Hills narrow roads and blowouts — Minnesota Permit Test
Hills narrow roads and blowouts on the Minnesota permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
On a narrow road where brush or trees block your view of a curve, you can use your horn to warn others.
The horn reaches around the corner, which is more than your headlights do.
When you approach curves on narrow roads, or in areas where brush and trees block your view of the road ahead, you can use your horn to warn other drivers or pedestrians that you are on the road.
Do not coast down steep hills with the transmission in neutral.
In neutral the engine is doing nothing to hold the car back, so the brakes do all of it and overheat.
Do not coast down steep hills with your transmission in neutral.
On steep hills check your speedometer often, because speed climbs even with your foot off the accelerator.
Gravity does the accelerating, and the car feels the same the whole time.
On steep hills, check your speedometer frequently. Vehicle speed will increase even when your foot is not on the accelerator.
Before a blowout you may hear a thumping sound or feel the steering wheel pulling to one side.
The tire usually gives some warning, and pulling over on the warning is much easier than after.
Before a blowout occurs, you may hear a thumping sound or notice the steering wheel pulling to the right or left.
In a blowout, hold the wheel tightly, steer straight ahead and ease off the accelerator without braking until you have control.
Braking on a burst tire drags the car toward that corner, which is how a blowout becomes a rollover.
If you experience a blowout, hold the steering wheel tightly, steer straight ahead and slowly ease your foot off the accelerator. Do not brake until the vehicle is back under your control.
On the test
What can you use on a blind curve on a narrow road?
Your horn, to warn others. The horn reaches around the corner, which is more than your headlights do. Minnesota Driver’s Manual, p.82: “When you approach curves on narrow roads, or in areas where brush and trees block your view of the road ahead, you can use your horn to warn other drivers or pedestrians that you are on the road.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
