Final answer:
Vision, hearing, and posture changes with age increase the risks for older individuals when crossing streets, as they can affect their ability to see, hear, and move effectively. Accommodations should be made to ensure their safety. Option b is correct.
Step-by-step explanation:
Changes in vision, hearing, and posture can predispose older individuals to being struck by a vehicle. As people age, their risk for accidents increases due to a decline in certain cognitive and physical abilities. For example, an older person's vision may deteriorate, making it harder to see oncoming traffic or judge distances correctly.
Hearing loss can prevent them from noticing approaching vehicles, and changes in posture or balance can make it more difficult to move quickly out of the way. Furthermore, cognitive changes such as difficulty with planning and executing tasks, or poor judgment, may lead to an increased risk of being involved in traffic accidents.
It's important to consider these factors and provide appropriate accommodations, like ample crossing times at pedestrian lights, to enhance safety for the elderly population
