Quick reference

Loading and Unloading Students

  • Activate amber warning lights at least 100 feet before the school bus stop when approaching to load or unload students.

  • Stop the bus so students do not have to cross the roadway whenever the road layout and stop location allow; if crossing is unavoidable, the driver signals the crossing.

  • Students must cross at least 10 feet in front of the bus and wait for the driver's hand signal before entering the roadway.

  • Red lights and the stop arm are activated only when students are actually loading or unloading, not during a stop with no student movement.

  • Count students as they exit and again after they clear the danger zone; the driver confirms no student remains before moving.

  • The danger zone extends 10 feet around the bus on all sides; students inside it must be visible to the driver at all times.

  • Deactivate red lights and stop arm, then verify all students are seated or clear of the bus, before releasing the parking brake.

  • On multi-lane roads, drivers should not use the stop arm and red lights to halt traffic when students do not need to cross and a safer curbside stop exists.

  • Minnesota requires school bus drivers to ensure students are seated before the bus moves; the driver is responsible for safe loading and unloading at each stop.

Quick reference

Student Management and Discipline

  • Driver authority over students exists while students are on the bus and while they are boarding or leaving; discipline is limited to reasonable, non-physical measures.

  • A driver may not use physical force except to protect students or others from imminent harm; corporal punishment is prohibited.

  • Report serious misconduct to the school district in writing; districts maintain the authority to suspend a student's bus-riding privileges.

  • Assign seats when behavior problems persist; documented seating assignments support later discipline decisions.

  • Distractions from passengers are a leading cause of crashes; the driver stops the bus in a safe location to address serious disruptions rather than managing them while moving.

  • Threats, weapons, or fighting require stopping the bus, securing students, and notifying dispatch and law enforcement.

  • Explain rules at the start of the year and reinforce them consistently; documented rule explanations support enforcement.

  • Bullying and harassment on the bus fall under school district policy and Minnesota anti-bullying requirements; the driver documents and reports incidents.

Quick reference

Railroad-Highway Grade Crossings

  • Stop the school bus at every railroad-highway grade crossing, whether or not a train is visible, unless the crossing is exempted and posted.

  • Stop no closer than 15 feet and no farther than 50 feet from the nearest rail.

  • Turn off all radios and fans, open the service door and driver's window, and listen before crossing.

  • Look and listen in both directions; if a train is approaching, remain stopped and do not attempt to cross.

  • Cross in a gear that allows completing the crossing without shifting; never shift gears while on the tracks.

  • Check that the bus has enough space and clearance on the far side to fully clear the crossing before proceeding.

  • If the bus stalls on the tracks, evacuate students immediately and move them at least 100 feet away from the tracks, then call 911.

  • Report any crossing signal malfunction or blocked view to dispatch and the railroad; do not cross if signals are activated.

Quick reference

Emergency Evacuation and Safety Procedures

  • Evacuate only when staying aboard is more dangerous than leaving: fire, fuel leak, hazardous material, or a bus in a dangerous position.

  • Front door evacuation is used for most emergencies; rear door is used when the front door is blocked or a fire is near the front.

  • Rear door evacuation requires the driver to exit first and assist students as they come down; two students may exit side by side.

  • Evacuation drills must be conducted at least twice per school year in Minnesota, with one drill in the first weeks of school.

  • Students evacuate at least 100 feet from the bus and upwind of a fire or spill, then assemble at a designated point for a head count.

  • The driver takes the emergency kit, fire extinguisher, and first aid kit if safe to do so, and leaves the bus in neutral with parking brake set.

  • Emergency exits include the rear door, side windows, roof hatches, and emergency door; drivers must know the operation of each on their assigned bus.

  • After evacuation, account for every student by name and report missing students to responding emergency personnel.

Quick reference

Vehicle Inspection and Pre-Trip Checks

  • A pre-trip inspection covers brakes, steering, lights, tires, mirrors, emergency exits, stop arm, crossing gate, and horn before every trip.

  • Check tire tread depth and inflation; Minnesota requires at least 4/32 inch tread on front tires and 2/32 inch on other tires for commercial vehicles.

  • Test brake system with a static air-brake check if equipped; check for air pressure loss and low-pressure warning.

  • Verify all required lights work: headlights, taillights, brake lights, turn signals, hazard lights, clearance lights, and the eight-way warning lamp system.

  • Confirm emergency equipment is present and charged: fire extinguisher, first aid kit, body fluid cleanup kit, and emergency triangles.

  • Check mirrors are adjusted for the driver's seating position and provide a clear view of the danger zone around the bus.

  • Inspect the stop arm and crossing gate for full extension and retraction; a defective stop arm removes the bus from service.

  • Post-trip inspection is required at the end of each route to check for sleeping or left-behind students and to report defects.

School Bus Driving Fundamentals and Safe Operation

  • Use the eight-way warning light system: amber lights warn of an approaching stop, red lights and the stop arm require traffic to stop.

  • Maintain a following distance of at least one second per 10 feet of vehicle length plus one second; for a 40-foot bus at 40 mph, that is at least 5 seconds.

  • Reduce speed in rain, snow, and ice; stopping distance on ice can be many times longer than on dry pavement.

  • Use the crossover and convex mirrors to monitor the danger zone; adjust and check mirrors before each stop.

  • Back only when necessary; use a spotter if available, and if not, check all mirrors and the rear area before backing.

  • Do not tow or push a school bus; do not allow students to stand or move while the bus is in motion.

  • At intersections, look left-right-left and yield to traffic already in the intersection; school buses are not exempt from right-of-way rules.

  • Use engine braking and lower gears on downgrades; avoid continuous service brake use that can cause brake fade.

  • Load and unload only at designated stops; avoid stopping on curves, hill crests, or where visibility is limited.

Quick reference

Special Stops

  • At a school bus stop, activate amber lights, slow down, and stop so the bus is visible to approaching traffic in both directions.

  • On a divided highway with a median or barrier, a school bus stopping to load or unload does not require traffic on the opposite side to stop.

  • At an intersection, stop before the crosswalk and activate red lights only when students are actually crossing or loading.

  • When stopping at a railroad crossing, do not activate the stop arm; use hazard lights if needed to warn traffic.

  • For stops at a student's home, pull as far off the roadway as practical and ensure students can reach the door without entering traffic.

  • Never stop on a railroad track, bridge, or in an intersection; choose a safe location even if it means walking students a short distance.

  • At a bus stop on a curve or hill, use a spotter or an alternate location; visibility is critical to preventing rear-end crashes.

  • When a student is late, do not wait beyond the scheduled time; report the missed stop to dispatch.

Quick reference

Crossing and Hazard Awareness

  • Scan 12 to 15 seconds ahead of the bus and check mirrors every 5 to 8 seconds while driving.

  • Identify hazards early: pedestrians, cyclists, parked cars, driveways, and school zones with children present.

  • Children are unpredictable; reduce speed in school zones and near playgrounds and be ready to stop.

  • At intersections, scan for vehicles running red lights or stop signs before entering the intersection.

  • In fog, rain, or snow, reduce speed and increase following distance; use low-beam headlights, not high beams, in fog.

  • Watch for ice on bridges, overpasses, and shaded areas; these freeze before the surrounding roadway.

  • When a vehicle passes a stopped school bus illegally, do not pursue; record the plate and report to law enforcement.

  • Use the danger zone concept: children within 10 feet of the bus are at highest risk, especially during loading and unloading.

Quick reference

Post-Crash and Incident Response

  • Stop immediately after a crash, protect the scene, and check students for injuries before moving anyone unless there is fire or other danger.

  • Call 911 and report location, number of students, injuries, and whether the bus is blocking traffic.

  • Do not move injured students unless they are in immediate danger; wait for emergency medical personnel.

  • Set out warning triangles or flares when safe to do so, and turn on hazard lights.

  • Exchange information with other drivers and notify dispatch and the school district immediately.

  • Document the scene: photographs, witness names, and a written account of what happened.

  • Evacuate the bus only if there is fire, hazardous material, or a dangerous position; otherwise keep students aboard until responders arrive.

  • After any crash, the driver is subject to post-crash testing requirements under federal and state rules, including alcohol and drug testing when applicable.

Quick reference

Minnesota-Specific School Bus Laws and Rules

  • Minnesota law requires vehicles to stop for a school bus with red lights flashing and stop arm extended on undivided roads; violators face criminal penalties.

  • On a divided highway with a median or physical barrier, traffic on the opposite side of the median is not required to stop.

  • School bus drivers must hold a valid CDL with passenger and school bus endorsements and meet Minnesota physical qualification requirements.

  • Minnesota school bus drivers must complete pre-service training and annual in-service training, including emergency evacuation drills.

  • School buses must stop at all railroad crossings except where exempted and posted by the state or local authority.

  • The school bus stop arm may be used only when students are loading or unloading; misuse is a violation of state rules.

  • Minnesota requires school bus drivers to report certain convictions and disqualifying offenses to the employer and the state.

  • Districts must adopt and enforce student transportation policies, including bus conduct rules and consequences.
