Final answer:
Legally, you can pass on a two-lane, two-way road when it can be done safely within marked passing zones and without exceeding the speed limit. It's advisable to pass only when visibility is clear and not near intersections, curves, or hills.
Step-by-step explanation:
It is legal to pass slow-moving vehicles on a two-lane, two-way road when the pass can be made safely and without exceeding the speed limit. In general, you should only pass when there are no upcoming intersections, curves, or hills that obstruct your view. Also, many jurisdictions have marked passing zones on these roads, usually indicated by dashed yellow lines on the American roadway system. It's crucial to only pass in these designated areas. Moreover, if the slow vehicle is going below the minimum speed limit and impeding the normal flow of traffic, passing becomes more justified.
It's essential to follow your area's specific traffic laws regarding passing on two-lane roads. Tailgating and honking impatiently, as described in Peter's situation, are not encouraged because they can escalate into aggressive driving behaviors. Instead, securely passing when permitted is the appropriate course of action to overtake slower traffic safely.
