School bus driver screening questions: S and P endorsements, state certificates and student safety
On this page
School bus driver screening questions should confirm the CDL first: the right class, both the passenger (P) and school bus (S) endorsements or a plan to earn them through entry-level training, and any restriction that limits where or what they can drive. Then check the state's own school bus requirements (certificate, training hours, fingerprinting, minimum age), consent to drug and alcohol testing and the Clearinghouse query, and the split shift. Only after that does it make sense to talk about loading zones, railroad crossings and a bus full of students, which is where the job is won or lost.
This page is for school districts, school bus contractors and recruiters. Commercial freight driving follows a different set of rules and questions; use the truck driver screening questions for those roles. School bus drivers are often recruited alongside other school staff, so the substitute teacher screening questions may be useful for the same hiring event.
The federal baseline
As of October 2026, from the federal regulations (not legal advice):
- Endorsements. A school bus is a commercial motor vehicle used to carry pre-primary, primary or secondary students to and from school or school events (49 CFR 383.5); buses designed for 16 or more people including the driver need a CDL. The S endorsement requires the P endorsement tests, a school bus knowledge test (loading and unloading, stop arms and mirrors, emergency exits and evacuation, railroad crossings) and a skills test in a school bus of the same group (383.123).
- Entry-level driver training. Anyone getting the P or S endorsement for the first time must complete training from a provider on FMCSA's Training Provider Registry (380.609). Drivers who held the endorsement before February 7, 2022 are exempt.
- Drug and alcohol testing. Part 382 applies to employers of CDL drivers, and the school bus and government exceptions do not apply to it (382.103), so districts and contractors run testing programs. The employer must run a full pre-employment Clearinghouse query with the driver's consent and query at least yearly (382.701). Since November 18, 2024, states must downgrade the CDL of a driver in prohibited status (383.73(q)).
- What does not apply. Most of the other federal motor carrier safety rules, including the Part 391 medical card rules, do not apply to home-to-school bus operations or to transportation by a state or local government (390.3T(f)). States fill that gap with their own medical, training and background rules.
The under-the-hood exemption and restricted licenses
Since 2022, FMCSA has let states waive the engine compartment part of the pre-trip inspection skills test for applicants seeking S and P endorsements, limited to intrastate driving (the K restriction) with a state "school bus only" restriction. The current exemption runs through November 28, 2026 (Federal Register, December 2, 2024), and a renewal request was published for comment in June 2026 with no decision published as of early October. New York, for example, says a CDL with its school-bus-only restriction cannot be renewed after the exemption expires (NY DMV). If a candidate's license carries these restrictions, find out what they mean in your state after November 2026.
States add the rest
| State example | Minimum age | Training and certification |
|---|---|---|
| California | Unlawful for anyone under 18 to drive a school bus transporting pupils (Vehicle Code 12516) | School bus driver certificate in addition to the CDL (Vehicle Code 12517); a course of at least 20 hours of classroom and 20 hours of behind-the-wheel training (Education Code 40082); Department of Justice background check before a temporary certificate; first aid exam |
| New York | At least 21 (8 NYCRR 156.3) | At least four hours of pre-service instruction, a basic course of at least 30 hours in the first year, and refresher training twice a year; fingerprints submitted within 10 days of hire (NYSED) |
Look up the state education department or DMV rules for the job location before your first screen, and ask the district who pays for training and how long certification usually takes.
Knockout questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 1. What class of CDL do you hold, with which endorsements and restrictions? | "Class B with P and S, air brake restriction removed, no K." Matches the license. | Says "school bus license" with no class or endorsements, or has not noticed a restriction on their card. |
| 2. (No S or P yet) Have you started entry-level training with a registered provider, or will you train with us? | Knows the provider, the test date, or accepts the district's program. | Expects to test without training. |
| 3. Do you meet [state]'s minimum age and hold, or can you get, the state school bus certificate? | Yes; for current drivers, the certificate expiry and last refresher date. | Certificate expired with no refresher. Do not ask for a date of birth. |
| 4. Routes run [6:15 to 8:45 a.m. and 2:15 to 4:30 p.m.], with occasional field trips. Can you work that split every school day? | Yes, and what they do in the midday gap. | Needs to leave by 3 p.m. on a route that ends at 4:30. |
| 5. The job requires fingerprinting, a drug and alcohol test, and your consent to a Clearinghouse query. Are you comfortable with that? | Yes. Has a Clearinghouse account or knows how to make one. | Refuses consent. Do not ask about past test results; the employer's query and records process handles it. |
Bus operation questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 6. What do you check on a school bus pre-trip that a truck driver would not? | Stop arm, crossing arm, eight-way lights, mirrors for the danger zone, emergency exits and roof hatches, first aid and body fluid kits, seats, wheelchair lift where fitted. | A truck pre-trip with no student equipment mentioned. |
| 7. Walk me through a stop where students cross in front of the bus. | Ambers on approach, full stop, reds and stop arm, checks traffic, counts students, signals them to cross in front where they can be seen, counts again before moving. | Lets students cross behind the bus, or pulls away before a final count. |
| 8. How do you cross railroad tracks with students on board? | Follows the state's procedure: stops before the tracks, quiets the bus, opens door and window, looks and listens both ways, crosses without shifting gears. | "I slow down and look." |
| 9. What do you do at the end of every route? | A walk to the back of the bus to check for sleeping or hidden children, then the child check system if fitted. | Relies on the alarm alone, or skips it when late. |
| 10. Fog rolls in on a rural route, or a stop has become unsafe because of construction. What do you do? | Slows, uses lights, calls dispatch, does not improvise a new stop without approval. | Moves stops on their own. |
Student and family questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 11. Two students start fighting while you are driving. What do you do? | Pulls over safely, uses voice and seat changes, calls dispatch or the school, writes a referral; does not physically intervene except to prevent harm under district policy. | Drives on yelling over their shoulder. |
| 12. Have you transported students with disabilities, or used wheelchair securements or child safety seats? | Describes four-point securement and occupant restraint, working with an aide, following the student's transport plan. | "They just sit up front." |
| 13. A student tells you something that makes you worry they are being harmed at home. What do you do? | Listens, does not promise secrecy, reports the same day through the district's procedure and the state's mandated reporter rules. | "Not my business." |
| 14. A parent confronts you at a stop about a seat assignment. What do you do? | Stays calm, keeps the bus secure, refers them to the transportation office, reports it. | Argues at the stop with students waiting. |
Record and fit questions
| Question | What a strong answer sounds like | Red flag |
|---|---|---|
| 15. Tell me about any accidents or moving violations in the last [period the employer's policy uses]. | A complete, specific list that the motor vehicle record will confirm. | Leaves something out that the MVR shows. |
| 16. Why school bus driving, and what would keep you here for several years? | The schedule, summers, students, benefits, a path to trainer or dispatcher. | Treats it as a stopgap until a freight job. |

Legal cautions
This section summarizes rules as of October 2026 and is not legal advice.
- Age. Ask whether the candidate meets the state's minimum age, never how old they are or when they plan to retire.
- Medical fitness. State rules may require a medical exam for school bus drivers. Ask whether the candidate holds or can get the required medical certification; do not ask about conditions or medications before an offer.
- Background checks. Fingerprint checks for school bus drivers are set by state law, while MVRs and other reports from background companies follow the Fair Credit Reporting Act; see the FCRA background check process. Follow the job location's fair chance rules for any criminal history questions beyond what state law requires.
- Everything else. Questions about family, religion, national origin or pregnancy are off limits; see illegal interview questions.
Questions people ask
What endorsements does a school bus driver need?
A CDL of the right class for the bus, usually Class B or Class C, with both the passenger (P) and school bus (S) endorsements. Under 49 CFR 383.123, the S endorsement requires passing the passenger endorsement tests, a school bus knowledge test and a skills test in a school bus of the same vehicle group.
Does a new school bus driver need entry-level driver training?
Yes, if they are getting the P or S endorsement for the first time. Under 49 CFR 380.609, they must complete training for that endorsement from a provider on FMCSA's Training Provider Registry. Drivers who already held the endorsement before February 7, 2022 are not required to.
Do school bus drivers have to be in the Drug and Alcohol Clearinghouse?
Their employer must query it. Part 382 applies to employers of CDL drivers, including school districts and other public bodies, and 49 CFR 382.701 requires a full pre-employment query, with the driver's consent, before the driver performs safety-sensitive functions, plus a query at least once a year.
How old do you have to be to drive a school bus?
It depends on the state. California law makes it unlawful for anyone under 18 to drive a school bus transporting pupils, while New York's education regulations require school bus drivers to be at least 21. Interstate CDL drivers must be at least 21 under federal rules. Ask whether the candidate meets the state minimum, not their age.
