Connecticut CAR DMV Practice Test 17

A triangular yellow sign with black lettering indicates a no passing zone. It will appear on the left side of a two-way, two-lane roadway at the beginning of an area where prohibitive pavement markings are also used.

If you are in an intersection when you see an emergency vehicle approaching while using its flashing lights and/or siren, continue through the intersection and then drive to the right and stop. You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren or flashing lights.

Diamond-shaped signs are used to warn of actual or possible hazards. The color orange is used for warning signs usually found in construction or maintenance areas.

Blood alcohol concentration (BAC) is a measurement of the percentage of alcohol in the blood. The higher the BAC number, the more impaired a person is.

When entering and driving through a work zone, slow down and be prepared to stop. Obey posted speed limits and be alert to conditions around you. Workers could be present.

When you follow so closely behind a truck that you cannot see the truck driver’s side view mirrors, the trucker cannot see you and has no way of knowing you are there. Tailgating a truck, or any vehicle, is dangerous because you take away your own cushion of safety if the vehicle in front of you stops quickly.

When being tailgated, create extra space in front of your vehicle and do not brake suddenly. Slow down gradually or merge into another lane to prevent a collision with the tailgater.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

If two vehicles arrive at the same time to an intersection that has stop signs on all corners, the vehicle to the right has the right-of-way.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers to be careful when driving under wet conditions as the pavement will become slippery and more difficult to navigate safely.

This sign indicates that there is a yield sign ahead. You should begin to slow down when you see this warning sign.

The term “distracted driving” refers to driving while anything takes your eyes, hands, or mind away from the task at hand. Distracted driving is the most common contributing factor to reported traffic collisions. Distractions of any sort cause drivers to miss key visual and audio cues needed to avoid a crash.

You should avoid looking toward the bright lights of an oncoming vehicle by glancing toward the right side of the road. After looking briefly toward the side of the road, continue looking ahead to check on the position of the other vehicle.

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

Warning signs are usually yellow with black markings. This sign indicates that there could be traffic merging from the right, so drivers should prepare to allow traffic to safely merge.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

A round yellow sign indicates that there is a railroad crossing ahead.

An octagonal (eight-sided) sign always means "stop." You must always come to a complete stop at this sign.

A double yellow centerline means that it is prohibited for traffic from either direction to cross the centerline to pass.

This sign indicates that there is a crossroad ahead.

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.

A flashing yellow light means that you should slow down, check for cross traffic, and proceed with caution.

Children are often the least predictable pedestrians and the most difficult pedestrians to see. Take extra care to look out for children, especially near schools, bus stops, playgrounds, parks, and ice cream trucks. Be aware of children riding bikes on the sidewalk, as they may come onto the road unexpectedly.
