On a multi-lane roundabout, which lane does the manual say drivers typically use to take the first exit to the right?
-
A.
Either lane, as long as you signal before the exit
-
B.
Whichever lane is emptier when you approach
-
C.
The left lane, then merge across at the exit
-
D.
The right lane, chosen before entering the roundabout Correct
The answer is "The right lane, chosen before entering the roundabout"
The manual says you will typically be in the right lane to exit right, and it tells you to observe signs and pavement markings and pick the appropriate lane before entering. Lane changes inside the roundabout are banned, so the choice has to be made at the entry. Drivers who carry freeway habits into the roundabout pick C, staying in a faster left lane and planning to cross over near the exit, which is exactly the mid-roundabout lane change the manual rules out.
The traps in the wrong answers
A. Either lane, as long as you signal before the exit
The manual tells you to observe signs and pavement markings and choose the appropriate lane before entering, and lane changes inside the roundabout are not allowed, so a signal cannot stand in for the entry-lane choice. Treats a turn signal as permission to exit from either lane, when the manual places the discipline at the entry.
B. Whichever lane is emptier when you approach
Lane choice at a roundabout is set by the movement you plan and by the posted signs and pavement markings, not by which lane has fewer cars. Picks the shorter queue without checking that the chosen lane permits the intended movement.
C. The left lane, then merge across at the exit
The manual says do not change lanes while in the roundabout, so moving from left to right inside is exactly the move that is banned. Imports the freeway off-ramp habit of riding the left lane and crossing right near the exit, which the no-lane-change rule inside the circle forbids.
