Maryland CAR DMV Practice Test 18

As you enter a work zone, signs and message boards will warn you of workers, slow-moving equipment, and/or closed lanes ahead. You should reduce your speed and be prepared to slow down or stop.

Use your right foot for both braking and accelerating. You should apply the brakes gently with increasing pressure so that your vehicle stops gradually and smoothly.

Drivers should signal when pulling next to a curb or away from a curb.

Remember that all medications, prescription or over-the-counter, are potentially dangerous and could impair your driving. Over-the-counter medicines that you take for colds and allergies can make you drowsy and affect your driving ability. It is your responsibility to know how your medication affects your ability to drive.

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

Never assume other drivers will give you the right-of-way. Yield your right-of-way whenever it helps prevent collisions.

To stay aware of hazards, you should scan the road and check your rearview mirrors every two to five seconds. Constantly staring at just the road ahead of you is dangerous. If you must drive in foggy conditions, you should use your low beam headlights, not your high beam headlights.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. If you are making a left turn from a one-way street, this means that you would make the turn from the lane nearest to the left curb.

You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit. Some conditions which require reduced speed for safety include approaching curves or hills where visibility is limited, driving on slippery roads, and driving on roads where animals and pedestrians are present.

Warning signs are usually yellow with black markings. This sign warns drivers about an upcoming steep hill. Drivers should slow down and be ready to control their speed and protect their brakes from damage.

Drivers turning left must yield to oncoming vehicles that are driving straight ahead. A turning driver may only proceed when they can safely turn without affecting oncoming traffic.

This sign warns that a steep downgrade is ahead on the road. Drivers should check their brakes.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must always yield the right-of-way to a pedestrian who is using a guide dog or carrying a white cane.

You must have evidence of financial responsibility, such as proof of insurance, with you whenever you drive. You must always show proof of insurance and your license to an officer upon request after a traffic stop or collision.

Work zones on highways have become increasingly dangerous places for both workers and drivers. When approaching a work zone, watch for materials such as cones, barrels, signs, large vehicles, and workers in brightly colored vests to warn you and direct you.

If your vehicle enters a skid, you should take your foot off of the brake and steer in the direction that you want to go. For example, if the rear of your vehicle is skidding to the left, you should steer to the left. This will help bring the front of the vehicle in line with the rear, thereby straightening out the vehicle's overall direction.

Driving too slowly can be dangerous because it may cause drivers behind you to become frustrated and make dangerous moves to pass you. It is safest to drive with the flow of traffic, within the legal speed limit.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

Hydroplaning occurs when there is standing water on a roadway. At speeds up to 35 mph, most tires will channel water away from the tire. As your speed increases past 35 mph, tires cannot channel the water as well and your tires may start to lose contact with the road and ride over the water like a set of water skis.

You must never turn around while on or near any curve or hill. You may not be able to see oncoming traffic or pedestrians and may cause a collision.

This sign prohibits right turns. You cannot make a right turn at an intersection where this sign is posted.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that another road crosses the highway ahead.

Alcohol and other drugs can negatively effect a number of skills needed for safe driving, including a driver's reaction time, coordination, alertness, and ability to concentrate.

When leaving an interstate, you should maintain your speed until you enter the deceleration lane, at which point you should reduce your speed to the exit ramp's posted advisory speed.

Your vehicle's stopping distance increases as your speed increases. When driving at high speeds, it is important to look well ahead of your vehicle to allow yourself space to safely react to hazardous situations.
