License restrictions — South Dakota Permit Test
License restrictions on the South Dakota permit test — 1 rule, each with the reason behind it and a question on it while it is fresh.
The rules
An operator license may be issued with restrictions; for example, a person who cannot see clearly with their right eye is restricted to a vehicle with a left outside rearview mirror.
A driver weak on one side cannot see cars coming up there, and a mirror on the other side helps fill the gap.
For example, a person who cannot see clearly with their right eye will be restricted to driving a vehicle with a left outside rearview mirror.
On the test
A driver who cannot see clearly with their right eye may be restricted to what?
A left outside rearview mirror. A driver weak on one side cannot see cars coming up there, and a mirror on the other side helps fill the gap. South Dakota Driver License Manual, p.11: “For example, a person who cannot see clearly with their right eye will be restricted to driving a vehicle with a left outside rearview mirror.”
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.
