Motorcycle visibility — South Dakota Permit Test
Motorcycle visibility on the South Dakota permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Motorcycles are small and harder to see, so always check mirrors and blind spots for them.
A bike fits inside a blind spot that would show part of a car, so a quick glance misses it.
Motorcycles are small and therefore more difficult to see.
Before turning left, be alert for motorcycles by looking carefully to the front and sides of the vehicle.
Drivers turning left often miss an oncoming bike and turn right across its path.
Before turning left, be alert for motorcycles by looking carefully to the front and sides of the vehicle.
Do not assume a motorcycle is turning when its turn signal is flashing; motorcycle signals may not self-cancel. Wait to be sure the rider is going to turn.
A driver who pulls out because a bike is signaling gets hit when the rider goes straight.
Do not assume a motorcycle is turning when you see its turn signal flashing.
Scooters and mopeds travel at much lower speeds than motorcycles.
A driver who expects a scooter to keep up with traffic closes on it fast and hits it from behind.
Keep in mind that scooters and mopeds travel at much lower speeds than motorcycles.
On the test
An oncoming motorcycle has its turn signal flashing. What should you do?
Wait to be sure the rider will turn. A driver who pulls out because a bike is signaling gets hit when the rider goes straight. South Dakota Driver License Manual, p.62: “Do not assume a motorcycle is turning when you see its turn signal flashing.”
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.
