Bus hazards — South Dakota Permit Test

Bus hazards 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

Inter-city buses make frequent stops; if you see a bus ahead, move to another lane before it stops.

Drivers stuck close behind a stopped bus swerve out at the last second into the next lane's traffic.

If you see a bus ahead of you, move to another lane of traffic before the bus stops.

South Dakota Driver License Manual, p.64

When passing a parked bus, do so with care, as the bus may start to move into the lane and pedestrians may run in front of it.

Children and riders dash around a parked bus, and a car passing fast reaches them before they see it.

Additionally, if you are passing a parked bus, do so with care as the bus may start to move out into the lane of traffic.

South Dakota Driver License Manual, p.64

The tail swing on articulated buses, where the rear swings out into traffic, is approximately 3 feet; allow enough room for it.

A car tight beside a bending bus gets swept by the rear section as the bus turns.

The swing on articulated buses is approximately 3 feet.

South Dakota Driver License Manual, p.64

The smaller the vehicle you drive, the harder it is for truck and bus drivers to see you.

A small car fits wholly inside a truck's blind spot, so the driver changes lanes into it.

Remember, the smaller the vehicle being driven, the harder it is for truck and bus drivers to see you.

On the test

About how far can the rear of an articulated bus swing out into traffic?

About 3 feet. A car tight beside a bending bus gets swept by the rear section as the bus turns. South Dakota Driver License Manual, p.64: “The swing on articulated buses is approximately 3 feet.”

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.
