Illinois Practice Passing

The manual bars passing on a two-lane, two-way road within 100 feet of which structure when the view is blocked?

  1. A.
    A highway rest area entrance
  2. B.
    A bridge, viaduct, or tunnel Correct
  3. C.
    A traffic circle or roundabout
  4. D.
    A parked commercial truck
The Why

The answer is "A bridge, viaduct, or tunnel"

Bridges, viaducts, and tunnels each carry a 100-foot no-passing buffer when they block your view. Drivers who pick the roundabout answer are pattern-matching on 'structures where sight lines close in' without checking which ones the manual actually names.

Why the others miss

The traps in the wrong answers

A. A highway rest area entrance

Rest area entrances are not on the manual's no-passing list. This answer extends the intersection-buffer intuition to any highway feature that involves cross traffic.

C. A traffic circle or roundabout

Roundabouts are not on the manual's no-passing list for two-lane, two-way roads. This answer pattern-matches on 'places where sight lines close in' rather than checking the printed list.

D. A parked commercial truck

The manual does not put a passing buffer around parked commercial trucks. This answer assumes any large object counts as a view blocker under the same rule.
