Correct Answer: make sure there is no ice on the radiator shutters.
the question is asking what measures should be taken before driving in cold weather conditions. it provides several statements for consideration. the first statement suggests checking the roof for ice. this is necessary because ice on the roof can slide down and obstruct the driver's view or even cause accidents by sliding onto the road and creating a hazard for other drivers.
the second statement mentions ensuring there is no ice on the radiator shutters. this is crucial as the radiator must be able to cool the engine effectively. if the shutters are blocked by ice, it could cause the engine to overheat.
the third statement emphasizes the dangers of driving in cold weather and the importance of taking precautions. it is generally recommended to clear all ice and snow from the vehicle, including lights, reflectors, windows, mirrors, handholds, steps, and decks. it's important to ensure these parts are clear for visibility and safety.
additionally, the exhaust system should be checked for loose parts or signs of leaks, which could be exacerbated by the cold temperatures and could lead to dangerous situations like carbon monoxide poisoning if not addressed.
the fourth statement incorrectly suggests that ice should only be removed from the front and back windows. this is not accurate. all windows should be cleared of ice to ensure maximum visibility while driving.
the fifth and final statement suggests making sure the vehicle runs for at least 10 minutes prior to driving. this is a commonly recommended practice as it allows the engine to warm up and reach its optimal operating temperature, which can improve vehicle performance and reduce wear and tear on the engine in cold weather.
in conclusion, the true statements before driving in cold weather are checking the roof for ice, ensuring there is no ice on the radiator shutters, clearing all ice and snow from the vehicle, checking the exhaust system, and running the vehicle for at least 10 minutes before driving.
