Driver's License Test Prep
North Carolina Practice Defensive Driving

Aside from the risk of parked vehicles pulling out or pedestrians darting from between them, what other hazard does the manual say parked vehicles create in the city?

  1. A.
    They leak fluids that make the traffic lane slippery.
  2. B.
    They block your view of intersecting traffic, driveways, and alleys. Correct
  3. C.
    They force through-traffic into a single center lane.
  4. D.
    They mask the sound of sirens from emergency vehicles.
The Why

The answer is "They block your view of intersecting traffic, driveways, and alleys."

Parked vehicles block your view of intersecting traffic, driveways, and alleys, taking away the sight lines a driver needs to spot the next hazard before it moves. Choice D is the trap for a driver who pictures parked cars as a wall that muffles sirens and reaches for an acoustic danger; the manual's concern in this passage is visual, not audio.

Why the others miss

The traps in the wrong answers

A. They leak fluids that make the traffic lane slippery.

Pavement condition is not among the parked-vehicle hazards the manual lists in this passage. This answer carries the image of oil stains under parking-lot spots onto a city street, from the everyday experience of walking past leaks in a lot rather than reading the bullet about what a driver cannot see past the cars.

C. They force through-traffic into a single center lane.

Traffic flow is not the parked-vehicle hazard the manual points to here. This answer borrows the center-lane rule from the very next city-driving bullet, which is about one-way streets, and mistakes it for a general rule about any street with cars parked along it.

D. They mask the sound of sirens from emergency vehicles.

The manual names a visual hazard here, not an acoustic one. This answer reaches for hearing from the habit of listening for sirens with the window cracked, on the assumption that a solid row of parked cars muffles that sound the way a wall would.
