Blind spots are areas around your vehicle that you cannot see by using your mirrors. Check your blind spots by turning your head and glancing over your shoulders.

Warning signs are usually yellow with black markings. This sign warns drivers that the upcoming road will curve right, followed by a curve to the left. Drivers should adjust their speed to safely continue on the road.

An octagonal (eight-sided) sign always means "stop." You must always come to a complete stop at this sign.

When parking uphill on a road that has a curb, your wheels should be turned away from the curb. When parking uphill on a street without a curb or when parking downhill, your wheels should be turned toward the curb or edge of the road.

You may proceed in the direction that a green arrow signal is pointing if you are in the proper lane, regardless of any other signals that are displayed. Before turning, you must yield the right-of-way to pedestrians and vehicles already within the intersection.

Slow down before you enter a curve because you do not know what may be ahead. Braking on a curve may cause you to skid.

An octagonal (eight-sided) sign always means "Stop." Come to a complete stop, yield to traffic and pedestrians that have the right-of-way, and proceed when the way is clear.

When traffic permits, you should make room to allow vehicles to merge into your lane.

Regulatory signs inform drivers of specific laws that must be obeyed. Displayed laws may be about traffic direction, lane use, turning, speed, parking, or special situations. Regulatory signs are commonly white squares or rectangles with black, red, or green letters or symbols.

Warning signs are usually yellow with black markings. This sign indicates that there could be traffic merging from the right, so drivers should prepare to allow traffic to safely merge.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

Drivers making left turns must yield to oncoming traffic that is traveling straight. Drivers must always yield to pedestrians.

A five-sided yellow or yellow-green sign alerts drivers to either a school zone or school crossing.

Pedestrians have the right-of-way at street crossings but must obey traffic control signals. Where a traffic signal is not present, vehicles must stop for pedestrians in a crosswalk, whether it is marked or unmarked.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning signal. Use caution when driving near railroad tracks.

With decreased visibility and the glare of oncoming headlights, you cannot see as far ahead at night as you can during the day. Always use headlights and exercise caution when driving in the dark.

This sign indicates that the right lane ends ahead. A merging maneuver will be required for drivers in that lane.

At a yield sign, you must slow down or stop, if necessary, and give the right-of-way to crossing or merging vehicles. Yield the right-of-way to any cross traffic that is close enough to cause conflict.

Certain offenses committed while driving will count against a driver in South Dakota's system of suspending driver licenses. If a driver accrues 22 points or more within a 24-month period, their license will be suspended. Lengths of suspension vary based on how many offenses the driver has committed.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers of an upcoming steep hill. Drivers should adjust their speed accordingly to avoid collisions and brake damage.

You must yield to pedestrians at all times. If the pedestrians are jaywalking or crossing the street where they should not be, you must still stop for them.

Watch for any pedestrian who may cross your path. If you see pedestrians near the road where you are driving, slow down and be prepared to stop, if necessary.

Even if the light is green, you may not enter an intersection unless you can get completely across before the light turns red. If you block the intersection, you can be cited.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

If you are in a lane corresponding to a signal displaying a green arrow, you may proceed in the direction of the arrow when the way is clear. This is true whether the arrow is displayed alone or together with another signal.
