Iowa CAR DMV Practice Test 4

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

When driving near a blind pedestrian, using your horn may be dangerous. Yield to the pedestrian and proceed when it is safe to do so.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

Before you return to your driving lane, be sure you are not dangerously close to the vehicle you have just passed. One way to do this is to look for the vehicle in your inside rearview mirror. When you can see both headlights in your rearview mirror, you may have enough room to return to your driving lane.

Being under the influence of alcohol affects your judgment. Good judgement is necessary to react appropriately to things that you see or hear while on the road. Even if you are below the legal blood alcohol limit, consuming any amount of alcohol is likely to affect your ability to drive safely.

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

You must always stop before crossing railroad tracks if flashing red lights are activated, a crossing gate is lowered, a stop sign is posted, a flagger signals you to stop, or a train is visible or so close to the crossing that it would be hazardous to continue driving. If you are unsure if a train is too close for you to safely cross the tracks, stop. Never race a train.

Drivers are responsible for making sure their vehicles do not become hazards after they have been parked. Wherever you park, make sure your car is visible to drivers approaching from any direction.

Try to avoid panic stops by watching well ahead of your vehicle for hazards. If you allow yourself space to react to hazards, you are less likely to need to stop or turn suddenly.

Signs with a red circle and diagonal line over a black symbol indicate the the action represented by the symbol is prohibited. In this case, the sign indicates that right turns are prohibited.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

Yellow lines are used to separate traffic moving in opposite directions. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

This sign indicates that the road ahead becomes a divided highway. Keep to the right of the divider or median.

When turning, you should look to the rear and both sides of your vehicle to ensure it is safe to proceed before making the turn. Adjust your speed to safely complete the turn.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.

When driving in fog, you should slow down and use your low beam headlights. If the fog is so bad that you cannot see, pull off the road and wait for the fog to clear.

Traffic signs with three sides of equal length warn drivers to slow down when approaching an intersection and to be prepared to come to a complete stop to yield to other drivers or pedestrians. Drivers may proceed when it is safe to do so.

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

All temporary signs in work zones have orange backgrounds with black writing and/or symbols.

Orange is the standard color for work zone activity. If you see orange signs, cones, or barrels while driving, stay alert and be prepared for unexpected driving conditions. This sign alerts drivers to an upcoming flagger whose directions should be obeyed by all drivers.

A green arrow displayed on a traffic signal tells drivers that they may turn in the direction of the arrow. You must be in the proper lane for such a turn. Yield the right-of-way to vehicles and pedestrians already in the intersection.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. These signs may be accompanied by speed advisory plaques that indicate the speed with which you should proceed.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.

Factors affecting a person's absorption of alcohol include the person's weight, their biological sex, the amount of food in their digestive tract, and the number of alcoholic beverages they have consumed. The only thing to do to remove alcohol from a person's system is to wait.

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.

This triangular sign is a "Yield" sign. When you see this sign, you must slow down to check for traffic and yield the right-of-way to pedestrians and approaching cross traffic. Stop only if it is necessary to do so.

The distance required to stop your vehicle depends on perception time, reaction distance, and braking distance. This changes with speed and road conditions.

This sign indicates parking spaces that are reserved for vehicles displaying Persons with Disabilities license plates, Disabled Veteran license plates, and/or disabled parking placards.

Do not pass unless you have enough space to return to the driving lane. Before you return to the driving lane, be sure you have enough room between yourself and the vehicle you have passed. When you can see both headlights of the passed vehicle in your rearview mirror, it is safe to return to the driving lane.

When traffic control signals are not working, a driver must always treat the intersection as an all-way stop and come to a complete stop, unless otherwise directed by law enforcement. The driver must then look and yield the right-of-way before entering the intersection.

Use high beam headlights only when driving in rural areas and when other cars are not nearby. Lower your headlights to their low beam setting when you are following closely behind another driver.
