49 CFR Parts 37 & 38 - Department of Transportation (DOT) ADA Regulations

11. Outside of the Service Area or Operating Hours.

A person's request for fixed route or paratransit service may be denied when honoring the request would require the transportation provider to travel outside of its service area or to operate outside of its operating hours. This request would not be a reasonable modification because it would constitute a fundamental alteration of the entity's service.
