For a vehicle to stop means to achieve a complete cessation of all movement. This definition signifies that the vehicle is no longer in motion at all, which is an important aspect in various legal and safety contexts, such as traffic laws and accident investigations. Understanding that stopping entails halting all forward momentum is crucial for police officers when assessing situations like traffic violations or accident scenes.

The other options may describe scenarios related to reducing speed or temporary pauses, but they do not encompass the full and absolute nature of stopping as defined in legal terms. For instance, slowing down significantly may still leave the vehicle in motion, and being momentarily stationary suggests that it could start moving again shortly. Likewise, parking on the side of the road indicates that the vehicle is intentionally left in place but does not necessarily convey the total absence of movement that a complete stop does.
