Massachusetts CAR DMV Practice Test 19

This sign indicates that an intersection with a crossing road is ahead.

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 "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

You drive defensively when you identify dangerous driving situations and take action before an accident occurs. Defensive driving helps prevent conflicts with aggressive, offensive, discourteous, careless, inattentive, impulsive, ignorant, or intoxicated drivers or pedestrians.

If you drink alcohol, even just one drink, your chances of being in a crash are much greater than if you did not drink any alcohol. No one can drink alcohol and drive safely, even if you have been driving for many years.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

Situations where motorists are required to stop include approaching intersections with stop signs, approaching intersections where a red light is either flashing or illuminated, or any time when a traffic officer orders your vehicle to stop.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that parking is not permitted.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

When approaching a stopped school bus that is using its stop signal, a driver is required to come to a complete stop. They should not proceed until the stop arm is withdrawn.

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

Smoking while driving can create dangerous distractions by causing you to take your hands off the wheel and/or your eyes off the road.

Stopping distances increase on wet or icy roads. Stopping distances also increase on road surfaces covered in loose gravel or stones.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they are approaching an area with low clearance.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that right turns are prohibited.

This sign indicates the presence of a pedestrian crossing. Drivers should be cautious when driving where pedestrians may be present.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before 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.

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.

A flashing red light means the same thing as a stop sign. If you encounter a flashing red light, you should come to a complete stop, yield to appropriate traffic and pedestrians, and only proceed when it is safe to do so.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

This sign marks a high occupancy vehicle (HOV) lane. HOV lanes are reserved for use by buses and vehicles with a driver and one or more passengers, as indicated on the sign.
