1. About how much clear road do you need to pass safely at 55 mph, according to the Montana manual?
Correct answer: About one third of a mile
The pass itself takes roughly ten seconds, and since both you and the oncoming vehicle each cover more than eight hundred feet in that time, you need about a third of a mile.

7. How close to a hill or curve does the manual say you must not begin a pass?

8. With good tires, good brakes, and dry pavement, how much room does it take to see something and stop from 50 mph?
Correct answer: About 400 feet
The manual puts that figure near four hundred feet, roughly a city block, and adds that being unable to see that far means you should not be traveling that fast.

9. The manual compares stopping from 60 mph with stopping from 30 mph. What does it say?
Correct answer: It takes more than three times the distance
Doubling the speed does not merely double the distance; the manual says halting from the higher speed eats up more than three times the room.

10. How do you know it is safe to move back into your lane after overtaking?
Correct answer: When you can see both of that vehicle's headlights in your mirror
The manual gives a visual cue: once both of the passed vehicle's headlights show in your rear-view mirror, there is room to return.

11. How much should a Montana driver slow down on packed snow?
Correct answer: Cut your speed in half
The manual gives three settings: about ten miles an hour off on a wet surface, half your speed on packed snow, and a crawl on ice.

12. The manual uses the word hydroplaning to describe what?
Correct answer: Tires riding up on a film of water rather than gripping
As speed climbs on a wet surface the tires begin to ride up on a layer of water instead of gripping the pavement.
