Final answer:
When reversing direction, it's important to consider all aspects of traffic density, street layout, and visibility. Safety is paramount, and these factors contribute to making a well-judged and safe maneuver. It's critical to assess the situation carefully whenever crossing the road, even if a car appears to be a safe distance away. The correct answer is D) All of the above.
Step-by-step explanation:
When reversing direction, you should consider D) All of the above: A) Traffic density and speed, B) Street layout and design, and C) Visibility and line of sight. Considering all these factors is important for safety reasons. High traffic density and speed can increase the risk of accidents, while the street layout affects the maneuverability and visibility that the driver has. Adequate visibility and line of sight are critical to ensure that no pedestrians or other obstacles are in the path when reversing.
Regarding the question of whether it is safe to walk across the road when a car is 28 meters away, this depends on various factors such as the speed of the approaching car and your own speed and ability to cross safely. It's generally advisable to cross at designated pedestrian crossings where possible. If the car is traveling in the furthermost lane from a crossing point, and you are certain it will not change lanes unexpectedly, there may be an opportunity to cross safely if you're quick and certain no other cars are approaching. However, caution and judgement should always be exercised to prioritize safety. So, the correct answer is D) All of the above.
