Which method is NOT recommended for stopping a vehicle?

Stopping a vehicle on flat roads is not generally recommended because it can create a safety hazard for both the driver and other road users. Flat roads often lack the necessary visibility and safety measures that are essential when conducting a stop, especially if the vehicle is stationary for an extended period. In contrast, when stopping in intersections, on/off ramps, or curves, there are usually specific safety protocols and traffic regulations designed to manage such situations. Each of those locations may have inherent risks, but they often involve clearer guidelines and more predictable traffic patterns. Flat roads, however, do not provide the same structured environment, potentially leading to dangerous scenarios where other vehicles may not anticipate a sudden stop.
