Illinois Practice Passing

According to the manual, what is not allowed when passing another vehicle on the right or the left?

  1. A.
    Passing while it is raining or snowing
  2. B.
    Passing when the road surface is wet
  3. C.
    Passing a vehicle that carries a placard
  4. D.
    Leaving the pavement or main traveled road Correct
The Why

The answer is "Leaving the pavement or main traveled road"

Passing must happen on the pavement, whether you pass on the left or the right. Drivers who pick the wet-road answer are pulling in general slow-down-in-bad-weather advice and treating it as if the manual banned passing whenever conditions turn slippery.

Why the others miss

The traps in the wrong answers

A. Passing while it is raining or snowing

The manual bans off-pavement passing at all times, not just in bad weather. This answer treats the passing rule as one that changes with the forecast, the way headlight rules do.

B. Passing when the road surface is wet

The manual does not tie the passing prohibition to road-surface conditions. This answer applies general slow-down-when-wet advice as if the manual banned passing on wet pavement.

C. Passing a vehicle that carries a placard

A placard warns of hazardous cargo but does not by itself prohibit passing on either side. This answer reads a hazmat placard as a stop-and-hold signal rather than as a warning about the cargo.
