Question

what is the difference between a controlled and an uncontrolled intersection?
a controlled intersection has a traffic cop, and an uncontrolled intersection is a dangerous crossing
a controlled intersection has a traffic light or sign, and an uncontrolled intersection does not

Explanation:

To determine the difference between controlled and uncontrolled intersections, we analyze the options:

• The first option is incorrect because controlled intersections are regulated by traffic lights or signs (not just traffic cops), and uncontrolled intersections aren't defined as "dangerous" by lack of cops (they lack traffic control devices like lights/signs).
• The second option is correct as controlled intersections have traffic lights or signs to regulate traffic, while uncontrolled intersections lack such traffic control devices.

Answer:

B. A controlled intersection has a traffic light or sign, and an uncontrolled intersection does not
