Arkansas: DMV Practice test - Practice Test 8

Every 0.02 percent increase in blood alcohol concentration nearly doubles a driver's risk of being in a fatal crash.

To drive quickly, pass, or turn left, use the left lane. Use the right lane when driving more slowly than surrounding traffic, entering the road, or turning right.

Before you return to your driving lane, be sure you are not dangerously close to the vehicle you have just passed. One way to do this is to look for the vehicle in your inside rearview mirror. When you can see both headlights in your rearview mirror, you may have enough room to return to your driving lane.

Both hands should be placed on opposite sides of the steering wheel. This position is comfortable and promotes safe turning on high-speed roadways.

You must yield the right-of-way to any emergency vehicle that is using its siren and lights. Drive to the right edge of the road and stop until the emergency vehicle has passed. If you are within an intersection, drive through the intersection first and then stop.

A driver's ability to safely operate a vehicle may be impaired at any BAC level, even a level lower than the legal limit. Any amount of alcohol can affect one's judgment and physical coordination. Driving under the influence of even a small amount of alcohol can lead to criminal charges.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

A five-sided yellow or yellow-green sign alerts drivers to either a school zone or school crossing.
