Red traffic signals — South Dakota Permit Test

Red traffic signals on the South Dakota permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

A steady red light means come to a complete stop and wait until the light turns green and there is no crossing traffic before you go.

Creeping on red into the crossing puts you in front of traffic that has the green.

A steady RED traffic light means come to a complete stop.

South Dakota Driver License Manual, p.32

You may turn right on a steady red light after coming to a complete stop, if it is safe and no sign prohibits turning on red.

A rolling right on red catches the walker who stepped off the curb as you looked left.

If you are turning right, you may turn after coming to a complete stop if it is safe to do so and if there is no sign prohibiting turning on a red light.

South Dakota Driver License Manual, p.32

When turning on red, stop first and yield to all traffic, including pedestrians, bicyclists, and cars, then proceed while staying in your lane.

Swinging wide into the far lane on a red turn can put you in the path of a car coming through.

When turning on red, stop first, yield to all traffic including pedestrians, bicyclists, and cars before proceeding safely and staying in your lane.

South Dakota Driver License Manual, p.32

A flashing red light means the same as a stop sign: come to a complete stop, then go when it is safe.

Treating a flashing red like a yellow sends you through a crossing where other drivers have no stop.

A flashing RED traffic light means the same as a stop sign.

South Dakota Driver License Manual, p.32

A red arrow means you must stop and cannot go in the direction of the arrow; you may go when the red arrow goes out and a green arrow or light comes on.

Turning on a red arrow puts you across lanes that have a green light at full speed.

A RED arrow means you must stop and that you cannot go in the direction of the arrow.

On the test

At a steady red light, when may you go straight ahead?

After it turns green and crossing traffic is clear. Creeping on red into the crossing puts you in front of traffic that has the green. South Dakota Driver License Manual, p.32: “A steady RED traffic light means come to a complete stop.”

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.
