Do You Have to Stop for a School Bus in Idaho? Law and $300 Fine

informational·how to guide·Published October 16, 2026·Updated October 20, 2026

When do you have to stop for a school bus in Idaho, and what is the fine?

In Idaho, you must stop before you reach a school bus that is stopped on the road with its visual signals (flashing red lights) on. This applies when you meet the bus or come up behind it. A first offense is an infraction with a $300 fine and 4 points. The one exception: oncoming traffic on a highway of more than 3 lanes.

Where the Idaho school bus law facts come from

The stop rule, the fines and the lane exception come from Idaho Code 49-1422. The points come from IDAPA rule 39.02.71 on the Idaho Administrative Rules site. The plain-language advice comes from the Idaho Driver's Handbook of the Idaho Transportation Department (ITD). The light and stop arm details come from Idaho Code 49-915, the report steps from Idaho Code 49-1423, and the school zone rule from Idaho Code 49-1401 and House Bill 570 (2026). The crash numbers come from an ITD news release of October 19, 2026. All facts are as of 2026. Confirm the rules with the Idaho Transportation Department DMV (itd.idaho.gov/dmv) or your county driver's license office before you drive.

When must you stop for a school bus in Idaho?

If you meet a school bus or come up behind one, and the bus is stopped on the highway with its visual signals on, you must stop before you reach it. The law says "from either direction," so a bus ahead of you and a bus coming toward you both make you stop.

Then you wait. You may not move until the bus starts to move again or its visual signals go off. The Idaho Driver's Handbook adds that you stay stopped until all children are clear of the road and the bus. Test yourself with our free question about what to do behind a stopped school bus.

What signals does an Idaho school bus show when it stops?

Yellow lights come on first. The bus driver must show them at least 200 feet before each stop where the red lights will flash. Slow down and get ready to stop.
Two alternately flashing red lights show at the front of the bus and two at the rear. They must be visible at 500 feet in normal sunlight.
A red stop arm with a silver white border swings out on the left side of the bus, opposite the driver's seat.
The words SCHOOL BUS show on the front and rear in letters at least 8 inches high.

Do you stop on a four-lane road in Idaho?

You drive in the same direction as the bus, on any road

You stop. The exception is only for oncoming traffic, so it never applies when you come up behind the bus.

You drive toward the bus on a highway of more than 3 lanes

You do not have to stop. Idaho Code 49-1422 says oncoming traffic on a highway of more than three lanes is not required to stop. Slow down and watch for children near the bus stop. Try the free question on a school bus on a four-lane road.

You drive toward the bus on a road of 3 lanes or fewer

You stop. The exception applies only to highways of more than 3 lanes.

What is the penalty for passing a stopped school bus in Idaho?

What is the penalty for passing a stopped school bus in Idaho?
Offense	Type	Penalty
First offense	Infraction	$300 fine
Second or later offense within 5 years	Misdemeanor	$600 to $1,000 fine, or up to 6 months in county jail, or both
Any conviction	Driving record	4 points

How do the 4 points affect your license?

A conviction under Idaho Code 49-1422 adds 4 points to your Idaho driving record. That is the top of the 1-to-4 range for a moving violation. Under IDAPA 39.02.71, a driver with 12 or more points in any 12 months gets a 30-day suspension. An approved defensive driving class can remove 3 points, but only once every 3 years.

After a conviction, ITD must tell you about the penalties for a second conviction. For the full point rules and the rules for teen drivers, see our guide to Idaho driving points and teen penalties.

What happens after a bus driver sees a violation?

1
The bus driver writes a report
The driver uses a form from the State Department of Education. It lists the time, the place, the license plate number and a description of the vehicle.
2
The report goes to a peace officer
The bus driver or a school official must deliver it within 72 hours of the alleged violation.
3
The officer starts an investigation
This must start within 7 calendar days after the officer gets the report. The officer contacts the registered owner of the vehicle.
4
The owner names the driver, if needed
If the owner says he or she was not driving, the officer asks the owner to say who was.
5
The officer may write a citation
If the officer can identify the driver and has reasonable cause, the officer writes a uniform traffic citation. It is served in person or by certified mail.

Is there a separate school zone speed rule in Idaho?

Yes, and it is a different rule from the bus law. Since July 1, 2026, driving more than 20 mph over the posted speed limit in an active school zone, when children are present and visible, is reckless driving under Idaho Code 49-1401. A first conviction is a misdemeanor. The judge may order up to 6 months in jail, a fine of up to $1,000, or both. Practice this rule with our free question on speeding in an active school zone.

Key takeaways

Stop before you reach a stopped school bus with its visual signals on. This applies from either direction.
Stay stopped until the bus moves or its signals go off, and until all children are clear of the road and the bus.
Oncoming traffic on a highway of more than 3 lanes does not have to stop. Traffic that goes the same way as the bus always stops.
A first offense is a $300 fine and 4 points. A second offense within 5 years is a misdemeanor with a $600 to $1,000 fine, or up to 6 months in jail, or both.

Idaho school bus law: common questions

Does a school bus use its red lights at every stop?

No. In Idaho, the bus driver may turn on the red lights and stop arm only when the bus is stopped on the highway to pick up or drop off school children. The driver may not use them in business districts that the state or local authorities designate, where traffic signals or peace officers control traffic, or in school bus loading areas where the bus is fully off the road.

Do Idaho school buses have stop arm cameras?

Idaho law sets up a school bus camera fund. The part of each school bus fine above $100 goes into it, so $200 of a $300 first-offense fine. The money may pay only for stop arm software, equipment and training to enforce the stop law. The State Department of Education oversees the fund. Ask your school district if its buses carry cameras.

Can someone else get the ticket if they drove my car past a school bus?

The ticket goes to the driver. When a bus driver reports a plate number, the officer contacts the registered owner. If you say you were not driving, the officer asks you to name the driver. If the officer can identify the driver and has reasonable cause, the citation goes to that driver, in person or by certified mail.

How many school bus crashes happen in Idaho?

ITD reports 86 school bus crashes in Idaho in 2025, with more than $10 million in economic costs statewide. In those crashes, 96% of the people on the buses were not injured. The worst injuries and deaths in school bus crashes usually happen to the people in the other vehicles.
