Due to their immense weight and size, large commercial trucks require a much greater distance to stop than smaller passenger cars.

In South Dakota, bicyclists may use the left turn lane to make a left turn, following the same rules and procedures as a motor vehicle.

This sign indicates that highway workers may be on or very close to the roadway; slow down and be prepared for their presence.

To execute a proper right turn, you must signal your intention, approach the turn in the lane closest to the right curb, and turn into the rightmost lane of the road you are entering.

The octagon (eight-sided) shape is used exclusively for stop signs, requiring drivers to come to a full and complete stop before proceeding.

Alcohol is a depressant that affects the central nervous system, and the first faculty to be impaired is a person's judgment and decision-making ability.

This sign warns of a sharp curve to the right followed immediately by a sharp curve to the left; slow down.

If an oncoming vehicle has its high beams on, you should avoid looking directly at the lights and instead focus on the right edge of the road or the white line to guide your vehicle.

The only way to lower your Blood Alcohol Content is to allow your body time to metabolize the alcohol; coffee or other remedies do not speed up this process.

On slippery surfaces, your vehicle's stopping distance increases significantly, so you must increase your following distance to allow more space to stop safely.

Guide signs, which provide information about destinations, distances, and routes, are typically rectangular and have a green background with white letters.

Drowsiness has effects similar to alcohol, as it slows reaction time, decreases awareness, and impairs a driver's judgment and ability to make safe decisions.

This is a regulatory sign that directs slower-moving traffic to stay in the right-hand lane on multi-lane roads.

On any multi-lane roadway, including expressways, you must use your turn signal to communicate your intention to change lanes to other drivers.

In South Dakota, it is illegal for a person 21 years of age or older to operate a motor vehicle with a Blood Alcohol Concentration (BAC) of 0.08% or higher.

Your Blood Alcohol Concentration (BAC) is determined by multiple factors, including the amount of alcohol you consume, your body weight, and the time period over which you drink.

This sign marks a parking space reserved for vehicles displaying a valid disabled parking permit or license plate.

At night, visibility is reduced, so you should increase your following distance to at least three to four seconds to allow for more time to react to hazards.

Before slowing down or stopping, you should always check your rearview and side mirrors to be aware of traffic behind you and avoid a potential rear-end collision.

This sign warns that a four-way intersection is ahead; be prepared for crossing traffic.

Under South Dakota law, when you see or hear an emergency vehicle with its lights and siren activated, you must immediately pull over to the right side of the road and stop.

Vehicles entering a roundabout or traffic circle must yield the right-of-way to traffic already circulating within the intersection.

To avoid skidding on snow and ice, all driver inputs—braking, accelerating, and turning—should be done slowly and gently to maintain traction.

It is illegal and dangerous to pass a vehicle stopped at a crosswalk, as the driver may be yielding to a pedestrian you cannot see.

The yield sign is a downward-pointing triangle with a white background, a thick red border, and the word "YIELD" in red letters.

If you feel tired or drowsy while driving, the only safe course of action is to pull over to a safe location and get some rest before continuing.

Broken yellow centerlines separate lanes of traffic moving in opposite directions and indicate that passing is permitted from either direction when it is safe.
