Not quite. The answer is 3 seconds
The formula for following distance is one second for every ten feet of vehicle length, plus an extra second if you are traveling over 40 mph.

7Question 7 of 20
When is it best to wear your seat belt?
Not quite. The answer is Whenever you're driving

Also remind disembarking passengers to take all their carry-on luggage and other personal effects with them as they get off the bus.
9Question 9 of 20
Buses may carry
Not quite. The answer is small-arms ammunition.
Buses may carry small-arms ammunition marked "Limited Quantity" (relatively small quantity of hazmat; formerly "ORM-D"), emergency hospital supplies, and drugs. Buses may carry small amounts of some other hazardous materials if the shipper cannot send them any other way. Buses may not carry more than 100 pounds of any class or more than 500 pounds total.
10Question 10 of 20

11Question 11 of 20
Should a bus driver who is feeling sleepy start a conversation with a passenger?
Not quite. The answer is No, because it may distract the bus driver from driving.

12Question 12 of 20
How many temporary folding aisle seats are permitted in a bus that is NOT carrying farm workers?
Not quite. The answer is Zero
Federal regulations require all seats to be securely fastened to the bus. Temporary folding seats are not permitted on a bus unless it's carrying agricultural workers on short trips. [49 CFR 393.91],
Source: 29 CFR 500.105

Not quite. The answer is The emergency window
Emergency exit windows and doors must be closed while the bus is being driven.
15Question 15 of 20
When you're driving a bus, what does "rock and roll" mean?
Not quite. The answer is Swaying your body to see around obstructions
A vehicle's pillars help hold up the roof and maintain structural integrity of the vehicle. The pillars on a bus can be quite wide. Together with the side mirrors, they create obstructions to your vision that can be at least a foot wide, resulting in blind spots. A pedestrian (or even a small vehicle) can seem to disappear completely behind a pillar, which can be especially dangerous if you turn into the pedestrian's path. For this reason, your bus driving instructor may teach you to "rock and roll" when turning your bus: sway your body forward and backward and from side to side to help you see around the pillars and mirrors.
16Question 16 of 20
Which of the following items is NOT federally required emergency equipment in a CMV?
Not quite. The answer is A spare jacket
Federal regulations require CMVs to carry emergency warning devices, such as reflective triangles, and a properly rated fire extinguisher. A spare jacket may be useful in cold weather, but it is not federally required emergency equipment. Spare electrical fuses are also no longer federally required under current FMCSA regulations.
Source: 49 CFR 393.95
17Question 17 of 20
Before you start to drive, you must inspect all of the following EXCEPT
Not quite. The answer is the AM/FM radio.
Before you start to drive, you must check all the critical systems such as steering, brakes, tires, and emergency equipment to be sure they work properly. For the passengers' safety, you must also check such interior items as seats, handholds, railings, signaling devices, and emergency exits. FM or DVD music is nice, but you can safely drive your passengers to their destinations without it.
18Question 18 of 20
Your bus is disabled. With riders aboard, the bus may be towed or pushed to a safe place
Not quite. The answer is only if getting off the bus would be more risky for the riders.
Passengers should not be aboard a bus while it is being towed unless it would be more dangerous for them to exit the vehicle. Passengers can remain aboard the bus only until it is towed or pushed to the nearest safe location.
19Question 19 of 20
You are driving at night, and you need to dim your headlights for traffic. You should
Not quite. The answer is slow down.
You should always be able to stop within the distance you can see ahead. Your low-beam headlights let you see only about 250 feet ahead. At 55 mph, your vehicle will travel 250 feet in just 3.1 seconds – not enough time to notice and safely avoid a hazard that's within 250 feet of you. At 30 mph, your vehicle will travel 250 feet in 5.7 seconds.
20Question 20 of 20
When you discharge an unruly passenger, you must choose a place that is
Not quite. The answer is as safe as possible, or the next stop.
