Flooded roads — Louisiana Permit Test
Flooded roads on the Louisiana permit test — 4 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.
Water can hide a washed-out road, and even shallow moving water can sweep a car away.
If you see a flooded roadway ahead, turn around and find another route to get to your destination.
Six inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.
Even water that looks shallow can stall your engine or float your tires off the road.
Remember, 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling and 2 feet of rushing water can carry away most vehicles.
Two feet of rushing water can carry away most vehicles.
Moving water pushes hard against a car and can float it off the road with people inside.
Remember, 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling and 2 feet of rushing water can carry away most vehicles.
If there is no other route around a flooded road, proceed to higher ground and wait for the waters to subside.
Waiting on high ground keeps you safe until the road can be seen and trusted again.
If there is no other route, proceed to higher ground and wait for the waters to subside.
On the test
You see a flooded road ahead. What should you do?
Turn around, use another route. Water can hide a washed-out road, and even shallow moving water can sweep a car away. Class D & E Driver's Guide, p.119: “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.
