When driving on rural roads, what can be restricted?

When driving on rural roads, the restriction of visibility and maneuverability is a significant concern. Rural roads often feature different characteristics compared to urban settings; they may have less frequent signage, narrower lanes, sharper curves, and areas with limited sight distance due to natural obstacles like trees or hills. These factors can hinder a driver's ability to see oncoming traffic, pedestrians, and potential hazards well in advance, thereby increasing the risk of accidents.

Additionally, the maneuverability on rural roads can be restricted due to factors such as the road's width, the presence of gravel or dirt, and lack of proper road maintenance, which may affect how smoothly a vehicle can navigate. This makes it critical for drivers to be extra cautious and aware of their surroundings when traveling in these areas. While the other options may also have implications for rural driving, they do not encapsulate the primary concern regarding the unique challenges presented by the environment of rural roads as directly as visibility and maneuverability do.
