Wisconsin CAR DMV Practice Test 17

A double yellow centerline means that it is prohibited for traffic from either direction to cross the centerline to pass.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

If a vehicle approaching you is using its high beams and fails to dim them, you should glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see well enough to stay on your course until the vehicle passes.

If a yellow panel with the message "Exit only" is on a highway sign, the lane below the sign will not continue through the interchange. Instead, the lane will go off of the roadway to form a ramp. If you are in a lane directly under an "Exit only" sign, you may change lanes to move through the interchange or you must exit the highway.

Any eight-sided sign is a stop sign. At an intersection with a stop sign, you must stop completely and check for pedestrians and cross traffic in the intersection. Wait for the intersection to clear before proceeding.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

Wisconsin law requires that the driver and all passengers wear seat belts while in a moving vehicle.

White lines are used to separate traffic moving in the same direction. Solid lines indicate that drivers are not permitted to pass.

Large vehicles can cause wind gusts with a force great enough to cause direction changes in smaller vehicles. Drivers of small vehicles should be prepared to take proper corrective steering action when approaching or passing large vehicles that are moving at or near maximum speeds.

Warning signs are usually yellow with black markings. These signs alert drivers to areas where bicycles may be crossing.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This sign tells drivers the direction in which they must drive when turning onto a one-way street.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

If another driver is threatening you or intentionally driving dangerously around you, remain calm and try to put as much distance between the two of you as possible. Slow down and let them pass. Do not make eye contact and do not make obscene gestures.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

If you are on an entrance or acceleration ramp and are entering interstate traffic, you should yield to drivers already on the interstate highway. Merge safely into traffic when you are able to do so.

When parking facing uphill on a street that has a curb, set your parking brake and turn your steering wheel away from the curb. This way, if your vehicle starts to roll, it will roll into the curb.

This sign provides advance warning that bicycles may be present.

A broken yellow centerline means that a driver may cross the centerline to pass another vehicle on the left as long as there is no oncoming traffic. Drivers should never cross a solid yellow centerline in order to pass.

This sign indicates that the road ahead changes direction at an extreme angle (in this case, to the right). Before you reach such an extreme curve, you should slow down as much as you would when making a turn at an intersection.

When there is a solid yellow line and a broken yellow line in the center of the road, passing is permitted from the side of the road next to the broken line.

Flashing red lights are used at dangerous intersections. Treat them like stop signs.

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

If you are entering traffic from a driveway or private road, you should yield to drivers already on the public road. Merge safely into traffic when you are able to do so.

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.

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.

Construction, maintenance, and emergency operations signs are generally orange with black symbols.

If your vehicle breaks down on a highway, make sure other drivers can see it. Get your vehicle off the road and away from traffic if at all possible and turn on your emergency flashers to show that you are having trouble.

Pavement on bridges and overpasses can become icy even when other surrounding pavement is dry. Bridges often freeze before, and thaw out after, the rest of a road.
