Final answer:
It is generally false that one can legally exceed the speed limit when passing another vehicle, as local traffic laws may differ. The de jure speed limit is the enforceable legal limit, regardless of the de facto speed limit.
Step-by-step explanation:
The statement that it is legal to go faster than the speed limit when passing another vehicle is generally false. Speed limits are set to maximize safety for all road users, and going over the speed limit can be considered a traffic violation. This rule can vary depending on the state or country, as some places may have specific passing laws that allow exceeding the speed limit slightly during overtaking maneuvers. However, it is crucial to know the local traffic laws to understand what is permitted. Additionally, irrespective of the de facto speed limit, which may be the speed at which police typically enforce, the de jure speed limit is the legal limit stated on traffic signs, and adherence to this is a legal requirement.
