Driver's License Test Prep
California Practice Sharing the Road

On a divided highway with four or more lanes going in one direction, in which lanes may a large vehicle be driven?

  1. A.
    Only the far-right lane
  2. B.
    The two lanes farthest to the right Correct
  3. C.
    Any lane except the far-left lane
The Why

The answer is "The two lanes farthest to the right"

The manual restricts large vehicles to the two lanes farthest to the right on a divided highway of four or more lanes in one direction, giving them room to maneuver without blocking through traffic. A carries over a rule from states that pin heavy trucks to a single rightmost lane, dropping the second lane California grants.

Why the others miss

The traps in the wrong answers

A. Only the far-right lane

The manual allows two lanes, not one; the far-right lane alone is a narrower rule. This answer carries over a rule from states that pin heavy trucks to a single rightmost lane on multi-lane highways.

C. Any lane except the far-left lane

The manual defines the allowed lanes, not the forbidden ones; this rule would open more space than the manual grants. This answer reads the rule as an exclusion of the leftmost lane rather than an allowance of the two rightmost, which would open three lanes on a four-lane highway instead of two.
