Final answer:
Drivers must always stop before the sidewalk when exiting a side street or alley to ensure pedestrian safety. The color of a car does not affect driving speed, and crossing roads safely depends on multiple factors, including visibility and vehicle speed.
Step-by-step explanation:
The question pertains to traffic laws and safe driving practices. According to traffic regulations, the correct answer is A) Yes, always. A driver emerging from a side street or alley is required to stop before crossing over the sidewalk. This ensures the safety of pedestrians who may be using the sidewalk, as it gives the driver an opportunity to check for any incoming foot traffic, thus preventing potential accidents. It's important to be aware of the speed limit and surroundings, whether it is safe to cross the road outside of a pedestrian crossing, and that the color of a car does not affect the speed at which it travels.
Regarding the question about the rabbit crossing the freeway, the safety of the rabbit cannot be guaranteed even if a car is traveling in the furthest lane, as there are many variables at play, including the behavior of drivers in other lanes and the rabbit's own actions. Concerning the question of whether it is safe to cross the road if a car is 28 meters away: this depends on the car's speed, the pedestrian's speed, and environmental conditions. As a rule, it is always best to cross at designated pedestrian crossings when possible and to wait for traffic to clear.
