1Which endorsement authorizes a Minnesota CDL holder to drive a Type A, B, C, or D school bus while transporting students?
A.School Bus (S) endorsement
B.Tank Vehicle (N) endorsement
C.Doubles/Triples (T) endorsement
D.Hazardous Materials (H) endorsement
Explanation: Minnesota identifies School Bus as the S endorsement, and FMCSA requires specialized school-bus testing for it. The endorsement applies when transporting pupils in a school bus, not merely when driving any large vehicle.
2Under FMCSA rules, what must a School Bus endorsement applicant qualify for before receiving the S endorsement?
A.Passenger (P) endorsement knowledge and skills qualification
B.Hazardous Materials background check
C.Tank Vehicle endorsement qualification
D.Doubles/Triples endorsement qualification
Explanation: FMCSA requires a school bus endorsement applicant to qualify for the Passenger endorsement. The S endorsement adds school-bus-specific knowledge and a skills test in the proper school bus vehicle group.
3What minimum age does Minnesota DPS list for a school bus driver?
A.18 years old
B.16 years old with district approval
C.19 years old for all routes
D.21 years old for every route
Explanation: Minnesota DPS states that a school bus driver must be at least 18 years of age. Employers may set additional policies, but the DPS endorsement page lists 18 as the state minimum.
4What passing score does FMCSA require on CDL knowledge tests, including endorsement knowledge tests?
A.At least 80 percent correct
B.At least 60 percent correct
C.Exactly 70 percent correct
D.A score set by each school district
Explanation: FMCSA requires at least 80 percent correct on each CDL knowledge test. Minnesota CDL endorsement testing is administered under those federal standards.
5Minnesota DPS says endorsements are added to an existing CDL by passing the appropriate tests and applying for what license transaction?
A.A duplicate license
B.A recreational vehicle permit
C.A farm exemption card
D.A medical waiver only
Explanation: Minnesota DPS explains that adding endorsements to an existing CDL requires the appropriate tests and an application for a duplicate license. Medical documentation is important for CDL status, but it does not by itself add an endorsement.
6Which Minnesota CDL endorsements must be retested by written test at renewal according to Minnesota DPS?
A.Hazardous Materials and School Bus
B.Passenger and Tank Vehicle only
C.Doubles/Triples and Tank Vehicle only
D.All endorsements every renewal
Explanation: Minnesota DPS states that hazmat and school bus endorsements require retaking the written test at renewal. The page distinguishes those endorsements rather than saying every endorsement requires renewal retesting.
7For a new school bus or passenger endorsement in Minnesota, what kind of test does DPS say is required in an appropriate vehicle?
A.A road test
B.Only an online vision screening
C.Only a district ride-along
D.A motorcycle skills test
Explanation: Minnesota DPS states that adding school bus or passenger endorsements requires a road test in an appropriate vehicle. FMCSA also requires a school bus skills test in a school bus of the same vehicle group the applicant will drive.
8Which description best matches a Minnesota Type III school bus or Head Start bus?
A.A passenger car, station wagon, van, or bus with seating capacity of ten or fewer people including the driver and GVWR of 10,000 pounds or less
B.A bus with a GVWR over 21,500 pounds and maximum length of 45 feet
C.A stripped-chassis bus with the entrance door ahead of the front wheels
D.A cutaway bus required to carry more than ten persons
Explanation: Minnesota DPS describes Type III vehicles as passenger cars, station wagons, vans, and buses with seating capacity of ten or fewer including the driver and a GVWR of 10,000 pounds or less. Type III vehicles must not be outwardly equipped and identified as Type A, B, C, or D school buses.
9What is the danger zone around a school bus?
A.The area on all sides where children are most likely to be struck by the bus or another vehicle
B.Only the driver seat area inside the bus
C.Only the lane directly behind the bus
D.Only the railroad crossing area in front of the bus
Explanation: The Minnesota CDL manual defines the danger zone as the area on all sides of the school bus where children are most at risk of being hit. It includes areas in front, on both sides, behind, and especially blind areas around the bus.
10How far can the front danger zone extend from the front bumper of a school bus?
A.As much as 30 feet
B.Only 3 feet
C.Exactly 50 feet
D.One full traffic lane only
Explanation: The Minnesota CDL manual says the danger zone may extend as much as 30 feet from the front bumper. The first 10 feet in front of the bus is especially dangerous because the driver may not see a child there.

About the Minnesota CDL School Bus Test Exam

The Minnesota CDL School Bus Endorsement Test covers the specialized knowledge needed to operate a school bus safely under Minnesota DPS/DVS manual content and federal CDL rules.

Minnesota DPS also requires background check, physical qualification, and appropriate road testing for school bus endorsement applicants.

Assessment

Minnesota DVS-administered School Bus endorsement knowledge testing covering Minnesota CDL Manual Section 10 and FMCSA 49 CFR 383.123 topics, plus Passenger endorsement qualification and a school bus skills/road test in an appropriate same-group vehicle.

Minnesota CDL School Bus Test Study Tips from Top Performers

1Read the Minnesota DPS School Bus Endorsement page first so you understand age, background check, physical qualification, testing, cancellation, and school bus type context.
2Memorize the high-yield numbers: 80% passing score, 14-day CLP holding period, 15 to 50 feet before railroad tracks, 30-foot front danger zone, 10-foot side and rear danger zones, 100-foot evacuation area, and bus length plus 15 feet for railroad storage space.
3Practice loading and unloading as a sequence: approach, warn, stop, secure, check traffic, load or unload, count students, check mirrors, resolve missing students, and leave only when clear.
4Use mirror-purpose questions to separate flat mirrors, convex mirrors, crossover mirrors, and the inside overhead mirror.
5Treat railroad crossing scenarios as procedural questions: slow and signal, stop, secure, quiet the bus, open door and window, look and listen, cross in low gear, and never shift on the tracks.
6Before scheduling, confirm current DVS fees, ELDT status, CLP status, medical certification, background-check status, and the appropriate vehicle group for your road test.
