Final answer:
The correct action at an intersection without signals or signs is to slow down and proceed with caution, which increases safety for all road users.
Step-by-step explanation:
When two roads intersect without signs or lights as guidance, it's essential to approach the intersection with caution. The correct response would be to slow down and proceed with caution. This is crucial for the safety of both drivers and pedestrians. By slowing down, drivers have more time to observe their surroundings, notice potential hazards, and react accordingly. It also reduces the likelihood of accidents, especially in areas where pedestrians, including students, might be crossing to reach campus or other destinations. Increasing safety measures like installing traffic signals can save lives by reducing traffic and pedestrian accidents significantly.
