Which of the following is NOT a condition under which parking is allowed on a public road?

Parking near a fire hydrant is not allowed because it poses a significant risk to public safety. Fire hydrants are critical for emergency response, especially during fires, and maintaining a clear access path to them is essential. If a vehicle is parked too close to a fire hydrant, it can impede firefighters’ ability to quickly connect hoses and access water, which can jeopardize lives and property.

In contrast, the other conditions listed—visibility of the vehicle for at least 200 feet, not obstructing traffic, and parking away from curves—are all designed to enhance safety and ensure traffic flow on public roads. These rules help prevent accidents and ensure that vehicles are not left in a way that could hinder the movement of other vehicles or pedestrians. Therefore, option C accurately reflects a condition under which parking is not allowed on a public road.
