Submerged vehicle — Louisiana Permit Test
Submerged vehicle on the Louisiana permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If your vehicle enters water, it will float on the surface for only 30 to 60 seconds, so try to get out immediately.
Those first seconds are your best chance to escape before water pressure holds the doors shut.
If your vehicle enters water, it will only float on the surface for 30 to 60 seconds so make every attempt to get out of the vehicle immediately.
If your car goes into water, immediately unbuckle your seat belt and roll the window down; do not wait for the car to fill.
Electric windows may still work for a few seconds, but not once the car is under water.
Immediately unbuckle your seat belt and roll the window down.
To escape a sinking car, kick out a side window, not the windshield, which is designed not to shatter.
Kicking the windshield wastes the few seconds you have, because that glass will not break apart.
Do not try to break or kick out the windshield.
In a sinking car, take off heavy clothing that will make you sink, but keep your shoes on in case you must kick out a window.
Shoes protect your feet and give force to a kick against the glass.
Take off heavy clothing that will cause you to sink, but keep your shoes on in case you have to kick the window to escape.
In a sinking car you cannot open, wait for the pressure to equalize; when the water along the window is at your shoulder, try to open the door.
Water pushing on the outside holds the door shut until the car fills enough to even the pressure.
When the water along the window is to your shoulder, try to open the door.
If there are children in a sinking car, unbuckle the oldest child first and then the younger ones.
Older children need less help, so freeing them first lets them escape while you help the little ones.
If there are children in the car, unbuckle the oldest child first and then the smaller younger ones.
The escape steps for a car in water spell POGO: Pop the seat belt open, Open the windows, Get Out, and do not stay in the car to wait for help.
A short word is easy to remember when you have only seconds and may be scared.
P – Pop the seat belt open.
On the test
If your car goes into water, about how long will it float on the surface?
30 to 60 seconds. Those first seconds are your best chance to escape before water pressure holds the doors shut. Class D & E Driver's Guide, p.119: “If your vehicle enters water, it will only float on the surface for 30 to 60 seconds so make every attempt to get out of the vehicle immediately.”
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.
