Independent Safety Information
& Official Records
School bus safety involves more than the bus itself. Student loading and unloading, driver behavior, surrounding traffic, roadway conditions, visibility, enforcement, technology, and state requirements all play a role.
Gardian Angel maintains this resource library to make relevant safety research, government guidance, public records, and transportation resources easier to find in one place.
The resources below come from federal agencies, state transportation organizations, national pupil transportation organizations, and other authoritative sources. They are provided for informational purposes and are intended to help transportation professionals, policymakers, school districts, and others research school bus safety.
Unless otherwise stated, links should direct visitors to the original source maintained by the applicable government agency or organization. Gardian Angel does not independently verify every statement contained in an external source and does not provide legal, regulatory, engineering, or safety advice through this page.
Federal Safety & Policy
Federal law and federal safety agencies provide an important foundation for understanding school bus safety technology, student pedestrian safety, and illegal school bus passing.
Infrastructure Investment & Jobs Act
Public Law 117-58 | Section 24110
The bipartisan Infrastructure Investment and Jobs Act directs the U.S. Department of Transportation to review and evaluate technologies that may enhance school bus safety, including cameras, audible warning systems, and enhanced lighting.
The law also calls for an assessment of the effectiveness of school bus lighting systems in clearly communicating to surrounding drivers the appropriate actions they should take.
This provision establishes a federal direction to evaluate school bus safety technologies. It does not constitute an approval, certification, or endorsement of any particular product or manufacturer.
NHTSA:
School Bus Safety
The National Highway Traffic Safety Administration provides national information on school bus safety, including illegal passing, school bus lights, student loading and unloading, and safety around the school bus.
NHTSA notes that children face particular risk when approaching or leaving a school bus and when crossing the roadway.
NHTSA: Reducing the Illegal Passing of School Buses
NHTSA’s guidance examines illegal school bus passing through a broader Safe System Approach and discusses strategies involving enforcement, engineering, education and awareness, and policy.
The guide also identifies engineering approaches that can make school buses more visible to motorists, including additional exterior lighting and other engineering countermeasures.
The discussion of a technology or countermeasure in an external government publication should not be interpreted as an endorsement of Gardian Angel or any other specific product.
NHTSA: Understanding School Bus Lights
NHTSA explains the purpose and meaning of school bus warning lights and the actions expected of surrounding motorists when a school bus is preparing to stop or is stopped for students.
School bus lighting requirements and permitted configurations may vary by jurisdiction. Visitors should consult the applicable state and local requirements before relying on any general description of school bus lighting.
NTSB Investigations
& Recommendations
The National Transportation Safety Board investigates transportation crashes and issues safety recommendations when improvements are identified.
These resources provide primary-source information concerning school bus pedestrian safety, illegal passing, roadway crossings, and safety-enhancing technologies.
Rochester, Indiana School Bus Crash
NTSB Investigation HWY19MH003 | HAR-20-02
On October 30, 2018, four children were struck while crossing a 55-mph roadway to board a stopped school bus in Rochester, Indiana. Three children were fatally injured and one was seriously injured.
The NTSB investigation identified safety issues involving school bus routes and stops, motorists failing to respond appropriately to a stopped school bus, and the need for greater use of technologies to prevent collisions with and mitigate injuries to student pedestrians.
The investigation and final report should be reviewed in full for the NTSB’s findings, probable cause, and safety recommendations.
NTSB Safety Recommendation H-20-011
Following the Rochester investigation, the NTSB recommended that NHTSA:
“Evaluate the effectiveness of technologies designed to reduce the incidence of illegal school bus passings, and publish and disseminate the evaluation results.”
The recommendation addresses the evaluation of technology as part of a broader effort to reduce illegal school bus passing.
Status: Open - Unacceptable Response
Because recommendation status may change, the current NTSB recommendation page should be treated as the controlling source.

National Data & Research
Understanding the problem requires reliable information. These resources provide national and historical data concerning school bus loading and unloading incidents, fatalities, traffic crashes, and illegal school bus passing.
National School Bus Loading & Unloading Surveys
The National School Bus Loading and Unloading Survey provides historical information concerning students killed while loading or unloading school buses, including incidents involving passing motorists.
Survey information may include factors such as student age, roadway conditions, location around the bus, lighting conditions, weather, roadway type, and other circumstances surrounding loading and unloading incidents.
Historical survey data may use definitions, collection methods, and reporting periods that differ from other national datasets. Visitors should review the methodology and limitations provided with each source.
NHTSA Fatality Analysis Reporting System
NHTSA’s Fatality Analysis Reporting System, commonly known as FARS, provides national traffic fatality data collected from qualifying fatal crashes.
FARS is a crash-fatality database and should not be treated as a complete record of every school bus incident, near miss, injury, or illegal passing event
National Illegal Passing Data
National Association of State Directors of Pupil Transportation Services surveys have documented the continuing scale of illegal school bus passing across the United States.
NHTSA’s current guidance references an estimated
43.5 million illegal school bus passes during the 2022-2023 school year, based on the national survey.
This figure is an estimate derived from survey methodology and should be presented with the source, survey period, and applicable limitations. It should not be described as a direct count of every illegal pass nationwide.
