Before you start driving in winter, what does the manual say about snow and ice on your vehicle?
-
A.
Drive slowly until the vehicle warms up enough to melt it.
-
B.
Remove it all from the vehicle and clear all windows before driving. Correct
-
C.
Leave the snow if it is under one inch thick.
-
D.
Remove only what covers the front windshield and side mirrors.
The answer is "Remove it all from the vehicle and clear all windows before driving."
The manual requires you to remove all snow and ice from the vehicle and clear every window before the windshield is defrosted and you begin driving. Choice D follows the running-late habit of scraping only what the driver looks through, which the manual does not sanction.
The traps in the wrong answers
A. Drive slowly until the vehicle warms up enough to melt it.
The manual does not allow driving to warm the vehicle as a substitute for clearing snow. This answer uses the defroster warm-up reflex as if it took the place of scraping.
C. Leave the snow if it is under one inch thick.
The manual sets no depth threshold that lets a driver skip the clearing step. This answer invents a thickness cutoff the manual never sets.
D. Remove only what covers the front windshield and side mirrors.
Clearing only the windshield and mirrors leaves the roof and rear window loaded with snow that can slide onto the driver's view or another vehicle. This answer comes from the habit of clearing only what you look through when running late.
