Farm machinery and horses — South Dakota Permit Test

On the test
Why must you take care when passing farm machinery?
The operator cannot hear vehicles coming. A tractor driver who cannot hear you may turn across the road just as you pull out to pass. South Dakota Driver License Manual, p.65: “Pass with caution and remember that the operator of the farm machinery cannot hear approaching vehicles.”
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.
