Final answer:
Walkers often do not qualify for the Emergency Ride Home program as it is intended for users of alternative transportation methods that could face unforeseen interruptions.
Step-by-step explanation:
The Emergency Ride Home program is typically designed for individuals who use alternative transportation methods regularly and may occasionally need an emergency ride. This service is commonly offered to provide peace of mind to those who carpool, bike, or use public transportation, encouraging the use of sustainable travel options. To determine who does not qualify, it's important to consider the purpose of the program. While carpoolers, bus riders, and bike commuters are likely to qualify because they are using alternative transportation, walkers may not necessarily qualify because they don’t rely on a transportation service or system that can suffer disruptions. Therefore, D) Walkers often do not qualify for Emergency Ride Home programs as they are not using a transportation method that could be subject to unforeseen interruptions needing emergency services.
