Motor vehicle transportation, whether in private, public, or school-bus vehicles, is vital in today’s society. Ready access to transportation is not only essential for most occupations and education, but also for accessing healthcare providers, religious services, recreation and leisure activities, shopping, voting, and many other community activities and services. As reported by the National Council on Disability, the need for transportation is even greater for individuals who use wheelchairs, including those who are unable to transfer out of their wheelchair when traveling (Bureau of Transportation Statistics, 2002; National Council on Disability, 2005).
