Flooded roads — Alaska Permit Test
Flooded roads on the Alaska permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Do not drive through flooded areas; if you see a flooded roadway ahead, turn around and find another route.
You cannot tell how deep the water is or whether the road under it is still there.
If you see a flooded roadway ahead, turn around and find another route to get to your destination.
Just 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.
Water under the car can lift the tires off the road or stall the engine, leaving you stuck in the flood.
Remember, 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.
2 feet of moving water can carry away most vehicles, including sport utility vehicles and pickup trucks.
Moving water pushes hard on the whole side of a vehicle, and a big truck can float away as easily as a car.
Two feet of moving water can carry away most vehicles including sport utility vehicles and pick-up trucks.
Even if flood water looks shallow enough to cross, do not try: it can hide dips, or the road surface under it may be washed away.
What looks like a few inches can be a hole or a missing road, and you only find out once you are in it.
Water can hide dips, or worse, floodwaters can damage roadways by washing away the underlying road surface.
If there is no other route around a flood, go to higher ground and wait for the water to go down.
Flood water can rise fast, and higher ground keeps you out of its reach while it drains away.
If there is no other route, proceed to higher ground and wait for the waters to subside.
Flash floods can come rapidly and unexpectedly, within a few minutes or hours of excessive rainfall.
A dry road can turn into a river soon after a storm, so be ready to turn back even when you set out in fine weather.
They can occur within a few minutes or hours of excessive rainfall.
On the test
You see a flooded roadway ahead. What should you do?
Turn around and find another route. You cannot tell how deep the water is or whether the road under it is still there. Alaska Driver Manual, p.84: “If you see a flooded roadway ahead, turn around and find another route to get to your destination.”
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.
