California CAR DMV Practice Test 3

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.

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

A single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.

A roundabout is a circular intersection that usually does not include a traffic signal and flows in a counterclockwise direction around a central island. Motorists must enter from the right, yielding to traffic already in the roundabout, and follow the circle to the right until the desired roadway is reached.

When driving in heavy rain at speeds as low as 30 mph, your tires may lose all contact with the road and instead ride up on a layer of water above the surface of the road. This is called "hydroplaning." If your vehicle starts to hydroplane, slow down gradually and do not apply the brakes.

Warning signs are usually yellow with black markings. This sign warns that your current road ends at an intersection straight ahead. Slow down and prepare to yield or stop before turning right or left.

When parking either uphill or downhill on a road that has no curb, you should turn your wheels so that the vehicle will roll away from the center of the road if the brakes fail.

You may sometimes turn right when stopped by a solid red light. You may never turn left or right when stopped by a traffic light with a red arrow.

Before merging into interstate traffic, you should identify a gap, accelerate to the speed of traffic, and signal. Merge into the gap when it is safe to do so. Be alert to other traffic and do not expect other drivers to clear the lane.

This sign indicates that turns in the direction of the arrow (in this case, to the right) are prohibited.

It is illegal to park your car on a marked or unmarked crosswalk. You may park in a bicycle lane if there is not a "No parking" sign posted and your vehicle does not block a bicyclist.

Because they are larger, trucks take longer to stop than cars traveling at the same speed. Other drivers should not pull in front of a truck and then slow down or stop.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

Tailgating is a common behavior that can lead to aggressive driving, and so it should be avoided. Drivers may face legal consequences for driving unsafely.

If a road has four or more lanes with two-way traffic, drive in the right lanes unless you are passing or turning left. If you are on an interstate highway and are driving below the speed of the flow of traffic, use the right lane.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

When passing another vehicle, move back into your original lane only when you can see the passed vehicle’s headlights in your rearview mirror. This ensures that you will have enough room to safely pull back in front of the other vehicle.

Slow down and be alert before entering the intersection. Yield to any pedestrians, bicyclists, or vehicles in the intersection. You do not need to stop for a flashing yellow traffic signal light.

When parking on a hill, you should always leave your vehicle in gear or in the "park" position. If there is no curb, you should turn your front wheels so that the vehicle will roll away from the center of the road if the brakes fail. If there is a curb, the front wheels should be turned toward it (if headed downhill) or away from and gently touching it (if headed uphill).

With decreased visibility and the glare of oncoming headlights, you cannot see as far ahead at night as you can during the day. Always use headlights and exercise caution when driving in the dark.

You must use your headlights at any time when conditions prevent you from seeing other vehicles and when it may be difficult for other drivers to see you. Always use your low beam headlights if weather conditions require you to use your windshield wipers.

Large trucks must often swing wide to complete a right turn. A truck making a right turn may initially appear to be turning left because of the need to swing wide. When behind a turning truck, you should pay attention to the truck's turn signal to be aware of which way the trucker actually intends to turn.

Even if the signal is green, you must not enter an intersection unless you can get completely across before the light turns red. If you block the intersection, you can be cited.

When turning left at an intersection, yield the right-of-way to oncoming traffic and pedestrians. Once the intersection is clear and applicable signals allow, you may complete the turn.

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.

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.

A flashing yellow signal means "proceed with caution." You should slow down and be alert before entering the upcoming intersection and must yield to any pedestrians, bicycles, or vehicles in the intersection; however, you do not have to stop.

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.

Excessive vehicle speed can have disastrous effects. As a vehicle's speed increases, the potential impact of a collision also increases, elevating the possibility of serious injury and death. Increase your following distance as your speed increases to ensure that you will be able to stop safely if needed.
