Which type of hazard does not typically fall under physical features?

Distance to other vehicles is considered a behavioral or contextual factor rather than a physical feature of the roadway. While it is an important consideration for safe driving, it relates more to how the driver interacts with their environment and other road users, rather than the inherent characteristics of the roadway itself.

In contrast, road surface conditions, potholes in the road, and curves and bends in the road are all concrete aspects of the physical environment that can affect driving. These features can significantly impact vehicle handling and safety, making them crucial for emergency response drivers to assess and navigate effectively. Each of these physical features presents different hazards that can alter the dynamics of driving, but distance to other vehicles involves the positioning and behavior of both the driver and surrounding traffic, thus separating it from the category of physical features.
