3. On which side should you overtake a tractor-trailer, and how?
Correct answer: On the left, completing the pass without lingering
Pass a rig on its left, and finish the maneuver rather than sitting alongside; loitering beside any vehicle robs the other driver of room to react to an obstacle.

4. How much of a lane should a driver leave to a motorcyclist?
Correct answer: The full width of the lane
A rider is entitled to the whole width of the lane; even though a car and a bike look as if they would fit side by side, the rider needs that space to maneuver.

5. What simple rule tells you whether a truck driver can see your car?
Correct answer: If you cannot spot the driver in a side mirror, the driver cannot spot you
The manual's rule of thumb is that if the trucker is not visible to you in his or her side mirror, then you are not visible to the trucker either.

6. Why do drivers so often misjudge an approaching tractor-trailer at an intersection?
Correct answer: Its size makes it look slower than it actually is
Because of its bulk a rig looks slower than it really is, and many car-truck crashes at intersections trace back to a driver misreading how near or how fast the truck was.

7. When may a North Dakota driver use a marked bicycle lane?
Correct answer: To set up for a right turn, after signaling and looking
Driving in a lane set aside for bicycles is to be avoided except when you are making a right turn, and even then you must signal and look before easing into it.

8. Where do most crashes between a motor vehicle and a bicycle happen?
Correct answer: At intersections
Intersections account for the bulk of bicycle crashes, which is why the manual tells drivers to scan for riders there and give them extra time to get across.

9. Why should you not act immediately on a motorcycle's blinking turn signal?
Correct answer: The signals often fail to cancel on their own
Motorcycle signals commonly do not shut off by themselves, and riders sometimes forget to cancel one, so wait for evidence the rider is really turning.

10. How much following time does the manual recommend behind a motorcycle?
Correct answer: Three or four seconds
Three or four seconds gives the rider room to swerve or brake for a hazard; in dry conditions a motorcycle can actually pull up shorter than a car.

11. Why does a tractor-trailer sometimes swing wide to the left before turning right?
Correct answer: The rear wheels cut a shorter arc than the front wheels
On any turning vehicle the back wheels track a tighter arc than the front ones, and the longer the rig the bigger that gap, so drivers must swing out to clear the corner.

12. In crashes between a motorcycle and another vehicle, what did nearly 40 percent involve?
Correct answer: The other vehicle turning left across the rider's path
About half of motorcycle crashes involve a second vehicle, and close to 40 percent of those were caused by the other driver turning left across the rider's path.
