Iowa CAR DMV Practice Test 2

Dashed yellow lines separate single lanes of traffic moving in opposite directions. Passing is allowed when there is no oncoming traffic in the passing lane.

To slow down on a slippery road, you should first take your foot off the gas pedal. If you need to slow down even more, gently apply a slow, steady pressure to your brake pedal.

Under Iowa's Implied Consent Law, any peace officer may ask you to submit to a breath, urine, or blood test if the officer feels you may be driving under the influence of alcohol or drugs. This applies to both resident and non-resident drivers. If you take the test and fail, or you refuse to take the test, your license can be taken away on the spot.

At four-way stops, traffic from all four directions must stop. The first vehicle to reach the intersection should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.

Fog can greatly reduce your ability to see other vehicles, pedestrians, and traffic signals. When driving in fog, drive cautiously and at reduced speeds. Do not use high beam headlights. Low beams better illuminate the road and objects ahead in foggy conditions.

A distraction when driving is anything that takes your attention away from driving. Driver distractions may occur anytime and anywhere. Distracted driving can cause collisions, resulting in property damage, injury, and death.

An octagonal (eight-sided) sign always means "stop." You must always come to a complete stop at this sign.

If your vehicle begins to skid, do not use the brakes. Braking could make the skid worse.

If you are in an intersection when you see an emergency vehicle approaching while using its flashing lights and/or siren, continue through the intersection and then drive to the right and stop. You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren or flashing lights.

If you experience a sudden tire blowout, do not panic. Grasp the steering wheel firmly and take your foot off the accelerator to allow the vehicle to roll to a stop. Lightly apply the breaks when it is safe to do so. Do not move to the shoulder of the road until the car has slowed considerably.

This sign indicates that a divided highway begins ahead. The road splits into two one-way roadways separated by a median or divider. You must keep to the right.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

Pedestrians using guide dogs or white canes (with or without a red tip) must be given the right-of-way at all times.

When passing, you should not return to your original lane until you can see both headlights of the passed vehicle in your rearview mirror. Always check your blind spots before moving back into your original lane.

A solid yellow arrow means that the protection of a green arrow is ending. If you are turning in the direction of the arrow, you should prepare to stop and yield the right-of-way to oncoming traffic before turning.

An arrow painted on the pavement within a traffic lane indicates that drivers in the lane must make the movement indicated by the arrow. Drivers should follow directions given by any traffic signs or signals before proceeding in the direction indicated by the arrow.

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.

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.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow and black. This sign tells drivers that a lane is ending and that they should prepare to allow traffic to merge safely.

You must pull over to the right edge of the road and stop for an emergency vehicle with flashing lights, regardless of whether it is approaching you from behind or from the opposite direction.

If a tire suddenly goes flat while you are driving, hold the steering wheel tightly and keep the vehicle moving straight. Slow down gradually by taking your foot off the gas pedal and using the brakes lightly.

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

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

In snowy weather, keep your windshield and mirrors clear. Increase your following distance when driving in wet and cold weather because a slippery road surface will increase the distance needed for your vehicle to stop.

Children on bicycles are sometimes unpredictable. Young bicyclists are especially likely to make surprising changes in direction. Remember that children and bicycles are both small in stature and may become difficult to see.

Pentagonal signs mean you are approaching a school zone and/or school crossing. When you see these signs, be alert and prepare to stop.

Your vehicle's stopping distance increases as your speed increases. When driving at high speeds, it is important to look well ahead of your vehicle to allow yourself space to safely react to hazardous situations.

You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

A reflective orange triangle on the rear of a vehicle means it travels only at slow speeds. You may see this sign on roadwork equipment, farm vehicles, or horse-drawn wagons and carriages. It appears as a solid orange triangle during the day and a hollow red triangle at night.

If a tire blows out while you are driving, hold the steering wheel tightly and keep the car headed straight down the road. Ease your foot off the gas pedal and do not apply the brakes until you have complete control. When the car is under control, brake gently and pull off the road at the nearest safe location.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

You must yield to other drivers when entering a street from an alley, driveway, or garage. You must also yield to pedestrians who are on an intersecting sidewalk.

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.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.
