1
Q
what can happen if you drive too fast around a curve?
A
if you take a curve too fast, your tires can lose traction and continue straight ahead, causing your vehicle to skid off the road, or your tires may retain traction, but your vehicle may roll over
2
Q
What is the rule about backing in a commercial vehicle?
A
Because your view of your surroundings is very limited, backing is always dangerous. Avoid it whenever possible. Parking in an area where you can pull out straight is a better alternative
3
Q
if you’re traveling at 55 mph on dry pavement, what is your reaction distance?

26
Securing devices called false bulkheads are often used to haul
because unconfined livestock can rock a CMV, securing devices called false bulkheads are often used to group the livestock together and prevent their movement. Even with the use of false bulkheads, however, livestock are known to lean on curves, which shifts the center of gravity and can cause your CMV to tip. Because of this, you have to turn especially slowly when transporting livestock
27
When transporting metal coils, the coils can be placed so that the “eyes” are
metal coils are very heavy and circular shaped, so they can roll, which makes them more likely to break loose and fall of a trailer. Because of this, the FMCSA has specific rules about how metal coils must be tied down on a trailer. The center of a metal coil is called the "eye." During transportation, metal coils may be placed on a trailer so that the eyes are vertical, crosswise, or lengthwise
