Sharing the road with slow moving vehicles — Tennessee Permit Test

Sharing the road with slow moving vehicles on the Tennessee permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Farm machinery on the road usually travels at less than 25 mph.

Coming over a hill at 55 mph, you close on a tractor going 25 mph very fast. Expect it so you can slow in time.

In most cases, these vehicles will be traveling at less than 25 M.P.H.

Tennessee Comprehensive Driver License Manual, p.111

Farm machinery usually has no turn signals, and to turn right the operator may first pull wide to the left.

A tractor drifting left looks like it is letting you pass. Passing then puts you right where it swings back to turn.

Farm machinery usually does not have turn signals and to make a right turn, operators of farm machinery may first pull wide to the left, then turn to the right.

Tennessee Comprehensive Driver License Manual, p.111

Animal-drawn vehicles have the same right to use the road as motor vehicles and must follow the same rules of the road.

A buggy is not a hazard to be pushed aside. Its riders have the same right to the lane, and they are badly hurt if hit.

They have the same rights to use the road as a motor vehicle and must follow the same rules of the road.

Tennessee Comprehensive Driver License Manual, p.111

Do not sound your horn or rev your engine loudly when approaching or passing a horse.

A loud noise can make a horse bolt into the road or throw its rider, right in front of your car.

Do NOT sound your horn or “rev” your engine loudly when approaching or passing a horse.

Tennessee Comprehensive Driver License Manual, p.111

When lights are required on slow-moving vehicles, a red lamp on the rear is normally visible for 500 feet to the rear.

At night a red lamp may be your only clue to a slow tractor. Knowing how far it shows tells you how little time you have to slow.

When lights are required for these slow moving vehicles, a self-luminous red lamp on the rear of the vehicle is normally visible for 500 feet to the rear.

Tennessee Comprehensive Driver License Manual, p.112

Before passing a slow-moving vehicle, stay a safe distance behind until it is safe to pass, and be sure the driver has seen you and knows you intend to pass.

Slow vehicles can turn left into unmarked fields at any time. If the driver does not know you are there, you may meet them mid-turn.

When approaching from the rear, stay a safe distance behind the vehicle until it is safe to pass, then be certain the driver has seen you and is aware of your intent to pass before you begin.

On the test

In most cases, how fast does farm machinery travel on the road?

Less than 25 mph. Coming over a hill at 55 mph, you close on a tractor going 25 mph very fast. Expect it so you can slow in time. Tennessee Comprehensive Driver License Manual, p.111: “In most cases, these vehicles will be traveling at less than 25 M.P.H.”

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.
