South Dakota Free Test 2

When driving in fog, you should always use your low beam headlights, as high beams will reflect off the fog and create glare, reducing your visibility even further.

To avoid being blinded by an approaching vehicle's high-beam headlights, you should look away from the lights and toward the right edge of your lane.

A broken yellow line separating traffic lanes means that vehicles traveling in either direction are allowed to pass when it is safe to do so.

In case of a steering failure, you should remain calm, activate your hazard lights, and gradually slow down, bringing the vehicle to a stop on the side of the road.

Signs that are brown with white lettering are used to indicate points of public recreation, scenic guidance, and cultural interest.

This sign warns that you are approaching a school zone; slow down, watch for children, and obey any posted school speed limits.

This is a service sign indicating that a hospital is nearby; follow the sign to reach the facility.

Because small children can be difficult to see behind a vehicle using only mirrors, it is safest to physically get out of the car and check the area before backing up.

Signs with a green background and white letters are guide signs that provide directional information, such as distances to upcoming destinations.

To ensure a lane change is safe, you must physically turn your head and look over your shoulder to check the blind spot in the direction you plan to move.

A flashing red traffic light has the same meaning as a stop sign: you must come to a complete stop and proceed only when the way is clear.

A motorcycle is entitled to the full width of its lane; when passing, you must change lanes completely and give it the same space as you would a car.

Driving at an excessive speed reduces a driver's reaction time and dramatically increases the force of impact in a collision, raising the risk of serious injury or death.

If you accidentally take the wrong expressway exit, do not stop or reverse; continue to the next exit and use signs to find your way back to your intended route.

As you approach the crest of a hill, your visibility of the road ahead is limited, so you should reduce your speed and be prepared to stop for any hidden hazards.

The first sign indicating an upcoming highway-rail intersection is the round, yellow advance warning sign with a black "RXR" symbol.

This sign warns of a steep hill or downgrade ahead; be prepared to control your speed, possibly by shifting to a lower gear.

The distance it takes to stop a vehicle increases exponentially as its speed increases, due to both longer reaction time and braking distance.

The round yellow sign with a black "RXR" is the advance warning sign placed ahead of a highway-rail intersection to alert drivers.

Regulatory signs, which inform you of laws such as speed limits or parking rules, are typically vertical rectangles with black lettering on a white background.

If your wheels go off the pavement, you should grip the wheel firmly, ease off the accelerator, and brake gently before attempting to steer back onto the road.

This sign warns that the bridge ahead is narrower than the approaching road.

The shape of a route sign helps identify the type of road, such as an interstate (shield), U.S. highway (shield), or state highway (often a unique shape for the state).

Drivers intending to turn left must yield the right-of-way to any vehicles approaching from the opposite direction that are proceeding straight or turning right.

If you are confronted by an aggressive driver, the safest strategy is to avoid making eye contact, do not engage, and maintain a safe distance.

This sign indicates a center lane that is reserved for making left turns by traffic traveling in either direction.

At a yield sign, you must slow down and be prepared to stop, yielding the right-of-way to any traffic or pedestrians in or approaching the intersection.

To enter an interstate, use the on-ramp and acceleration lane to build up to the speed of traffic, signal, find a safe gap, and then merge into the travel lane.

Before entering an intersection, you should scan by looking left, then right, and then left again, as traffic from the left is the first you will encounter.

Relying only on mirrors is unsafe because all vehicles have blind spots—areas around the vehicle that cannot be seen in the mirrors.
