Massachusetts CAR DMV Practice Test 24

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.

This sign is placed at the beginning of one-way streets and ramps to indicate that you must not continue driving in your current direction.

This sign indicates that the road ahead curves to the right.

Reducing your speed should be your first response to decreased visibility and dangerous road conditions.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

This sign indicates that there is an intersection ahead. A road joins from the right.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

There are a number of locations where it is unlawful to park, including on a crosswalk or in a marked bicycle lane. When parking on the street, you must be within 12 inches of the side of the road.

While it is always dangerous to drive too fast on slippery roads, this is especially true when driving in turns and curves. Be sure to approach them more slowly in slippery conditions than you would under normal circumstances.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

If you experience a tire blowout, do not immediately apply the brakes. Grip the steering wheel firmly and steer to remain in your traffic lane. Reduce your speed gradually by releasing the accelerator and staying off the brakes. Once you are moving very slowly, apply the brakes lightly and pull off the road into a safe area.

When making a left turn where there is approaching traffic, you must wait for the approaching traffic to go through before you turn. You may enter the intersection to prepare for your left turn if the light is green and no other vehicle ahead of you plans to make a left turn.

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming intersection.

If you hear a siren or an air horn close by but do not know exactly where the emergency vehicle is, safely pull over to the right side of the road and stop until you are sure it is not headed toward you.

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

Your turn signals should always be used when you make any movement to the left or right. You should use your signal when pulling into traffic from a curbside parking space, moving into a new lane, or passing another vehicle.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

You should never start a left turn until you can see that all the lanes you need to cross are clear and that you can safely make the turn.

Chevron signs like this indicate that the road curves sharply in the direction indicated by the chevron (in this case, to the left). There may be several chevron signs placed throughout a curve.

Yellow centerlines are used to separate traffic moving in opposite directions. Broken lines may be crossed to pass slower-moving traffic when it is safe to do so.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

Regulatory signs are often rectangular and white with black markings and are used to indicate what things a driver must or must not do in a designated area. They may display speed limits, prohibit passing or turning, or clarify any other driving regulation.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.
