MS CDL School Bus: Suggested Study Strategy

1Learn the danger zone: up to 30 feet in front of the bumper (the first 10 feet are most dangerous), 10 feet on each side, and 10 feet behind; the left side is always dangerous because of passing cars.
2Know what each mirror should show: flat mirrors 200 feet or 4 bus lengths behind, convex mirrors the whole side and a lane on each side, and crossover mirrors the ground in front of the bumper to the service door.
3Memorize the stop sequence: amber lights at least 200 feet before the stop, right signal 100 to 300 feet before pulling over, stop 10 feet from students, then red lights and stop arm once traffic is a safe distance away.
4Know Mississippi's school bus speed limits under Miss. Code Ann. § 37-41-47: 45 mph on regular routes, 50 mph on other authorized trips, and 65 mph on interstates.
5Practice the railroad procedure under § 37-41-55: stop 15 to 50 feet from the nearest rail, open the service door and driver's window, look and listen, and never shift gears on the tracks.
6Always walk through the bus after a run to check for sleeping students and items left behind.

Frequently Asked Questions

What is the danger zone around a school bus?

The danger zone is the area immediately around the bus where children are in the most danger of being hit. It extends 10 feet all around the bus (front, sides, and rear), and up to 30 feet directly in front of the front bumper.

What are the school bus speed limits under Mississippi law?

Under Miss. Code Ann. § 37-41-47, the maximum speed for a school bus is 45 mph while transporting students on regular routes, 50 mph on other authorized school trips, and 65 mph on interstate highways (unless posted lower).

What is the railroad crossing procedure for school buses in Mississippi?

Under Miss. Code Ann. § 37-41-55, the driver must stop within 50 feet but not less than 15 feet from the nearest rail. While stopped, open the service door and driver's window and look and listen for trains, rail maintenance vehicles, and warning signals. Section 10.4.3 of the manual adds: turn off radios and noisy equipment, silence the passengers, and cross in a low gear without changing gears.

When should an emergency evacuation be conducted?

Section 10.3.1 of the Mississippi CDL Manual says evacuation is mandatory when the bus is on fire or there is a threat of fire, or when it is stalled on or next to a railroad crossing. It is also mandatory when the bus's position may change and increase the danger, when a collision is imminent, or when a hazardous materials spill requires a quick exit.

How far away from the bus should students assemble after an evacuation?

Section 10.3.2 says a safe place is at least 100 feet off the road in the direction of oncoming traffic. Lead students upwind if there is a fire, and upwind at least 300 feet if there is a risk from spilled hazardous materials.

Must a school bus driver hold both P and S endorsements in Mississippi?

Yes. The Mississippi Department of Education lists a Class A, B, or C CDL with P and S endorsements as a requirement, and federal rule 49 CFR 383.123 requires school bus endorsement applicants to pass the passenger endorsement knowledge and skills tests.

Are these practice questions the same as the official Mississippi test?

No. This is independent practice by OpenExamPrep built from the Mississippi CDL Manual and Mississippi law. It is a multiple-choice study aid, not a copy or simulation of the official DPS test, and it does not replace the skills test.
