The number of passengers you can fit in a Lyft depends entirely on the specific ride type you select within the app. A standard Lyft (the most common and affordable option) typically accommodates up to 4 passengers. If you have a larger group, you must book a Lyft XL, which is specifically designed for groups of up to 6 passengers and usually involves a larger SUV or a minivan. It is important to note that these limits are based on the number of available seatbelts in the vehicle; drivers are legally prohibited from carrying more passengers than their car is rated for. Furthermore, if you are carrying significant luggage, you might need to size up even for a small group; for example, four people with four large suitcases will likely not fit in a standard sedan and would be better served by an XL. In some markets, luxury options like Lyft Lux or Black follow the same 4 or 6-passenger rules but offer higher-end vehicles. Always ensure your group fits the limit, as a driver can refuse to start the trip if you exceed the capacity.
