Final answer:
To safely park near a curb, the ideal distance is 12 inches. When crossing a street, you should be able to walk at least 4 meters beyond the width of a car for safety.
Step-by-step explanation:
When parking near a curb, the recommended distance from the curb you should park is 12 inches (Option B). It's essential to follow this guideline to ensure safety and adherence to traffic laws, making sure that your vehicle does not obstruct the flow of traffic or pedestrians.
Regarding the safety aspect of crossing the street, in towns and cities with a speed limit of 60 km.hr⁻¹, where the average car's width is 2 meters, a safe rule is to ensure you can walk at least 4 meters beyond the car's width before the vehicle reaches you. This provides adequate space to cross safely.
