What types of locations on the autobahn are particularly prone to ice hazards?

Answer: C — Both answers are correct

The correct answer is that both bridges and curves on the autobahn are particularly prone to ice hazards. This is due to the fact that bridges are often exposed to colder air on both the top and bottom, which can lead to faster freezing of moisture compared to roadways that are supported by the ground. Consequently, bridges may freeze over even when the rest of the road is clear. Curves, on the other hand, can accumulate ice due to the centrifugal forces acting on vehicles, which can cause moisture to gather and freeze more readily in those areas. The combination of these factors makes both bridges and curves critical points for drivers to be cautious of potential ice hazards, particularly during winter months or in conditions where temperatures fluctuate around the freezing point. Other locations such as stretches leading through urban areas may not be as consistently exposed to ice conditions, as traffic and urban infrastructure tend to keep those areas warmer than more exposed parts of the road network.
