Alaska CAR DMV Practice Test 18

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that left turns are prohibited.

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

A truck or bus has blind spots on each side, in the rear, and in the front. An automobile cannot be seen in these blind spots. These blind spots are referred to as the “No zone.”

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.

If you are on an entrance or acceleration ramp and are entering interstate traffic, you should yield to drivers already on the interstate highway. Merge safely into traffic when you are able to do so.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that there is an upcoming stop sign and that they should prepare to come to a complete stop before proceeding.

When following another vehicle under ideal driving conditions, you should maintain a minimum four-second following distance. Increase this following distance any time conditions are less than ideal.

To avoid rear-end collisions, it is helpful to look for break lights and other hazards in the traffic ahead of your vehicle. It is recommended that you maintain a following distance of four seconds when driving under ideal conditions.

You should not stop in a travel lane for any reason. Instead, keep moving until you can safely pull off of the road. If you miss your turn or exit, do not back up. Go to the next turn or exit or where you can safely turn around.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

You should never start a left turn until you can see that all the lanes you need to cross are clear and that you can safely make the turn.

A flashing red traffic signal has the same meaning as a stop sign. At an intersection with a flashing red light, you must come to a complete stop, look both ways, and proceed only after the intersection is clear.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

Yellow lines separate lanes of traffic moving in opposite directions. Double solid yellow lines indicate that passing is prohibited from either direction.

If your wheels drop off the pavement and onto a low shoulder, you should reduce your speed without braking and very carefully turn back onto the pavement. Be aware of any nearby traffic when re-entering the road.

Pennant-shaped warning signs like this are only used to indicate a no passing zone.

This sign indicates that hospital emergency services are located to the right.
