Massachusetts CAR DMV Practice Test 23

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

If an approaching driver fails to dim their high beams, 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 enough of the road to stay on course until the other vehicle has passed.

This sign indicates that a steep downhill grade is ahead.

High speeds greatly increase stopping distances and severity of crashes. The faster you drive, the greater the impact or striking power of your vehicle, should you be involved in a collision.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

A truck or bus has blind spots on each side, in the rear, and in the front. An automobile cannot be seen in these blind spots. These blind spots are referred to as the “No zone.”

If the weather changes suddenly, you will need to adjust your driving to adapt. Always slow down when driving in rainy or foggy conditions. Be especially aware of vehicles behind you that may be going too fast for conditions.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

Special child seats are available for children who are too small to wear regular safety belts. No person is strong enough to safely hold onto a child of any size during an accident or sudden stop. Never allow a child to ride in a vehicle unless they are properly fastened into a seat.

Crossbuck signs tell drivers to yield to trains at a railroad crossing. Drivers should not try to outdrive a train.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

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.

Look over your shoulder to check your blind spot every time you want to change your vehicle's position. If you are turning, changing lanes, or pulling toward or away from a curb, you should check your blind spots.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

Work zone signs are orange and indicate that some type of work is being performed on or alongside the roadway. Be extremely careful when you see these signs.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.

Bicycles on the road are considered vehicles and have the same rights and responsibilities as motor vehicles. Drivers of motor vehicles should respect the rights of bicyclists.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

You should increase your following distance when you are behind a large vehicle that blocks your vision, when driving in bad weather or heavy traffic, when exiting an expressway, when behind a motorcycle or bicycle, and if someone is tailgating you.

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 one-way sign indicates that traffic flows only in the direction of the arrow.

A green light tells you that you can go through the intersection. However, you must first yield the right-of-way to traffic and pedestrians who are still in the intersection.

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.
