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

The definition of "transit facility'' applies only with reference to the TDD requirement of appendix A to this Part. The point of the definition is to exempt from TDD requirements open structures, like bus shelters, or facilities which are not used primarily as transportation stops or terminals. For example, a drug store in a small town may sell intercity bus tickets, and people waiting for the bus may even wait for the bus inside the store. But the drug store's raison d'etre is not to be a bus station. Its transportation function is only incidental. Consequently, its obligations with respect to TDDs would be those required of a place of public accommodation by DOJ rules.
