Ice tends to form first on bridges and overpasses because cold air circulates above and below the structures causing the temperature to drop more rapidly than on normal roads.
Correct Answer
A. True
Explanation
Ice tends to form first on bridges and overpasses because cold air circulates above and below the structures causing the temperature to drop more rapidly than on normal roads. This is because bridges and overpasses are elevated structures, allowing cold air to circulate around them, whereas normal roads are closer to the ground and have more insulation from the surrounding air. As a result, bridges and overpasses cool down faster, causing any moisture in the air to freeze and form ice more quickly than on normal roads.
34.
Any moisture on the road surface of a bridge or overpass will freeze later and will be slushier than elsewhere on the road.
Correct Answer
B. False
Explanation
Moisture on the road surface of a bridge or overpass will not necessarily freeze later or be slushier than elsewhere on the road. This statement is false because the freezing and slushiness of the road surface depend on various factors such as temperature, humidity, and the condition of the road. While bridges and overpasses may freeze more quickly due to their elevated position, it is not always the case that they will be slushier than other areas of the road.
35.
During snowy and icy weather, extreme caution and a reduction in speed should be used while traveling over bridges and overpasses.
Correct Answer
A. True
Explanation
During snowy and icy weather, bridges and overpasses can become more slippery and dangerous than regular roads.
