Modified ride-on cars are used by young children with disabilities for self-directed mobility. Purpose: The purpose of this study is to (1) determine the association between modified ride-on car driving time, family income, and primary caregiver education level; and (2) compare modified ride-on car driving time, family income, and primary caregiver education level between High Use and Low Use groups in the study. Method: The amount of time fourteen children with disabilities utilized modified ride-on cars during a three-month study period was recorded and analyzed according to family income and primary caregiver education level. Results: Driving time and family income, as well as family income and primary caregiver education level were correlated but driving time and primary caregiver education level were not. Between the High Use and Low Use groups, driving time was significantly different, but no significant differences were demonstrated in family income or between primary caregiver education level. Conclusion: A child’s access to and usage of modified ride-on cars is impacted by intersectional factors beyond their disability. Effective rehabilitation interventions should consider factors such as family income and parental education level when working to address the physical or cognitive development of children with disabilities. Key words: modified ride-on car, family income, primary caregiver education level, driving tim
