Final answer:
The conditions where providing protection would be required include foggy weather, snowfall, near a crossing, near a curve, and during rain. These conditions can pose risks to drivers and increase the likelihood of accidents.
Step-by-step explanation:
List of conditions where providing protection would be required:
- Foggy weather
- During snowfall
- Near a crossing
- Near a curve
- During rain
These conditions can pose risks to drivers as they can limit visibility and increase the likelihood of accidents. For example, in foggy weather or during rain, it may be harder for drivers to see other vehicles, pedestrians, or road signs, potentially leading to collisions. Similarly, being near a crossing or a curve can increase the chances of accidents due to decreased visibility.
