Final answer:
Before entering a vehicle, checking around for obstacles or people is crucial for safety. Whether it's safe to cross a road with an oncoming car 28 meters away depends on speed and conditions but is generally risky without sufficient information.
Step-by-step explanation:
Before getting into a vehicle, a motorist should look behind and in front of it primarily to avoid accidentally running over obstacles or people. This is important as it ensures the safety of the motorist and others around the vehicle. It helps in identifying any potential hazards such as children playing, pets, toys, or other objects that might be in the path of the vehicle once it starts moving. In addition, checking the surroundings can also reveal if there has been any vandalism or damage to the vehicle that could pose a risk while driving.
Addressing part (f) of the student's question, whether it is safe to walk across the road if you see a car driving toward you and it is 28 meters away, depends on several factors such as the car's speed, the road conditions, visibility, and your walking speed. Without knowing the speed of the oncoming vehicle, it is not possible to give a definitive answer. However, it is generally safer to wait until the car has passed than to assume you have enough time to cross safely.
