in 2024.
School Zone Speed Limits in California
The basic rule is in Vehicle Code 22352. It sets a 25 mph limit when approaching or passing a school building or grounds posted with a standard "SCHOOL" warning sign, while children are going to or leaving the school during school hours or the noon recess. Those signs may be placed up to 500 feet from school grounds.
The California Driver Handbook adds: "Some school zones may have speed limits as low as 15 mph."
Where 15 mph can apply
Under Vehicle Code 22358.4, local authorities may set a 15 mph limit in a school zone in a residence district, on a highway with a posted limit of 30 mph or slower and no more than two traffic lanes. They may also set 25 mph at a distance of 500 to 1,000 feet from a school zone.
The 20 mph law
The California Highway Patrol says Assembly Bill 382 "allows local authorities to lower the school zone speed limit from 25 to 20 miles per hour by ordinance or resolution through January 1, 2031". After that, CHP says, the limit "will automatically decrease from 25 to 20 miles per hour in school zones when proper signage is posted". The DMV lists the same 2031 date.
School Buses: Yellow Lights and Red Lights
The Driver Handbook explains that some school buses flash yellow lights when preparing to stop, and "The yellow flashing lights warn you to slow down and prepare to stop."
When the bus flashes red lights, the handbook says "you must stop from either direction until the children are safely across the street and the lights stop flashing". Vehicle Code 22454 requires you to stay stopped until the flashing red light signal and stop arm, if the bus has one, cease operation.
The exception: you do not need to stop if the bus is on the other side of a divided or multilane highway, meaning two or more lanes in each direction. The handbook warns, "If you fail to stop, you may be fined up to $1,000 and your driving privilege could be suspended for one year."
NHTSA advises children to walk at least "ten feet" in front of the bus before crossing, so expect them there and wait.
Crossing Guards and Crosswalks
For crossing guards, the handbook's advice is short: "Be sure to obey their directions at all times." Under Vehicle Code 2815, disregarding a traffic signal or direction from an authorized nonstudent school crossing guard wearing official insignia near a school is an infraction.
The Driver Handbook also says "Pedestrians have the right-of-way in marked or unmarked crosswalks" and tells drivers not to pass a vehicle stopped at a crosswalk.
Check I-10 and I-215 Before You Leave
Caltrans QuickMap is a statewide map of real-time traffic cameras, lane closures and road conditions, so use it to check I-10 and I-215 before the school run. Its FAQ lists "traffic speed, lane and road closures due to construction and maintenance activities, incident reports, Changeable Message Sign (CMS) content, camera snapshots, and active chain control requirements."
Check it before you leave, not while you drive. Caltrans notes that in California, "drivers 18 and older can only use their phones in a hands-free manner".
Teen Drivers: Provisional License Rules
The DMV's teen driver page says a teen must hold a permit for at least 6 months before the driving test and complete 50 hours of supervised practice, with 10 hours at night.
Under Vehicle Code 12814.6 and the Driver Handbook, during the first 12 months with a provisional license, a teen cannot drive:
- Between 11 p.m. and 5 a.m.
- With passengers under 20 years old, unless a parent, guardian, California-licensed driver at least 25 years old, or licensed driving instructor rides along.
There are exceptions, each with a signed note. For school, a teen may drive "for schooling or a school activity" with a note signed by the principal, dean or designee. Other exceptions cover medical need, work and family. These exceptions allow driving between 11 p.m. and 5 a.m. or carrying an immediate family member. They do not allow carrying other passengers under 20.
Phones are off limits for teens. Vehicle Code 23124 bars drivers under 18 from using a wireless phone or electronic wireless communications device while driving, "even if equipped with a hands-free device," except in emergencies.

Frequently Asked Questions
What is the school zone speed limit in California?
Under Vehicle Code 22352, it is 25 mph when approaching or passing a school with a posted "SCHOOL" sign while children are going to or leaving school. The DMV notes some zones are as low as 15 mph, and AB 382 lets local authorities lower limits to 20 mph.
Do I have to stop for a school bus on the other side of the road?
Usually, yes. The DMV says to stop from either direction when a bus flashes red lights. You do not need to stop if the bus is on the other side of a divided or multilane highway with two or more lanes in each direction.
Can a teen with a provisional license drive friends to school?
Not if the friends are under 20, during the first 12 months, unless a parent, guardian, licensed driver 25 or older, or licensed driving instructor rides along. The signed-note exceptions for school, work, medical need and family allow night driving or carrying an immediate family member, not friends.
