Yes, that's correct. In addition to the standard metered fare, taxi cab services may apply additional charges or surcharges for specific circumstances. These extra charges are designed to account for certain situations or conditions that may affect the cost of the ride. Here are some common examples of additional charges or surcharges that might apply:

1. **Luggage Surcharge:** Taxis may charge an extra fee for carrying larger or heavier luggage. This surcharge compensates the driver for the effort required to handle and load the luggage.

2. **Airport or Station Fees:** Some taxi services apply an additional fee for trips to or from airports, train stations, or other transportation hubs. This fee might cover access or waiting time at these locations.

3. **Late-Night Surcharge:** Taxis operating during late-night hours or during specific "night rates" may have a surcharge applied to fares during these times, as the demand for taxis may be higher.

4. **Peak Hour Surcharge:** During peak traffic hours, when congestion is Taxis braintree high and travel times are longer, taxis might apply a surcharge to account for the increased time spent on the road.

5. **Toll Road Fees:** If the taxi driver takes a route that includes toll roads or bridges, passengers may be required to cover the cost of the tolls as part of the fare.

6. **Holiday Surcharge:** On holidays or festive occasions, some taxi services may impose a surcharge to reflect increased demand.

7. **Extra Passengers:** Taxis may charge an additional fee per passenger beyond a certain number. This is to account for the extra wear and tear on the vehicle and the potential need for a larger vehicle.

8. **Waiting Time:** If a passenger asks the driver to wait for an extended period during the ride (e.g., to make a quick stop), waiting time charges might apply.

9. **Special Requests:** Certain special requests, such as pet transport or specific vehicle accommodations, may lead to additional charges.

It's important for passengers to inquire about any potential extra charges or surcharges before starting the ride. Taxi drivers are usually required to inform passengers about these charges and display them on the meter or provide a clear breakdown on the receipt. Being aware of these potential additional costs can help passengers budget for their taxi ride accurately.
