1. When the roads are slippery, you should make turns as gentle as possible.
2. The heavier a vehicle or the faster it is moving, the more heat the brakes have to
absorb to stop it.
3. Truck escape ramps help avoid damage to vehicles.
4. You are starting your vehicle in motion from a stop. As you apply power to the drive
wheels, they start to spin. You should take your foot off the accelerator.
5. The distance that you should look ahead of your vehicle while driving amounts to
about 1/4 mile at highway speed.
6. Defensive driving suggests that you lightly tap your horn, drive carefully to avoid a
crash, and assume the other driver does not see you when you pass a vehicle.
7. When you downshift for a curve, you should do so before you enter you enter the
8. Turning too sharply, not enough weight on the front axle, and over acceleration can
cause a vehicle to skid.

name of a hazard class on the shipping paper; a four-inch, diamond-shaped hazardous
materials label on the container; a hazardous materials placard on the vehicle.
12. To avoid a crash, you had to drive onto the right shoulder. You are now driving at 40
MPH on the shoulder. If the shoulder is clear, stay on it until your vehicle has come to a
stop. Then move back onto the pavement when it is safe.
13. You can use water to put out a tire fire.
14. You should use your mirrors to check: the condition of your tires, where the rear of
your vehicle is while you make turns, traffic gaps when merging.
15. These statements are true about speed management: on a wet road, you should reduce
your speed by about one-third; on packed snow, you should reduce your speed by at least
one-half; when the road is slippery, it will take longer to stop and it will be harder to turn
without skidding.
16. Your vehicle is in a traffic emergency and may collide with another vehicle if you do
not take action. You should remember that you can almost always turn to miss an
obstacle more quickly then you can stop.
17. You should inspect your tires every two hours or every 100 miles when driving in
very hot weather.
18. If the wheels are skidding, you cannot control the vehicle.

23. Keep your speed slow enough that you can stop within the range of your headlights.
24. Winds are especially a problem when coming out of tunnels.
25. To help you stay alert while driving; you should take short breaks before you are

38. Turning the wheel back in the other direction after steering to avoid a traffic
emergency is countersteering.
39. You are driving a vehicle that could safely be driven at 55 MPH on an open road.

46. The center of gravity of a load can make a vehicle more likely to tip over on curves if
it is high.
47. If a hill or curve keeps drivers behind you from seeing the vehicle within 500 feet, the
rear reflective triangle should be moved back down the road to give adequate warning.
48. You are checking your brakes and suspension system for a pre-trip inspection. Brake
shoes should not have oil, grease, or brake fluid on them. Brake pads should not have
brake fluid on them. One missing leaf in a leaf spring can be dangerous.

vehicle has slowed down.
59. Heavy vehicles need larger gaps in traffic than cars.
60. Sleep is the only thing that can overcome fatigue.
61. There are “blind spots” that your mirror cannot show you.
You are checking your steering and exhaust systems in a pre-trip inspection. You find
steering wheel play of more than 10 degrees; leaks in the exhaust system; and a small
leak of power steering fluid. All of which should be fixed before the vehicle is driven.
62. Your vehicle has hydraulic brakes. While traveling on a level road, you press the

the vehicle until the clutch engages.
67. Don’t turn any more than needed to clear what is in your way when steering to avoid
a crash.
68. You are checking your wheels and rims for a pre-trip inspection. Rust around wheel
nuts may mean that they are loose.
69. You do not have a hazardous material Endorsement on your Commercial Driver’s
License. You are asked to deliver hazardous materials in a placarded vehicle. You
should refuse to haul the load.

71. If you need to leave the road in a traffic emergency, you should avoid braking until
your speed has dropped to about 20 MPH.
72. You should stop driving whenever you become sleepy.
73. You should avoid driving through deep puddles or flowing water. But if you must,
gently putting on the brakes while driving through the water can help to keep your brakes
74. Escape ramps are used to stop runaway vehicles; designed to prevent injury to drivers
and passengers; and designed to prevent damage to vehicles.
75. Avoiding high-speed driving, making sure the engine has the right amount of oil, and
proper v-belt tightness will help keep an engine cool in hot weather.
76. When driving at night, you should adjust your speed to keep your stopping distance
within your sight distance.
77. Cargo securement, wiper blades, and whether all vehicle lights are working and are
clean should be checked in a pre-trip inspection.

overloading; other highway users to hit or be hit by loose cargo, and injury to the driver
during a quick stop or crash.
91. If you must drive on a slippery road, slow down gradually.
92. You are driving a vehicle that makes wide turns. You are driving on a two-lane, twoway street and you want to turn left onto another two-lane, two-way street. You should
turn into the left lane of the new street and then move to the right.
