Final answer:
Vehicles, pedestrians, and other objects in motion near a driver are indeed potential hazards; recognizing them is crucial for road safety. Whether it is safe to cross a road with an oncoming car 28 meters away depends on various factors, and caution is always recommended.
Step-by-step explanation:
Yes, vehicles, pedestrians, or other objects in motion in a motorist's immediate proximity are potential hazards. It is true that these can pose a threat to the safety of the motorist as well as others in the vicinity. The reason why this is important is that recognizing potential hazards is essential for safe driving practices and for the prevention of accidents.
Regarding the specific situation of a car being 28 meters away, whether it is safe to walk across the road depends on various factors such as the speed of the oncoming car, the road conditions, and the pedestrian’s speed. Generally, it is advised to be cautious and wait until the car passes unless you can clearly gauge that you have enough time to cross safely without causing a hazard.
Understanding the motion of objects, such as whether an object is moving in a positive or negative direction, or if it's moving at constant speed or at rest, is critical for motorists to avoid creating or being involved in hazardous situations on the road.
