Massachusetts CAR DMV Practice Test 21

A "No standing" sign means that you may only make a temporary stop to load or discharge passengers.

Your tires become less effective at clearing water from the road as you increase your speed. If you drive too fast, they may lose their grip entirely, leaving the vehicle sliding on a film of water. This is known as "hydroplaning."

A red traffic light means that you must stop before entering the intersection. You must at any stop line and before entering any crosswalk.

This sign warns that especially slippery conditions exist when the road is wet.

Distractions cause drivers to react more slowly to traffic and hazards on the roadway. Distracted driving is never safe.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

When you park on a downward-facing slope, turn your wheels sharply toward the side of the road. This way, if your vehicle starts to roll downhill, it will roll away from traffic.

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

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.

When you see an emergency vehicle using its lights or hear it using its siren, you must immediately pull over to the curb or side of the road and stop.

When approaching an intersection with a solid yellow traffic light, slow to a stop before entering the intersection, if it is safe to do so. If you can't stop safely, drive carefully through the intersection.

If you are driving a motor vehicle in Massachusetts, you have given your consent to a test to determine the alcoholic content of your blood and the presence of any abused or illegal controlled dangerous substance. If you refuse to submit to the test, your driving privileges will be suspended.

Don’t make a last-minute turn into an exit. If you pass your exit, you must go to the next one.

On a traffic signal arranged vertically, red is always on top and green on the bottom. When arranged horizontally, red is always on the left and green on the right.

In rainy conditions, you should use your low beam headlights.

A steady yellow light indicates that a steady red light will soon appear. If you are driving toward an intersection and a yellow light appears, slow down and prepare to stop. If you are already within the intersection or cannot stop safely before entering the intersection, continue through carefully.

If you are being followed by an emergency vehicle that is not using its siren or flashing lights, you do not need to clear a path. Continue driving in a normal manner.

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.

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

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.

A yield sign means that you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.

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

This sign warns that there is a steep hill ahead.

When turning, you should reduce to a speed that allows you to maintain control of your vehicle, stay in your lane, and react to unexpected situations.

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.
