District Of Columbia CAR DMV Practice Test 2

It is illegal to drive under the influence of any substance that impairs your ability to drive safely. This includes alcohol, prescription medications, over-the-counter medications, and illegal drugs.

When approaching a yield sign, drivers must give the right-of-way to traffic already in the lanes that they intend to enter or cross. Drivers should be prepared to stop when approaching a yield sign but may continue without stopping if there is no conflicting traffic.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that there is an upcoming sharp turn and that they should lower their speed accordingly.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to slow down and prepare for an abrupt change in direction at an extreme angle.

If a vehicle approaching you is using its high beams and fails to dim them, you should glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see well enough to stay on your course until the vehicle passes.

When it is difficult to see due to darkness or poor weather, increase your following distance. This will give you more time to react to hazards that you may not see in advance.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

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

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

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

If you maintain a valid DC driver license for a full calendar year without obtaining pointable moving violations, you may be eligible to receive a Good Point on your driving record.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

It is illegal to drive so slowly that you disrupt the normal flow of traffic. You may receive a citation for driving too slowly.

Blind spots are areas that a driver cannot see without moving their head. They can be located to the sides of and behind a vehicle.

Make room for vehicles that are entering a freeway. If possible, merge into the next lane to create a gap for the incoming vehicles. If you cannot merge, adjust your speed to allow for the vehicles to enter traffic as smoothly and safely as possible.

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.

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

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

After finding a parking space, checking traffic, and signaling, you should stop parallel to the vehicle directly ahead of your desired parking space before turning your wheel to park.

If you are involved in an accident, you must stop at or near the scene. Move your vehicle out of the way of traffic, if possible. Do not stand or walk in traffic lanes as you could be struck by another vehicle. Turn off the ignitions of wrecked vehicles.

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.
