Driver's License Test Prep
Pennsylvania Practice Safety Belts & Restraints

You need to transport an infant in a rear-facing safety seat. Where does the manual say the seat must not be installed?

  1. A.
    Directly behind the driver on any trip longer than 30 miles.
  2. B.
    In any seating position that lacks a headrest.
  3. C.
    In the front seat when a passenger-side air bag is present. Correct
  4. D.
    In the back seat of a two-door vehicle.
The Why

The answer is "In the front seat when a passenger-side air bag is present."

A deploying passenger-side air bag strikes the back of a rear-facing seat with enough force to injure or kill an infant, so the manual bars installing one in the front seat when an air bag is present. Choice D tempts drivers who take a general kids-in-the-back-seat recommendation and stretch it into a two-door-specific rule; the prohibition is about the air bag, not the vehicle's door count.

Why the others miss

The traps in the wrong answers

A. Directly behind the driver on any trip longer than 30 miles.

Trip length is not a factor in Pennsylvania's install rules. This answer invents a distance threshold to match a mental image of 'long trips are riskier.'

B. In any seating position that lacks a headrest.

The install rule is about air bags, not headrests, which serve adult passengers. This answer borrows the adult head-restraint guidance and misapplies it to infant seats.

D. In the back seat of a two-door vehicle.

The manual endorses back-seat installation regardless of body style. This answer assumes two-door access makes the rear seat unsafe and invents a body-style rule the manual does not state.
