Sample CDL School Bus Endorsement practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Weight and Capacity
A school bus with a Gross Vehicle Weight Rating (GVWR) of 30,000 lbs is carrying 30 passengers, each weighing an average of 150 lbs. The bus itself weighs 22,000 lbs. What is the total weight of the bus and its passengers when fully loaded, and what is the remaining weight capacity?
- A.Total weight: 26,500 lbs; Remaining capacity: 8,000 lbs
- B.Total weight: 25,500 lbs; Remaining capacity: 4,500 lbs
- C.Total weight: 26,500 lbs; Remaining capacity: 3,500 lbs(Correct)
- D.Total weight: 22,000 lbs; Remaining capacity: 8,000 lbs
Explanation
The total weight is the bus weight plus the passenger weight. Passenger weight = 30 passengers * 150 lbs/passenger = 4,500 lbs. Total weight = 22,000 lbs (bus) + 4,500 lbs (passengers) = 26,500 lbs. Remaining capacity = 30,000 lbs (GVWR) - 26,500 lbs (total weight) = 3,500 lbs.
- Question 2Railroad Crossings
You are approaching a railroad crossing marked with a standard 8-crossbuck sign. Which of the following actions is MOST critical for ensuring safety?
- A.Honk the horn to alert any potential pedestrians near the tracks.
- B.Actively scan for any train traffic and listen for audible warnings, preparing to stop.(Correct)
- C.Slow down to a speed no faster than 15 mph and be prepared to stop.
- D.Turn on hazard lights to warn other vehicles of your approach.
Explanation
While slowing down (option B) is a good practice, the most critical action is actively scanning and listening for trains. Railroad crossings are inherently dangerous, and vigilance for approaching trains is paramount to avoid a collision. Hazard lights (option D) are not standard procedure for railroad crossings, and honking (option C) is not the primary safety measure.
- Question 3Signaling and Stopping Procedures
A school bus is equipped with a flashing red light system. If the school bus stops on a two-lane road with no median strip and a posted speed limit of 45 mph, how far in advance of the stop should the driver activate the flashing red lights and stop arm?
- A.At least 300 feet(Correct)
- B.At least 100 feet
- C.At least 200 feet
- D.At least 500 feet
Explanation
According to typical regulations for school bus safety, flashing red lights and the stop arm should be activated at least 300 feet before the bus stops to pick up or drop off passengers, allowing ample time for approaching traffic to react and prepare to stop.
