CDL School Bus 模拟考试

背书代码：S

The School Bus endorsement (S) authorizes you to drive a school bus carrying students. This is one of the most regulated CDL endorsements due to the safety of child passengers. In addition to the knowledge test, most states require a thorough background check, and many require a separate skills test in a school bus. School bus drivers must also hold a Passenger (P) endorsement.

Questions cover student loading and unloading procedures, mirror use and adjustment, railroad crossing procedures specific to school buses, emergency evacuation, use of warning lights and stop arm, student behavior management during transport, danger zones around the bus, and pre-trip inspection procedures. Many questions focus on the loading zone -the most dangerous area for students.

School Bus 常见问题

Do I need both the P and S endorsements to drive a school bus?

Yes. Federal regulations require both a Passenger (P) endorsement and a School Bus (S) endorsement to operate a school bus. The P endorsement covers general passenger transport safety, while the S endorsement covers school bus-specific rules. You must pass both knowledge tests.

What is the most dangerous area around a school bus?

The danger zone extends 10 feet from the front bumper, 10 feet from each side, and the area directly behind the bus. The most dangerous spot is directly in front of the bus where small children can be hidden from the driver's view. Drivers must account for all students in the danger zone before moving the bus.

What are the school bus railroad crossing rules?

School buses must stop at all railroad crossings, even if no train is visible. The driver must stop within 15 to 50 feet of the nearest rail, open the driver-side window and the service door, look both directions, and listen for trains before proceeding. The bus must not shift gears while crossing the tracks.

How do school bus warning lights work?

School buses use a two-stage warning system. Amber warning lights activate approximately 100 to 300 feet before the stop to alert traffic that the bus is preparing to stop. Red warning lights and the stop arm activate when the bus is fully stopped and students are loading or unloading. Traffic in both directions must stop when the red lights are flashing (unless separated by a divided highway).

What background check is required for school bus drivers?

School bus drivers must pass a federal and state criminal background check. Many states require fingerprinting as part of this process. Convictions for certain offenses -including DUI, drug crimes, violent crimes, and sex offenses -will disqualify you. Most states also require a clean driving record and periodic re-checks throughout employment.
