Iowa CAR DMV Practice Test 24

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.

Before returning to your original lane after passing, you must make sure you are not dangerously close to the vehicle you have just passed. When you can see both of the vehicle's headlights in your rearview mirror, you may have enough room to return to the lane.

It is always unlawful to exceed the posted speed limit, even when passing another vehicle.

As speed increases, the chance of a fatality increases. If you are moving faster than 80 miles per hour, you have almost no chance of living through a crash. Driving more slowly than other traffic can also be dangerous because other motorists may become impatient and make dangerous moves to pass you.

When approaching a school bus that is using its flashing red lights, you must stop before you reach the bus and remain stopped until the flashing lights are turned off. On a two-way multilane roadway with a median or shared center lane, vehicles on the opposite side of the road from the school bus do not have to stop.

After an accident, do not move the injured unnecessarily. Unskilled handling can make serious injuries out of minor ones. Keep the injured warm until skilled help arrives. If there is severe bleeding, attempt to stop the flow of blood with direct pressure.

If you miss your turn or exit, do not back up in the travel lane or on the shoulder. Continue to drive to the next exit or crossroad. Drivers do not expect a vehicle to be backing toward them on the roadway and doing so will likely cause a collision.

Many over-the-counter medications can affect your ability to drive safely. If you take medication, even a remedy for colds or allergies that is not prescribed, check the label for warnings about its effects. If you are unsure, ask your doctor or pharmacist about driving while on the medication.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

A flashing red traffic light means the same thing as a stop sign. You must come to a complete stop, yield to other traffic and pedestrians, and then proceed when it safe to do so.

You may not stop, stand, or park at a red-painted curb.

Pedestrians should not enter a street or crosswalk when vehicles are approaching. Though pedestrians have the right-of-way in crosswalks, a vehicle approaching from a close distance may not have the time to stop before entering the crosswalk.

Warning signs alert drivers to upcoming hazards and are usually yellow with black markings. This sign warns drivers about potential traffic merging into their lane from the right.

Regulatory signs are often rectangular and white with black markings and are used to indicate what things a driver must or must not do in a designated area. They may display speed limits, prohibit passing or turning, or clarify any other driving regulation.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about the presence of traffic signals at an intersection ahead.

Your vehicle's blind spots are the areas that you cannot see in your mirrors. Look over the appropriate shoulder to check your blind spot when changing lanes.

You must not drive at a speed that is faster than is reasonable and prudent. You must drive at a speed that is appropriate for the area where you are driving, the type and condition of surrounding traffic, the presence of pedestrians, the weather, the quality of the road, and light conditions. You must drive within legal speed limits.

Safe use of the interstate demands drivers be constantly alert and capable of driving at high speeds.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

Your suspension helps you control your vehicle and provides a comfortable ride over varying road surfaces. If your vehicle bounces a lot after driving over a bump, or is generally hard to control, you may need new suspension parts.

Night driving creates a unique set of problems for drivers. Due to the reduced visibility, it can be difficult to judge distance and the traveling speeds of other vehicles when driving at night. Drivers can see only as far as their headlights allow.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

A flashing yellow light warns of a hazard. Slow down and proceed with caution.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Just before you begin moving into the other lane, quickly glance over your shoulder and check for any vehicles that may be in your blind spot.

If two vehicles arrive at the same time to an intersection that has stop signs on all corners, the vehicle to the right has the right-of-way.

Compared to signs and other roadside objects, pedestrians are hardest to see at night.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

A flashing yellow traffic light means drivers must slow down, be more aware, and proceed with caution. Be alert to crossing traffic and pedestrians.

Driving can become unsafe if drivers believe they have nothing to improve. For your safety and the safety of others, always strive to improve your driving and observation skills.

Every time you have to stop quickly, it takes time and fuel to accelerate and get your vehicle back up to the speed of traffic. Drivers who look far ahead of their vehicles can slow down gradually or change lanes to avoid unnecessary braking, leading to better gas mileage.

Before you enter an intersection, look to both the left and right for approaching vehicles or crossing pedestrians. Look to your left a second time, as vehicle approaching from your left will be closer than those approaching from your right. Look across the intersection before you start to move to make sure the path is clear all the way through.

Stop at a railroad crossing when the warning lights start to flash and the gate lowers. Remain stopped until the gate is raised and the lights stop flashing. Never drive around lowered gates at a railroad crossing because it is against the law and very dangerous.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

The most important thing to remember about driving in curves is that your vehicle’s inertia may make it difficult to turn. To maintain control, it is essential that you slow down before entering the curve.
