CDL - Class C Drivers License

Correct!
A. steer right.

Explanation:
Stopping is not always the safest thing to do in an emergency. When you don't have enough room to stop, you may have to steer away from what's ahead. Remember, you can almost always turn to miss an obstacle more quickly than you can stop. If an oncoming driver has drifted into your lane, a move to your right is best. If that driver realizes what has happened, the natural response will be to return to his or her own lane. If something is blocking your path, the best direction to steer will depend on the situation. If you have been using your mirrors, you'll know which lane is empty and can be safely used. If the shoulder is clear, going right may be best. No one is likely to be driving on the shoulder but someone may be passing you on the left. You will know if you have been using your mirrors. If you are blocked on both sides, a move to the right may be best. At least you won't force anyone into an opposing traffic lane and a possible head-on collision.

2.17.1: Driving Emergencies - Steering to Avoid a Crash

Correct!
B. hazard.

Explanation:
A hazard is any road condition or other road user (driver, bicyclist, pedestrian) that is a possible danger. For example, a car in front of you is headed toward the freeway exit, but the brake lights come on and the driver begins braking hard. This could mean that the driver is uncertain about taking the offramp. The vehicle might suddenly return to the highway. This car is a hazard. If the driver of the car cuts in front of you, it is no longer just a hazard; it is an emergency. You will have more time to act if you see hazards before they become emergencies. In this example, you might make a lane change or slow down to prevent a crash if the car suddenly cuts in front of you. Seeing this hazard gives you time to check your mirrors and signal a lane change. Being prepared reduces the danger. A driver who did not see the hazard until the slow car pulled back on the highway in front of him or her would have to do something very suddenly. Sudden braking or a quick lane change is much more likely to lead to a crash.

Correct!
B. orange

Explanation:
Hazardous materials are products that pose a risk to health, safety, and property during transportation. Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle that identify the hazard class of the cargo. A placarded vehicle must have at least four identical placards. They are put on the front, rear, and both sides. Placards must be readable from all four directions. They are at least 10 3/4 inches square, turned upright on a point, in a diamond shape. Cargo tanks and other bulk packaging display the identification number of their contents on placards or orange panels.

Correct!
B. 4.5

Explanation:
There are three things that add up to total stopping distance: perception distance, reaction distance, and braking distance. Braking distance is the distance it takes to stop once the brakes are put on. At 55 mph on dry pavement with good brakes it can take a heavy vehicle about 390 feet to stop, which takes about 4 1/2 seconds.

2.6.1: Controlling Speed - Stopping Distance

Correct!
A. instructions about how to load, transport, and unload bulk tanks.

Explanation:
You must follow the many rules about transporting hazardous materials. The intent of the rules is to contain the product, communicate the risk, and ensure safe drivers and equipment. Many hazardous products can injure or kill on contact. To protect drivers and others from contact, the rules tell shippers how to package safely. Similar rules tell drivers how to load, transport, and unload bulk tanks. These are containment rules. The shipper uses a shipping paper and diamond shaped hazard labels to warn dockworkers and drivers of the risk. After an accident or hazardous material spill or leak, you may be injured and unable to communicate the hazards of the materials you are transporting. Firefighters and police can prevent or reduce the amount of damage or injury at the scene if they know what hazardous materials are being carried. Your life, and the lives of others, may depend on quickly locating the hazardous materials shipping papers. For that reason, you must tab shipping papers related to hazardous materials or keep them on top of other shipping papers. You must also keep shipping papers in a pouch on the driver's door, or in clear view within reach while driving, or on the driver's seat when out of the vehicle.
