Pennsylvania Practice Traffic Lights

What does the manual say about the green signal at a ramp-metering light?

  1. A.
    It gives you the right of way onto the highway
  2. B.
    It requires highway traffic to slow and let you merge
  3. C.
    It clears a metered gap in mainline traffic
  4. D.
    It does not protect your entrance; you must still find a safe gap Correct
The Why

The answer is "It does not protect your entrance; you must still find a safe gap"

The green at a ramp meter does not grant right-of-way; drivers must still find a safe gap in mainline traffic. The pull toward A comes from reading any green signal as automatic permission to proceed, regardless of context.

Why the others miss

The traps in the wrong answers

A. It gives you the right of way onto the highway

A ramp-meter green does not confer right-of-way over mainline traffic. This answer reads any green signal as automatic right-of-way regardless of context.

B. It requires highway traffic to slow and let you merge

Mainline drivers are not signaled to yield to metered ramp traffic. This answer confuses ramp metering with a driver-assist merge system that does not exist.

C. It clears a metered gap in mainline traffic

Ramp meters control ramp release only, not mainline spacing. This answer imagines a coordinated gap-creation feature ramp meters do not perform.
