On a multilane road, where does the manual require slow vehicles to travel?
-
A.
In any lane, as long as the hazard flashers are on.
-
B.
In the left-hand lane, so faster traffic can pass on the right.
-
C.
In the center lane, halfway between fast and exiting traffic.
-
D.
In the right-hand lane, except when passing or turning left. Correct
The answer is "In the right-hand lane, except when passing or turning left."
Slow vehicles belong in the right-hand lane on a multilane road; the manual allows a departure from that lane only for passing or setting up a left turn. B reverses the rule, a slip drivers make when they read 'slower traffic keep right' signs as 'slower traffic keep left' under pressure.
The traps in the wrong answers
A. In any lane, as long as the hazard flashers are on.
Hazard flashers do not excuse a slow vehicle from the right-lane rule. This answer treats hazard flashers as a substitute for lane discipline, a habit borrowed from stopped-vehicle rules.
B. In the left-hand lane, so faster traffic can pass on the right.
The manual keeps slower traffic to the right and reserves the left lane for passing. This answer reverses the keep-right rule, a slip made when the roadside sign gets read as 'slower traffic keep left'.
C. In the center lane, halfway between fast and exiting traffic.
The manual creates no center-lane home for slow vehicles. This answer invents a center-lane compromise the manual does not offer.
