South Dakota CAR DMV Practice Test 19

If you want to enter the freeway but do not see a space for your vehicle in traffic, slow down on the ramp to wait for a gap. Do not drive to the end of the ramp and wait for a gap or you will not have enough room to accelerate to the speed of traffic before entering the roadway.

You should avoid looking toward the bright lights of an oncoming vehicle by glancing toward the right side of the road. After looking briefly toward the side of the road, continue looking ahead to check on the position of the other vehicle.

When driving a vehicle equipped with an Anti-Lock Braking System (ABS), a driver should press the brake pedal firmly when stopping on a snowy or icy surface. The ABS will pump the brakes more rapidly than a driver would be able to.

Crosswalks exist whether the lines are marked or unmarked. You must stop behind a crosswalk to allow any pedestrians to cross.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

If you are already within an intersection when the traffic light turns yellow, you should clear the intersection as quickly as possible.

Blind spots are areas that a driver cannot see if they look in their mirrors. Large trucks have large blind spots that drivers of other vehicles should avoid.

You should drive more slowly at night than during the day because it is not possible to see as far ahead at night. You should make sure that you can stop within the area illuminated by your headlights.

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.

Drivers should signal when pulling next to a curb or away from a curb.

This sign indicates that you may not make a U-turn. You cannot turn around to go in the opposite direction at an intersection where this sign is posted.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

As daylight begins to fade, turn on your low beams to help others see you. Only use your high beam headlights in an open area where no other drivers are present.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

This sign indicates that you are approaching a railroad crossing. You must look, listen, slow down, and prepare to stop. Wait for any trains to pass before you proceed.

Warning signs are usually yellow with black markings. This sign indicates that a divided highway is beginning and cars should keep to the right.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

Bring your vehicle to a complete stop at a crosswalk to yield the right-of-way to any vehicle or pedestrian already in the intersection. You may carefully proceed if your lane is completely clear.

Make sure there are no loose objects in your vehicle that could hit and injure someone in the event of a sudden stop or crash. Make sure there are no objects on the floor that could roll under the brake pedal and prevent you from stopping the vehicle.

White lines separate lanes of traffic moving in the same direction. You may cross a dashed white line to pass or change lanes if it is safe to do so.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

There are many areas where you cannot park. You should not park within 15 feet of a fire hydrant.

A flashing red traffic light means the same thing as a stop sign. When arriving at an intersection with a flashing red light, you must come to a full stop and proceed when it is safe to do so.
