Hawaii CAR DMV Practice Test 16

Guide signs, sometimes known as destination signs, have a green background and provide directional and mileage information to specific destinations. They can be a helpful resource when driving in unfamiliar locations.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that drivers are approaching a steep hill and should prepare to adjust their speeds to continue to drive safely.

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

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

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.

The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

You must always bring your vehicle to a complete stop and yield to approaching traffic before proceeding past a stop sign. Don't feel pressured by surrounding traffic to avoid making a complete stop.

Before changing lanes, check highway and traffic conditions ahead, to the sides, and to the rear of your vehicle. After checking your mirrors, check your blind spot by turning your head and looking over your shoulder in the direction of your move. Signal your intention at least 100 feet before you start the lane change. Don't move into a space between vehicles if doing so would interfere with their safe following distances.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

If you are stopped by the police, keep your hands on the wheel and ask any passengers to keep their hands in view as well. You should remain in the vehicle unless the police officer asks you to get out. Wait until the officer asks you to retrieve your driver license, registration, and insurance cards.

If there is no stop line or crosswalk, you should stop at the point nearest to the intersecting roadway where you can get a view of approaching traffic. You should not enter the intersecting roadway to gain a better view.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

When you hear the siren or see the flashing lights of an emergency vehicle coming from behind your vehicle, you must create a clear path for the emergency vehicle and stop. Reduce your speed and safely pull over to the side of the road. If the emergency vehicle is directly behind your vehicle when you are in heavy traffic, keep moving slowly until you can get out of its way.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

This sign indicates that a school crossing is ahead.

Crashes often happen when some drivers go faster or slower than other vehicles on the road. Always try to drive with the flow of traffic, within the posted speed limit.

Almost all of the information you need in order to safely drive is obtained by seeing. You should have a constant awareness of conditions in your vehicle's vicinity. Special attention should be devoted to conditions a considerable distance ahead of your vehicle.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.

A triangular red and white yield sign means that you must decrease speed as you approach an intersection and yield the right-of-way to any vehicles or pedestrians in the intersection. You must be prepared to stop if conditions require it.

White lines are used to separate traffic moving in the same direction. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

A solid yellow arrow has the same meaning as a yellow traffic light. When approaching a solid yellow arrow, you must reduce your speed and prepare for a red light.

This sign warns drivers that the divided highway ends ahead.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.
