Chapter 16 ws Questions and Answers

Chapter 16 ws Questions and Answers Explain why knowing the difference between a fully-controlled access highway and a non-controlled access helps to make you a low-risk driver. (p. 321; 2 pts) Controlled access - vehicles can enter and leave only at designed intersections Non-controlled access - expressways could have traffic lights, intersections, and driveways where traffic is able to enter or leave the expressway Explain the differences between interstate, U.S., and state highways, and their numbering systems. (pps. 321 & 322; 3 pts) Interstate highway - Controlled access - vehicles can enter and leave only at designed intersections. The interstate highway sign is a red, whtie, and blue shield. U.S. highway - Most of the state highways and U.S. highways have non-controlled access, which allowed drivers to to enter and leave the highway from any point. There are intersections with traffic controls to separate crossing traffic, which makes traveling slower and more dangerous than being on controlled - access freeway. State Highway - The state highway system is a network of highways existing within the boundaries of a state. Many of these highways are narrow two - lane roadways in rural areas. Numbering system (Figure 2 on p.321) - The even numbered routes run east and west with the lower numbered routes beginning in the south. The odd numbered routes go north and south with the lowest numbers beginning on the west coast. Explain how each type of interchange helps to keep traffic moving. (p.321; 2 pts) Cloverleaf - is a two-level interchange in which all turns are handled by slip roads Diamond - A diamond interchange is a common type of road junction, used where a controlled-access highway crosses a minor road Describe the actions that help the driver to merge smoothly while in the acceleration lane. (p. 327; 2 pts) If entrances have very short acceleration lanes, slow down to provide the best opportunity to merge. Otherwise you wll be forced to reduce your sped or come to a stop while on the acceleration lane, which creates a highly dangerous situation. Describe a situation on an entrance ramp that might prevent the driver from merging safely. (p. 327; 1 pt) a closed front zone or merging from the left entrance ramp Why is the correct speed so important on the entrance ramp? (p. 325; 1 pt) Driving more slowly provides time to evaluate zone conditions and to select a gap in the traffic flow, which allows you to slip into the gap or hole without causing drivers behind you to brake. Why is it so important to look for an opening in traffic? (pps. 325 & 326; 1 pt) you will be able to predict between which vehicles you should merge so your not panicking at the last second How is using the IPDE System on interstate highways different from using it on other roadways? (p 329; 2 pts) Highway driving makes using the IPDE process and Zone control easier than driving on two - lane roads because there are more opportunities to search farther ahead and there are fewer variations of highway designs to change your intended path of travel. Why is it so important for a driver to identify reversible lanes? (p. 330; 1 pt) Traffic lanes where traffic can travel in either direction depending on certain conditions are called reversible lanes. While reversible lanes are good for opening more lanes to traffic, they can also be deadly. Many head on collisions. How does using the four (4) or more second rule on highways, when following a vehicle, help you to be a low-risk driver? (p. 331; 1 pt) you want 4 seconds or more between you and the other vehicle on a highway because if the car in front of you stops, slows down, or their car breaks down you have time to switch lanes or stop Explain what to do if your exit lane has an overflow. (p. 335; 1 pt) you should drive past and use the next exit Explain how you apply the IPDE Process when you exit an interstate. (p. 335; 1 pt) Identify the green guide signs that show the distance to your exit. Identify any potential wheeze pattern before you reach teh exit. Identify closed and open zones. Predict actions of other drivers who might be using the same exit. Decide on the best speed and lane position before getting in the acceleration lane. Execute your maneuver smoothly and blend with slower traffic. Why should a driver look one-half mile ahead before exiting an interstate highway? (p. 336; 1 pt) to avoid last second decisions and sudden moves Explain why it is so dangerous to drive on a highway for extended periods of time without a break. (p. 338; 1 pt) Staying on a highway can be a problem when you travel a long distances att a steady speed or are tired. You can be lulled into an inattentive drowsy state called highway hypnosis. Explain why it is so important to check your speed at exit ramps. (pps. 338 & 339; 1 pt) because you always need to slow down on exit ramps
