ADA paratransit: who qualifies, where it goes, what it costs and how to book

In the United States, every public entity that runs a fixed route bus or rail system has to offer paratransit, a ride for people whose disability keeps them from using that bus or train, at a level of service comparable to the one other riders get (49 CFR Part 37, Subpart F, 37.121(a)). The Department of Transportation’s rule sets what “comparable” means: who qualifies, a service area of 3/4 of a mile around each route and station, a fare of no more than twice the full fixed route fare, and trips you can book the day before (49 CFR Part 37, Subpart F, 37.123 and 37.131). This guide goes through each one, with the section of 49 CFR part 37 it comes from, and ends with how to apply.

This guide summarizes the sources it cites; it is not legal advice. The official texts are the reference.

What ADA paratransit is, and who has to provide it

The Federal Transit Administration describes paratransit as a safety net: Congress recognized that even a fully accessible bus or rail system leaves out some people whose disabilities prevent them from using it (FTA Circular 4710.1, section 8.1). The rule calls it complementary paratransit because it complements the fixed route: it exists wherever and whenever the buses and trains run, and it has to be comparable to them (49 CFR Part 37, Subpart F, 37.121(a) and (b)).

Who qualifies for ADA paratransit

Eligibility depends on whether you can use the bus or train, not on a diagnosis. FTA puts it plainly: it is not based on the type of disability, the mobility aid you use, your age, your income, or whether you can drive, and using a wheelchair does not by itself make someone eligible, because many wheelchair users can ride accessible buses for many or all of their trips (FTA Circular 4710.1, section 9.2.1). The rule names three groups of people with a disability who are ADA paratransit eligible (49 CFR Part 37, Subpart F, 37.123(e)):

The three groups of ADA paratransit eligibility in 49 CFR 37.123(e).
Group Who it covers Section
1. Cannot use the system on your own people who, because of a physical or mental impairment, including a vision impairment, cannot board, ride or get off an accessible vehicle without the help of another person, other than the operator of the lift or boarding device 49 CFR Part 37, Subpart F, 37.123(e)(1)
2. No accessible vehicle or stop people who need a lift or other boarding device and want to travel on a route at a time when no accessible vehicle is running on it; it also covers a stop where boarding with the lift is not possible, a wheelchair the vehicle’s lift cannot carry, and rail lines without an accessible car per train or with key stations not yet accessible 49 CFR Part 37, Subpart F, 37.123(e)(2)
3. Cannot get to or from the stop people with a specific impairment-related condition that prevents them from traveling to a boarding location or from a disembarking location 49 CFR Part 37, Subpart F, 37.123(e)(3)

The third group has a limit written into it. A condition that only makes the trip to the stop harder is not enough; it has to prevent it. And barriers such as distance, terrain, weather or a building the transit agency does not control do not count on their own, but they do when, combined with your condition, they keep you from reaching the stop (49 CFR Part 37, Subpart F, 37.123(e)(3)(i) and (ii)).

FTA’s examples show where that line falls for blind and low-vision riders. Someone with a vision disability who cannot find the way through a complex transit station can qualify under the first group (FTA Circular 4710.1, section 9.2.1, category 1). Under the third, it lists crossing a busy street with constant traffic turning right on red, where there is no audible cue from the flow of traffic, and walking paths without detectable edges, such as open parking lots, close to fast traffic (FTA Circular 4710.1, section 9.2.1, category 3). Among the barriers that, combined with a disability, can make someone eligible, it also lists missing curb ramps, missing sidewalks along busy roads, steep hills, and snow and ice. What a compliant curb ramp, sidewalk and accessible pedestrian signal look like is in their own guides.

The service area: 3/4 of a mile from the route

Paratransit has to go where the bus or train would take you. The rule draws that area around the fixed route (49 CFR Part 37, Subpart F, 37.131(a)):

Minimum ADA paratransit service area in 49 CFR 37.131(a).
Fixed route Minimum service area Section
Bus a corridor 3/4 of a mile wide on each side of each route, plus a circle with a 3/4 mile radius at each end of the route 49 CFR Part 37, Subpart F, 37.131(a)(1)(i)
Bus, core service area where the corridors merge, the small areas left between them are served too 49 CFR Part 37, Subpart F, 37.131(a)(1)(ii) and (iv)
Bus, outside the core the agency may widen corridors up to 1 1/2 miles on each side, based on local circumstances 49 CFR Part 37, Subpart F, 37.131(a)(1)(iii)
Rail a circle with a 3/4 mile radius around each station 49 CFR Part 37, Subpart F, 37.131(a)(2)(i)
Rail, end and outlying stations circles with a radius of up to 1 1/2 miles may be designated 49 CFR Part 37, Subpart F, 37.131(a)(2)(ii)

FTA measures the 3/4 mile as a straight line, as the crow flies, not along the streets (FTA Circular 4710.1, sections 8.4.2 and 8.4.3). Around rail stations, the service goes from any point in one station’s circle to any point in another’s, but not between two points inside the same circle, since that is not a trip anyone would usually take by train (FTA Circular 4710.1, section 8.4.3). Bus rapid transit counts as a bus route (FTA Circular 4710.1, section 8.4.2).

Two more details change the map. Because the hours follow the fixed route, the service area can shrink at night or on Sundays, when some routes stop running (FTA Circular 4710.1, section 8.4.1). And an agency does not have to serve areas outside its jurisdiction where it has no legal authority to operate, though it has to take all practicable steps to serve its whole service area (49 CFR Part 37, Subpart F, 37.131(a)(3)); FTA adds that a political boundary alone is not a legal bar (FTA Circular 4710.1, section 8.4.4).

Booking a ride: the day before, within an hour

  • Next-day service: the agency schedules and provides a trip at any requested time on a given day when you ask for it the day before. Reservations can be taken by an agent or by mechanical means (49 CFR Part 37, Subpart F, 37.131(b)). FTA adds that an agency may not require you to book 24 hours in advance: a Wednesday trip can be requested during business hours on Tuesday (FTA Circular 4710.1, section 8.4.5).
  • When you can call: at least during the normal business hours of the agency’s offices, and at comparable hours on days the offices are closed before a service day, such as a Sunday before a Monday trip (49 CFR Part 37, Subpart F, 37.131(b)(1); FTA Circular 4710.1, section 8.4.5).
  • Pickup time: the agency may negotiate it, but it cannot make you start a trip more than one hour before or after the time you asked for (49 CFR Part 37, Subpart F, 37.131(b)(2)). If you ask for 9 a.m., the offer can be between 8 and 10 a.m., and FTA says a real negotiation takes into account why you cannot leave earlier, for example the end of your workday (FTA Circular 4710.1, section 8.4.5).
  • Booking further ahead: an agency may let you book up to 14 days in advance; it is allowed, not required (49 CFR Part 37, Subpart F, 37.131(b)(4)).
  • Any purpose: the agency cannot restrict or prioritize trips by their purpose (49 CFR Part 37, Subpart F, 37.131(d)). FTA quotes the rule’s appendix: the agency needs to know the origin, the destination, the time and how many people are traveling, not why, and should not even ask (FTA Circular 4710.1, section 8.4.7).
  • No caps or waiting lists: the agency cannot limit the number of trips you get, keep a waiting list, or run the service in a way that significantly limits it, such as substantial numbers of significantly late pickups, trip denials or excessively long trips (49 CFR Part 37, Subpart F, 37.131(f)). Subscription service, the standing rides for regular trips, is the one place where waiting lists and trip purpose priorities are allowed (49 CFR Part 37, Subpart F, 37.133(c)).

ADA paratransit fares: no more than twice the bus fare

ADA paratransit fares in 49 CFR 37.131(c).
Who Fare Section
Eligible rider no more than twice the full fare, without discounts, for a fixed route trip of similar length at a similar time of day; transfer and premium charges of that trip may be counted 49 CFR Part 37, Subpart F, 37.131(c) and (c)(1)
Companion the same fare as the eligible rider they travel with 49 CFR Part 37, Subpart F, 37.131(c)(2)
Personal care attendant free 49 CFR Part 37, Subpart F, 37.131(c)(3)
Agency trips a social service agency or other organization that books guaranteed trips may be charged more 49 CFR Part 37, Subpart F, 37.131(c)(4)

The comparison is with the full fare. FTA treats monthly passes as discounts, so they are not used to set the maximum. Its example: if bus fares run from $1.50 to $3.50, comparable paratransit trips may cost up to $3 and $7; an agency that charges one flat paratransit fare cannot go above twice the lowest full fare, $3 in that example (FTA Circular 4710.1, section 8.4.6). Where both ends of a trip are within 3/4 mile of a free route that a typical rider would take, the paratransit trip is free too (FTA Circular 4710.1, section 8.4.6).

Traveling with a personal care attendant or a companion

How to apply for ADA paratransit

Each agency that has to provide paratransit runs its own eligibility process (49 CFR Part 37, Subpart F, 37.125), so you apply to the agency whose buses or trains you would use; where several agencies coordinate service, FTA says it is appropriate to apply to the one that serves your home (FTA Circular 4710.1, section 9.2.2, note 3). The steps and your rights along the way are the same everywhere:

  1. Ask for the application. Information about the process, the application materials and every notice are available in accessible formats on request (49 CFR Part 37, Subpart F, 37.125(b)). The process may not charge application or user fees, and if you have to travel to an interview or assessment, the agency offers that transportation at no charge (FTA Circular 4710.1, section 9.4.4).
  2. Describe what you can and cannot do on the bus or train. Eligibility rests on your ability to use the fixed route, so the useful details are the trips that you cannot make and why: the station you cannot navigate, the crossing you cannot make safely, the stop you cannot reach (49 CFR Part 37, Subpart F, 37.123(e)).
  3. Wait 21 days at most. If the agency has not decided within 21 days of a complete application, you are treated as eligible and get service until and unless it denies the application (49 CFR Part 37, Subpart F, 37.125(c)); FTA says service begins on the 22nd day (FTA Circular 4710.1, section 9.5.1).
  4. Read the written decision. It is in writing, and a denial states its reasons (49 CFR Part 37, Subpart F, 37.125(d)). If you are eligible, you receive documentation with your name, the transit provider, the phone number of its paratransit coordinator, an expiration date and any conditions, including the use of an attendant (49 CFR Part 37, Subpart F, 37.125(e)).
  5. Appeal if you are denied. The agency has an appeal process with a chance to be heard and a decision by someone not involved in the first one; it may require the appeal within 60 days of the denial, and if it has not decided within 30 days after the appeal process is complete, it provides service until it denies the appeal (49 CFR Part 37, Subpart F, 37.125(g)).
  6. Renew when asked. The agency may require recertification at reasonable intervals (49 CFR Part 37, Subpart F, 37.125(f)).

Two more rules are worth knowing. An agency may suspend service, for a reasonable time, to riders with a pattern or practice of missing scheduled trips, but trips missed for reasons beyond your control, including the operator’s error, do not count, and it has to notify you in writing and let you be heard first (49 CFR Part 37, Subpart F, 37.125(h)). And when you travel, paratransit goes with you: an agency treats as eligible a visitor who shows ADA paratransit eligibility from home, accepts the visitor’s own statement of being unable to use the fixed route if there is none, though it may ask for proof of where the visitor lives and, if the disability is not apparent, of the disability, and provides service for any combination of 21 days in 365 without asking the visitor to apply (49 CFR Part 37, Subpart F, 37.127(c) to (e)). The rest of the trip, from flights to hotels, is in accessible travel.

Stations, stops and the places in between: Braillito Maps

Paratransit exists for the trips the bus or train cannot give you, and many of those come down to one place: a station you cannot find your way through, a stop with no step-free way in, a crossing without a signal you can hear. Braillito Maps is a community map that answers ten questions about each place: step-free entrance or ramp, wide doorway, accessible restroom, accessible parking, tactile paving, braille signage, braille menu, audible signals, guide dogs welcome and a quiet environment.

The checklist works for any place you add, the station you use included. Four of its questions are the ones a rider asks about a station or a stop: whether you can get in without steps, whether there is tactile paving to follow, whether the signs can be read by touch and whether there are audible signals. Each answer is yes, no or no data until someone knows, and the score of a place is the number of yes answers out of ten, always shown with its number, never by color alone.

The map does not decide eligibility and has no question for paratransit itself, so that stays between you and your transit agency. What it can do is show, before you go, whether the station, the café next to the stop or the clinic at the end of the trip will work for you, and whether a guide dog is welcome there.

Frequently asked questions

Who is eligible for ADA paratransit?

People with a disability who cannot board, ride or get off an accessible bus or train without help, who need an accessible vehicle or stop that is not available for their trip, or whose condition prevents them from getting to or from the stop (49 CFR Part 37, Subpart F, 37.123(e)). Eligibility depends on your ability to use the fixed route, not on a diagnosis or a wheelchair (FTA Circular 4710.1, section 9.2.1).

How far does ADA paratransit go?

At least 3/4 of a mile on each side of each bus route and around the ends of the route, and 3/4 of a mile around each rail station; outside the core area, or at end stations, an agency may extend it up to 1 1/2 miles (49 CFR Part 37, Subpart F, 37.131(a)). FTA measures the distance in a straight line (FTA Circular 4710.1, sections 8.4.2 and 8.4.3).

How much does ADA paratransit cost?

No more than twice the full fare for a similar trip on the bus or train at a similar time of day. A personal care attendant rides free, and a companion pays the same fare as you (49 CFR Part 37, Subpart F, 37.131(c)).

How far in advance do I have to book ADA paratransit?

You can book the day before, and the agency has to schedule the trip at the time you ask for, though it may negotiate the pickup within one hour either way (49 CFR Part 37, Subpart F, 37.131(b)). An agency may also let you book up to 14 days ahead (49 CFR Part 37, Subpart F, 37.131(b)(4)).

How long does an ADA paratransit application take?

If the agency has not decided within 21 days of a complete application, you are treated as eligible and get service until and unless it denies the application (49 CFR Part 37, Subpart F, 37.125(c)).

Can I use ADA paratransit when I visit another city?

Yes. An agency treats as eligible a visitor who shows ADA paratransit eligibility from home, and provides service for any combination of 21 days in a 365-day period without asking the visitor to apply (49 CFR Part 37, Subpart F, 37.127(c) and (e)).
