Massachusetts CAR DMV Practice Test 22

Because a large vehicle, such as a truck or bus, has large blind spots to its sides and rear, avoid driving alongside such a vehicle and do not tailgate one.

When passing, you must always signal at least 100 feet in advance of your lane change. Always check behind you in your mirrors and look over your shoulder to check your blind spot. Wait until you can see both headlights of the passed car in your rearview mirror before returning to your original lane.

Unless posted otherwise, your speed is not reasonable and proper if you drive at speeds faster than 50 mph on highways outside of thickly settled areas or business districts.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. Right turns are not permitted where this sign is posted.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers to be extra careful when the pavement is wet because the road may become slippery, making vehicles more difficult to control.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

A triangular red and white yield sign means that you must decrease speed as you approach an intersection and yield the right-of-way to any vehicles or pedestrians in the intersection. You must be prepared to stop if conditions require it.

If you encounter an aggressive driver, you should make every attempt to get out of their way. You should avoid making eye contact with a hostile driver. Challenging a hostile driver by speeding up may only make them angrier, thereby increasing their danger.

Crosswalk lines show pedestrians where to safely cross a road or street. Crosswalks may be marked by horizontal lines, vertical lines, or a combination of the two. You must always stop for pedestrians who are in a crosswalk.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be cautious when driving under conditions that may cause the roadway to become wet and slippery.

This sign indicates that there is a flagger ahead controlling traffic in a construction area.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

This sign marks parking spaces that are reserved for people with disabled parking permits.

You cannot pass safely when driving on a two-way, two-lane street unless you can clearly see the road ahead, you can return to your lane before meeting oncoming traffic, and your vehicle is capable of the speed necessary to pass. Do not pass where it is illegal and unsafe to do so.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

Lane usage for the motorcyclist is critical. Motorcycles are entitled to the same full lane width as all other vehicles.

Factors that can affect braking distance include how fast your vehicle is traveling, the condition of your brakes and tires, and the condition of the pavement.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

A flashing yellow light warns of a hazard. Slow down and proceed with caution.

When approaching an unmarked railroad crossing, slow down and be prepared to stop. Before you cross, be sure that no trains are approaching from either direction on any track. If you see or hear a train coming, stop at a safe distance from the nearest track and wait to proceed until after the train passes.
