Final answer:
True. Drivers must stop at a stop sign before entering an intersection to ensure the safety of all road users and comply with traffic laws. Traffic signals play a crucial role in controlling vehicle speeds and enhancing pedestrian safety.
Step-by-step explanation:
The answer to the question "When approaching a stop sign that is not marked by a crosswalk, drivers should stop their vehicles before entering the intersection." is True. Drivers must come to a complete stop at a stop sign before proceeding through an intersection, even if there is no marked crosswalk. This rule ensures the safety of all road users, including pedestrians and other vehicles that may be approaching from different directions. It is crucial for drivers to obey traffic signals and stop signs to prevent accidents and promote the orderly flow of traffic. Ignoring these traffic controls can lead to serious consequences, such as increased accidents and pedestrian endangerment.
For example, before the installation of a traffic signal at a problematic intersection where vehicles speed and pedestrian safety was an issue, the rate of accidents was high. Once the signal was in place, it effectively made vehicles slow down, allowed pedestrians to cross at appropriate times, and significantly reduced the number of accidents.
