49 CFR Part 37 - Transportation for Individuals With Disabilities; Reasonable Modification of Policies and Practices

4. Obstructions.

For fixed route services, a passenger's request for a driver to position the vehicle to avoid obstructions to the passenger's ability to enter or leave the vehicle at a designated stop location, such as parked cars, snow banks, and construction, should be granted so long as positioning the vehicle to avoid the obstruction does not pose a direct threat. To be granted, such a request should result in the vehicle stopping in reasonably close proximity to the designated stop location. Transportation entities are not required to pick up passengers with disabilities at nondesignated locations. Fixed route operators would not have to establish flag stop or route-deviation policies, as these would be fundamental alterations to a fixed route system rather than reasonable modifications of a system. Likewise, subject to the limitations discussed in the introduction to this appendix, paratransit operators should be flexible in establishing pick up and drop off points to avoid obstructions.
