Wet road traction — Louisiana Permit Test
Wet road traction on the Louisiana permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
On wet roads, try to drive in the tire tracks left by the cars in front of you.
Those tracks have less standing water, so your tires keep better contact with the road.
Try to drive in the tire tracks left by the cars in front of you.
ESP stands for Electronic Stability Program; when it senses traction problems, it applies individual brakes to reduce the chance of a skid.
The system can brake one wheel faster and more exactly than a driver, helping keep the car on its path.
When ESP senses traction problems between the two, it selectively applies any one of the vehicle brakes to reduce the possibility of a skid and helps the driver to maintain control and stability of the vehicle.
On the test
On a wet road, where does the manual suggest you drive?
In the tire tracks of cars ahead. Those tracks have less standing water, so your tires keep better contact with the road. Class D & E Driver's Guide, p.116: “Try to drive in the tire tracks left by the cars in front of you.”
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.
