Slow moving vehicles — Louisiana Permit Test
Slow moving vehicles on the Louisiana permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
An orange and red triangle on the rear of a vehicle drawn by animals, farm equipment or construction equipment means it travels at less than 25 mph.
You will close in on such a vehicle very fast, so the emblem warns you to slow down early.
A fluorescent or reflective orange and red triangle displayed on the rear of vehicles drawn by animals, farm equipment or construction equipment means the vehicle is traveling less than 25 mph.
To make a right turn, a farm machinery operator may pull wide to the left first, since farm machinery usually has no turn signals.
A tractor swinging left may really be about to turn right, so passing it then can cause a crash.
Farm machinery usually does not have turn signals and to make a right turn, operators of farm machinery may pull wide to the left and then turn to the right.
Pass farm machinery with caution, and remember its operator cannot hear approaching vehicles.
A farmer on a loud tractor will not know you are behind, so do not count on being noticed.
Pass with caution and remember the operator of the farm machinery cannot hear approaching vehicles.
Animal-drawn vehicles have the same rights to use the road as motor vehicles and must follow the same rules of the road.
A horse and buggy belongs on the road as much as a car, so drivers must share the lane safely.
They have the same rights to use the road as a motor vehicle and must follow the same rules of the road.
Normal speeds for animal-drawn vehicles range between 5 and 8 mph.
At such low speeds you will come up on a buggy very quickly, so slow down as soon as you see one.
Normal speeds for animal drawn vehicles range between 5 and 8 miles per hour.
When passing an animal-drawn vehicle, do not use your horn or rev the engine, because it may scare the horse and cause a crash.
A frightened horse can bolt into your path or tip the cart it is pulling.
Pass with caution and do not use your horn or “rev” the engine because this may scare the horse and cause a crash.
Anticipate left turns made by animal-drawn vehicles into fields and driveways.
A buggy turning left across your path is a common way for a passing car to hit one.
To avoid other possible collisions, you should anticipate left turns made by animal drawn vehicles into fields and driveways.
Horseback riders must ride single file near the right curb or road edge, or on a usable right shoulder, lane or path.
Riding in a single line at the edge keeps horses out of the main flow of cars.
They must ride single file near the right curb or road edge, or on a usable right shoulder, lane or path.
If you drive a slow-moving vehicle so slowly that traffic behind must slow down, pull to the side of the road when safe and let them pass.
A long line of cars stuck behind you tempts drivers into risky passing.
If you are driving a slow moving vehicle and you have to drive so slowly that other vehicles have to reduce speed to the rear, pull to the side of the roadway when safe to do so and let the other vehicles pass.
On the test
A triangle emblem on the back of a farm vehicle means it is traveling slower than what speed?
25 mph. You will close in on such a vehicle very fast, so the emblem warns you to slow down early. Class D & E Driver's Guide, p.105: “A fluorescent or reflective orange and red triangle displayed on the rear of vehicles drawn by animals, farm equipment or construction equipment means the vehicle is traveling less than 25 mph.”
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.
