**Detention** is an action that is not voluntary and is imposed by external circumstances. This can occur, for example, when a driver is forced to stop their vehicle due to a traffic accident or when required by the authorities to perform alcohol and drug detection tests. In these cases, the detention is not a choice of the driver, but an obligation imposed by the situation or by law.

On the other hand, **parking** and **stopping** are actions that generally depend on the driver's decision. Parking involves leaving the vehicle in a specific place for a period of time, while stopping is a brief halt that the driver chooses to make, for example, to drop off or pick up passengers. Both actions are voluntary and are not forced by external circumstances as detention is.
