To ensure **safety** and prevent the vehicle from moving involuntarily, it is important to engage the **parking brake** in most stops. Although a stop is defined as halting the vehicle for less than two minutes, the driver may exit the vehicle and stay close to it. In these situations, the parking brake helps keep the vehicle stationary, especially on inclined surfaces.

Additionally, when stopping on a slope, it is crucial to take additional measures to secure the vehicle. For example, if the vehicle is on an uphill slope, the first gear should be engaged, and if it is on a downhill slope, reverse gear should be engaged. These actions, along with the use of the parking brake, prevent the vehicle from moving accidentally.

In summary, engaging the parking brake is a recommended practice in most stops to ensure that the vehicle remains secure and does not cause dangerous situations.
