Parking is not allowed in a lane reserved for buses. These lanes are designed exclusively for the use of buses and, in some cases, taxis. The circulation of other vehicles is prohibited in these lanes, which includes stopping or parking.

- **Reserved lanes**: Bus lanes are a part of the road specifically reserved for certain vehicles, such as buses and taxis. This means that other vehicles are not allowed to use them for stopping or parking.

- **Prohibition of stopping and parking**: It is prohibited to stop and park in lanes or parts of the road that are reserved for other vehicles, such as buses. This ensures that buses can circulate without obstacles and maintain an efficient traffic flow.


Therefore, the correct answer is that you cannot park in a lane reserved for buses.
