Which of the following regarding a collision is/are true? a. If you triple your speed your force of impact will be three times greater b. Speed has little effect on impact forces c. If you double your speed, the energy dissipated in a crash is four times greater d. If you double your speed, the energy dissipated in a crash is two times greater - Answer-C If you are able to reduce your speed by half before crashing into a concrete post, the kinetic energy experienced in the crash will be reduced by four times. a. True b. False - Answer-A While driving you see a dangerous situation ahead and must take immediate action. Which of the following is/are correct? a. It is better to steer right instead of toward oncoming traffic to prevent a crash b. If you crash into the side of another vehicle, hitting that vehicle behind the rear wheels will increase the survivability of the occupants of both vehicles. c. Hitting a row of bushes is better than hitting a tree, post or solid object d. All of the above - Answer-D When people are involved in vehicle crashes, three collisions occur. Which of the following is/are true? a. The second collision is the human collision that occurs when the occupants of a vehicle come to a stop against the interior of the vehicle they were traveling in b. The third collision occurs when the internal organs of the occupant strike the skeletal system and other organs in the stopped body of the occupant. c. Seat belts and air bags help reduce the effects of the second and third collisions by preventing belted occupants from striking the interior of the vehicle as the passenger compartment comes to a stop after the initial impact, called the first collision d. All of the above - Answer-D Which of the following is/are true?a. Vehicles are designed to dissipate the energy associated with collisions and to protect the passenger compartment b. When a collision occurs, the front and rear structures of vehicles are designed to deform and buckle in a carefully designed and controlled manner to dissipate the energy associated with the crash c. Vehicle design features are more effective if speed is reduced, drivers take actions to reduce the impact associated with collisions, and if vehicle occupants are wearing seatbelts d. All of the above - Answer-D Drivers exercise judgment and skill when they are behind the wheel. Of these two capabilities, driving skill is by far the most important. a. True b. False - Answer-B When driving, you should attempt to scan 20-30 seconds ahead of your vehicle. If you are traveling at highway speeds, 50, 60, or 70 miles per hour, you will travel about one mile per minute. Therefore, you should be scanning about how far ahead: a. About 100 feet b. About 500 feet c. About 1/2 mile d. About 1 mile - Answer-C to properly scan 20-30 seconds ahead, you should scan this entire distance ahead of your vehicle. As you scan ahead, you should: a. Identify situations, vehicles, or objects that could cause a problem by the time they reach the midpoint of your scanning distance about 15 seconds ahead of your vehicle. b. Be particularly alert for immediate hazards that may present themselves in the area that is 2-5 seconds ahead of your vehicle. c. Delay taking defensive actions such as slowing or changing lanes until the situation, vehicle or object ahead is 2-5 seconds ahead of your vehicle. d. Both a. and b. above - Answer-D Proper scanning of the roadway provides time for the driver to adjust speed and path to avoid dangerous situations. Which of the following is/are true? a. To accomplish proper scanning, look 20 to 30 seconds ahead and to the sides and rear to identify potentially dangerous situationsb. Drivers should adopt a mindset that says the driver approaching the intersection from the left or right may not stop at the traffic signal c. If scanning ahead identifies a potential danger, you must take action to avoid a crash d. All of the above - Answer-D The SIPDE process includes the following steps: Squinting, Influencing, Protecting, Driving, and Escaping. a. True b. False - Answer-B, SEARCH IDENTIFY PREDICT DECIDE EXECUTE
