Iowa CAR DMV Practice Test 5

Yellow lines are used to divide traffic moving in opposite directions.

On slippery roads, you should increase your following distance. It may take more time to stop your vehicle than it would under normal conditions.

You must yield the right-of-way to any emergency vehicle that is using its siren and flashing lights. Do this by driving to the right edge of the road and stopping, taking care not to stop in an intersection. You may move again after the emergency vehicle has passed.

A three-sided yield sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. In this case, you do not have the right-of-way.

Decrease your speed as you approach an intersection with a yield sign. Prepare to stop and yield the right-of-way to vehicles and pedestrians in the intersection or crossroad. You must come to a full stop at a yield sign if traffic conditions require it.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

If an emergency vehicle with flashing lights is traveling in the area where you are driving, you must make every effort to give them a clear path of travel. If it is safe to do so, pull your vehicle to the side of the road to give the emergency vehicle an open pathway.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

When parking on an incline where there is a curb, you should turn your wheels sharply to the left, away from the curb. This way, if your brakes fail, your vehicle will not roll into traffic.

This sign warns of the presence of a crossroad ahead.

A round sign always indicates that you are approaching a railroad crossing.

A flashing yellow traffic light means drivers should slow down and proceed with caution.

If your vehicle begins to skid, remain calm. Steer in the direction that you want to go and try not to overcorrect.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

When passing, you should not return to your original lane until the entire vehicle you've just passed is visible in your rearview mirror.

A steady yellow light indicates that a steady red light will soon appear. If you are driving toward an intersection and a yellow light appears, slow down and prepare to stop. If you are already within the intersection or cannot stop safely before entering the intersection, continue through carefully.

You should avoid passing other vehicles on two-lane roads. Every time you pass a vehicle, your odds of being in a collision increase.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

A diamond-shaped yellow sign warns of possible danger ahead. Orange signs, which are mostly diamond-shaped, are used to warn of possible dangers in or near work areas.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.

Your tires do not have as much traction on loose gravel and dirt roads as they do on concrete and asphalt roads. When driving on gravel or dirt, you must slow down. It will take you much longer to stop and it is much easier to skid when turning.

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

When broken yellow lines separate the lanes of traffic on a two-lane roadway, any driver may pass when there is no oncoming traffic.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that there is an upcoming sharp turn and that they should lower their speed accordingly.

This sign warns that the road is slippery when wet.

You should not use cruise control on snow, in rain, in fog, or under similar hazardous conditions. Winter is the most difficult driving season and requires extra caution from drivers. It is important to consistently check your antifreeze and windshield washer fluid levels. Using snow tires can increase a vehicle's traction on the surface of slippery roads.

A double solid yellow line means that it is prohibited for vehicles traveling in either direction to cross the centerline to pass.

At a four-way stop, you must yield the right-of-way to drivers who arrived before you. Wait your turn to enter the intersection.

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

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Situations where motorists are required to stop include approaching intersections with stop signs, approaching intersections where a red light is either flashing or illuminated, or any time when a traffic officer orders your vehicle to stop.

This sign indicates that a roundabout is ahead. Enter a roundabout at a low speed and yield to existing traffic.

Slow down and proceed with caution if you see animals that are standing near the roadway. They may unexpectedly bolt or change direction at the last moment. Some animals travel in packs, so there may be more animals just out of sight that are also near the road.
