Massachusetts CAR DMV Practice Test 11

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

High beam headlights normally let you see about 350 feet ahead. Use your high beam headlights when driving in dark areas where you cannot see the road surface ahead. You must lower your high beam headlights to low beams when you are within 500 feet of an oncoming vehicle or within 200 feet of a vehicle traveling ahead of you.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

A flashing yellow arrow indicates that left turns are allowed in the direction of the arrow. However, the oncoming traffic has a green light and you must yield to oncoming traffic and pedestrians.

This sign warns that the road is slippery when wet.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.

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.

To keep your vehicle from rolling into traffic when parked facing uphill, turn your front wheels sharply away from the curb. If you are parking uphill on a street that has no curb, turn the wheels sharply toward the edge of the road.

If a driver's left arm and hand are extended downward, they are indicating that they intend to stop. Adjust your driving accordingly if following a driver who is using this hand signal.

Any time you want to change lanes, you should properly signal your intentions well in advance, check your mirrors, and check your blind spot. You can check your blind spot by glancing over your shoulder in the direction that you plan to move.

When changing lanes, it is important to check your blind spots. Do this by looking over your shoulder toward the next lane. Do not rely only on your mirrors.

This sign indicates that the road ahead turns sharply to the right and then sharply to the left.

When driving on wet roads, drivers should increase their following distance.

There is no quick way to sober up or to get the alcohol out of your body. Drinking black coffee, taking a cold shower, exercising, or eating might make you feel more alert after drinking alcohol. However, none of these actions affect how quickly alcohol leaves your body.

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.

Your horn should be used as a warning in situations where you think another driver or a pedestrian does not see you. For example, if a child begins to run into the street in front of your vehicle, you should sound your horn.

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.

Always stop before entering the roadway from a driveway and yield to any approaching vehicles or crossing pedestrians. The stop should be made before crossing the sidewalk area. Failure to stop is unlawful.

A Pedestrian Hybrid Beacon (PHB) allows pedestrians to safely cross a roadway. A PHB only operates when activated by a pedestrian. When the PHB is displaying two flashing red lights, you must come to a complete stop before proceeding with caution.

This signs warns that a four-way intersection is ahead.

When passing a vehicle that has just parked parallel to the road, you should assume the driver will open the door as you approach. Use extra caution when driving near parked vehicles.

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.

Always slow down near a curve or in any area where you cannot see clearly ahead. Reduce your speed before you enter a curve in the road so you do not have to brake in the curve. Braking in a curve can cause a skid.

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

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.
