Final answer:
It is true that drivers should stop their vehicles before entering the intersection at a stop sign without a marked crosswalk. This traffic rule aids in ensuring pedestrian safety and reducing the likelihood of accidents.
Step-by-step explanation:
When approaching a stop sign that is not marked by a crosswalk, drivers should stop their vehicles before entering the intersection. This is true. It is a basic traffic rule that ensures both pedestrian safety and the smooth flow of traffic. Failing to stop at a stop sign can lead to severe consequences, such as causing an accident or receiving a fine. In many areas, the law stipulates that drivers must come to a complete stop at the stop line before proceeding. If there is no stop line, drivers must stop before entering the crosswalk area or if there is no crosswalk, before entering the intersection itself. This rule is crucial for preventing accidents, as stated in model cause-and-effect paragraphs where the absence of a traffic signal led to increased vehicle speeds and a rise in accidents.
