The Correct Answer and Explanation is:
Here are the correct answers and a detailed explanation for each question.
Question 3: True
Question 4: False
Explanation
Question 3: Visual References
The correct answer is True. Visual references are a fundamental and indispensable part of safe driving. These are specific points on the driver’s own vehicle, such as the corners of the hood, the side mirrors, or even a spot on the dashboard, that are used to judge the vehicle’s position in relation to external objects like lane lines, curbs, and other cars.
For lane positioning, a driver learns to align a certain part of their car with the lane markings to stay centered. For example, they might keep the right lane line aligned with the center of the hood. These reference points are also crucial for maneuvers like turning and parking. When preparing to make a right turn, a driver might use the moment their side mirror passes the curb line as the signal to begin turning the wheel. This prevents them from turning too early and hitting the curb or turning too late and swinging into an adjacent lane. Without these established visual cues, a driver would have a much harder time accurately judging the space around their vehicle, leading to poor lane discipline and an increased risk of collision.
Question 4: Car Pillar Terminology
The correct answer is False. The statement misidentifies the car pillar in question. Automotive body pillars are named alphabetically from the front of the vehicle to the back.
- A-pillar: The pillars on either side of the windshield.
- B-pillar: The central pillar on a four-door car, located between the front and rear doors.
- C-pillar: The rearmost pillar of a typical sedan or coupe, which supports the roof and frames the rear window.
The question describes the pillar connecting the rear window to the rear door frame, which is correctly identified as the C-pillar. The D-pillar is a term reserved for larger vehicles like station wagons, minivans, and SUVs. In these vehicles, the D-pillar is the final support at the very back, located behind a third row of windows or the cargo area’s side glass. A standard four door car does not have a D-pillar. Therefore, the statement is incorrect.
