A transportation barrier is any obstacle that prevents a person from getting where they need to go for daily life, whether that’s a medical appointment, a job, a pharmacy, or a grocery store. In 2022, 5.7% of U.S. adults reported that a lack of reliable transportation kept them from medical appointments, work, meetings, or getting things they needed for daily living. That translates to millions of people whose health and livelihood suffer because they simply can’t get from point A to point B.
Transportation barriers are recognized as a social determinant of health, meaning they shape health outcomes just as powerfully as diet, genetics, or access to insurance. The barrier isn’t always about not owning a car. It can involve cost, distance, physical accessibility, unreliable public transit, or living in an area where services are spread far apart.
Types of Transportation Barriers
Transportation barriers fall into several overlapping categories. Financial barriers are among the most common: the cost of gas, car maintenance, insurance, or even a bus fare can be enough to keep someone from making a trip. Geographic barriers affect people who live far from the services they need, particularly in rural areas where the nearest clinic or specialist may be an hour’s drive away and public transit is sparse or nonexistent. Infrastructure barriers show up in cities too, where bus routes may not connect residential neighborhoods to medical centers, or where schedules don’t align with appointment times.
Physical and accessibility barriers are a distinct category. For people who use wheelchairs or have mobility limitations, the challenges go beyond getting a ride. Medical facilities may have doorways too narrow for a wheelchair, exam tables that can’t lower to wheelchair height (accessible tables lower to 17 to 19 inches from the floor), or imaging equipment designed for patients who can stand. Even when a ride is available, the vehicle itself may not accommodate a wheelchair or mobility device.
Then there are what might be called life-circumstance barriers. A parent without childcare can’t easily spend three hours on buses to reach an appointment. A person working hourly shifts may not be able to take time off for the travel involved. These factors compound each other: a low-income worker in a rural area without a car faces financial, geographic, and scheduling barriers simultaneously.
Who Is Most Affected
Transportation barriers do not hit all groups equally. Income is the single strongest predictor. Among adults living below the federal poverty line, 15.8% reported lacking reliable transportation, compared to just 2.9% of those with incomes at four times the poverty level or higher. That’s more than a fivefold difference.
Racial and ethnic disparities are also stark. American Indian and Alaska Native adults reported the highest rate of unreliable transportation at 17.1%. Black adults followed at 9.2%, compared to 4.8% among white adults. Hispanic adults fell in between at 6.9%. These gaps reflect broader inequities in infrastructure investment, housing patterns, and economic opportunity.
Age and education matter as well. Younger adults (ages 18 to 34) reported transportation problems at a rate of 7.0%, while adults 65 and older reported 4.5%, likely because older adults qualify for more transportation assistance programs. Adults without a high school diploma reported barriers at 9.7%, dropping to 3.8% among those with a college degree. Women (6.1%) were slightly more likely than men (5.3%) to report the problem, a gap that likely reflects differences in car ownership, caregiving responsibilities, and income.
Geography plays a role too. Rates were highest in the West North Central region of the U.S. (7.5%) and lowest in New England (4.1%).
How Transportation Barriers Affect Health
Transportation barriers are responsible for an estimated 25% or more of missed clinic appointments. In 2017, 5.8 million Americans delayed medical care specifically because they lacked transportation. The consequences ripple outward: missed preventive screenings, delayed diagnoses, unfilled prescriptions, and poorly managed chronic conditions.
People with unmet transportation needs are 2.6 times more likely to report multiple emergency room visits in a year compared to those with reliable transportation. This pattern makes sense. When you can’t get to a primary care doctor for routine management of a condition like diabetes or high blood pressure, minor problems escalate until they become emergencies. ER visits are more expensive and less effective for ongoing care, creating a costly cycle for both patients and the healthcare system.
Chronic disease management is where the impact is most visible. Conditions like kidney disease requiring dialysis, diabetes requiring regular monitoring, and mental health conditions requiring consistent therapy all depend on the patient showing up repeatedly over months and years. One participant in a Medicaid transportation study who missed dialysis appointments because she lacked a ride during the COVID-19 pandemic ended up hospitalized as a result. Others in the same study described reliable transportation as the difference between “life or death.”
Rural Versus Urban Challenges
Rural and urban residents face transportation barriers for fundamentally different reasons. In rural areas, the core problem is distance and the absence of alternatives. Public transit systems are sparse or nonexistent, private taxi services are limited, and the nearest specialist may require a long drive. When a rural hospital closes or a provider leaves, travel times can increase dramatically with no fallback option.
Urban residents generally have more transportation options, including buses, trains, and rideshare services. But availability doesn’t always mean accessibility. Routes may not serve the neighborhoods where low-income residents live. Schedules may not align with medical appointments. Highway congestion can turn a short distance into a long trip. And for people with mobility limitations, even a nearby bus stop is useless if the sidewalk, the bus, or the destination itself isn’t accessible.
Programs That Help
Medicaid’s Non-Emergency Medical Transportation (NEMT) benefit is one of the largest programs addressing this problem. It provides rides to and from medical appointments for Medicaid beneficiaries who have no other way to get there. Participants in a study of the program described it as critical for managing both physical and mental health. Several people with disabilities emphasized that NEMT gave them a sense of independence they wouldn’t otherwise have, reducing their reliance on friends and family and helping them leave the house for therapy, day programs, and other appointments that provide human connection.
The emotional dimension is often overlooked. Being unable to get around doesn’t just delay medical care. It isolates people. Participants in the NEMT study talked about the emotional toll of being confined to their homes, and how having reliable transportation enriched their lives well beyond the medical appointments themselves.
How Telehealth Fills the Gap
Telehealth has emerged as a significant workaround for transportation barriers, particularly since the COVID-19 pandemic expanded its availability. In one study, 78.3% of people who used telehealth said it made getting medical care easier because it eliminated the need to travel. That finding held fairly consistently across age groups, income levels, and disability status.
People who face the steepest transportation challenges adopted telehealth at the highest rates. Those with known transportation barriers used telehealth at a rate of 82.4%, and those without a household vehicle or with very long travel times to their provider also reported higher use. Patients described avoiding canceled appointments they would have otherwise missed due to pain, illness, or lack of a ride. Others pointed to savings in gas money and time, especially those who normally drive long distances to see a specialist.
Telehealth has clear limits. It can’t replace a physical exam, blood work, imaging, dialysis, or any hands-on procedure. But for routine check-ins, mental health therapy, medication management, and follow-up visits, it removes the transportation barrier entirely. For many people, that’s the difference between getting care and going without.
