Wherever they can. Many will pick spots along their routes where they know they can use the restroom without too many problems. Some may employ adult diapers, especially in situations where going to the bathroom can cost you fares and tips.

Taxi drivers often face a logistical challenge when nature calls while they are on shift. Most drivers rely on a network of accessible public and semi-public facilities. Common locations include gas stations, fast-food restaurants (like McDonald’s), and large hotel lobbies, where the restrooms are generally clean and open 24/7. In major cities, drivers often utilize designated "taxi relief stands" or airport holding lots that are specifically equipped with restrooms and water fountains for commercial operators. Some drivers also frequent public libraries, community centers, or hospitals. Experienced drivers often develop a mental map of "safe" restrooms where they can park their vehicle without the risk of a ticket. In extreme cases or during late-night shifts when options are limited, many rely on the kindness of local businesses or even "members-only" gyms where they might hold a pass. Finding a clean, accessible bathroom is a critical part of a taxi driver’s daily operational strategy to maintain comfort and productivity.
