Texas CAR DMV Practice Test 17

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential bicycle cross traffic.

Drowsiness or unawareness can be brought on by reduced activity and the steady sounds of the wind, engine, and tire hum. This is known as "Highway hypnosis." Highway hypnosis can be combated by drivers continuing to move their eyes while driving and by stopping to stretch every 100 miles, even if they don't feel tired. To be safe, drivers should only drive for a maximum of eight hours in one day.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. Eating before or while you drink helps slow the absorption of alcohol somewhat, but it cannot prevent intoxication or impairment if you have too much to drink.

A flashing red traffic light has the same meaning as a stop sign. You must stop, yield the right-of-way, and go once it is safe.

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.

If using a hand signal, hold the signal until you are close enough to the intersection for others to know your intention. Do not hold the signal while making the turn. You need both hands on the wheel.

If you are stopped by law enforcement, you should park your vehicle as far to the right side of the road as possible. If available, park on the right shoulder or park on a nearby well-lighted side street or parking lot away from high-volume traffic.

You may cross a single broken line to pass or change lanes as long as you can do so safely and without interfering with traffic.

If oncoming drivers do not dim their headlights for you, keep your eyes on the right side of the road ahead. Do not look directly at the oncoming headlights because the glare may blind you for several seconds.

When driving to an unfamiliar area, plan your trip in advance. Don’t start with only a hazy idea of where you are going. If your destination is in an unfamiliar area, check the location on a map before you start to drive.

The only time a vehicle should enter the center lane is at a point where the vehicle will have time to slow down or stop in order to make a safe left turn maneuver. The center lane should never be used as a passing lane or as a through-traffic lane.

If you are operating a motor vehicle involved in a crash resulting in injury to or death of a person, you must immediately stop your vehicle at the scene of the crash without obstructing traffic more than necessary. If you did not stop your vehicle at the scene, you must immediately return and remain at the scene of the crash.

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.

Shared lanes are intended for use by bicyclists. They assist bicyclists with lateral position in lanes too narrow for a motor vehicle and a bicycle to travel side by side within the same traffic lane. Shared lanes also alert road users to the location bicyclists are likely to occupy.

Convictions for some offenses result in the automatic suspension of your license and driving privilege. These offenses include driving while intoxicated, failing to stop and render aid following a collision, and driving with an invalid license.

This sign indicates that there is a sharp right turn ahead.

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

Crashes often occur when one driver does not see another vehicle or when a driver does something unexpected. Communicate with other drivers on the road to help prevent traffic crashes.

A steady yellow traffic light indicates that the light will soon change to red. You should be prepared to stop for the red light, if it is safe to do so.

Street racing, also known as drag racing, is illegal and can result in serious injuries or fatalities. Due to the high speeds, drivers are unable to react to common road hazards and other driving situations, often resulting in crashes.

Even the most experienced drivers can be distracted while driving. A defensive driver looks out for the actions of other drivers and anticipates potential problems.

This sign indicates that there is a traffic signal at the intersection ahead.

As your speed increases, your field of vision decreases. When driving 60 mph, your field of vision is reduced to one-fifth of what your field of vision is when your vehicle is stationary.

If your vehicle’s right wheels leave the pavement, don't panic. Take your foot off the accelerator and steer parallel to the road. Slow down and ease back onto the roadway by keeping both hands on the steering wheel and steering into the road’s right lane with a small turn of the steering wheel. Check for traffic around you before steering back onto the pavement.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

If a driver's left arm and hand are extended downward, they are indicating that they intend to stop. Adjust your driving accordingly if following a driver who is using this hand signal.

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 even a small amount of alcohol will impair your vision, judgment, concentration, and coordination.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. It is not affected by the type of alcoholic beverages you drink, your level of physical fitness, or how well you can "hold your liquor."

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.
