Sample Oregon DMV practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

1. Question 1Rules of the Road

   You are approaching a multi-lane intersection where traffic is controlled by a solid green light. The lane you are in is marked with a straight-arrow-only symbol, but a vehicle in the adjacent left-turn lane is attempting to proceed straight through the intersection. What action must you take?

   • A.Change lanes to the left to avoid the other vehicle and proceed straight.
   • B.Proceed straight through the intersection, but be prepared to stop if the other vehicle obstructs your path.
   • C.Stop and wait for the other vehicle to clear the intersection before proceeding straight.
   • D.Proceed straight through the intersection as you have a green light.(Correct)

   Explanation

   You must proceed straight through the intersection because you have a solid green light and are in the correct lane for that movement. The other vehicle is in violation of lane usage rules. Do not change lanes or stop unnecessarily. Always be aware of other vehicles, but do not alter your legal movement due to another driver's error.

2. Question 2Alcohol, Drugs, and DUI

   You are driving and have consumed two standard alcoholic drinks over the past hour. You are 21 years of age or older. Which of the following is the MOST accurate statement regarding your potential Blood Alcohol Concentration (BAC) and driving ability, assuming average body weight and metabolism?

   • A.Your BAC will be 0.00% because you are under the legal limit for impairment.
   • B.Your BAC will be exactly 0.08% due to consuming two drinks, and you will be legally impaired.
   • C.Your BAC is likely below the legal limit of 0.08%, but your reaction time and judgment may still be impaired.(Correct)
   • D.Your BAC will be significantly above 0.08%, making you legally intoxicated and a danger to yourself and others.

   Explanation

   Even with a BAC below the legal limit of 0.08%, alcohol impairs cognitive functions essential for driving, such as judgment, coordination, and reaction time. Factors like body weight, food intake, and metabolism significantly influence BAC, making it impossible to state an exact percentage without testing. Consuming two standard drinks does not automatically equate to a 0.08% BAC, but impairment can begin at lower levels. Always drive sober; never drive after consuming any alcohol.

3. Question 3Alcohol, Drugs, and DUI

   You are stopped at a red light and have just finished a meal containing a small amount of alcohol. You are under 21 years old. Which of the following statements best reflects the legal implications of driving in this situation?

   • A.The legal limit for drivers under 21 is the same as for adults, 0.08%.
   • B.You are only in violation if you are visibly impaired or involved in an accident.
   • C.Even a trace amount of alcohol can lead to a DUI conviction if you are under 21 due to zero tolerance laws.(Correct)
   • D.Your Blood Alcohol Concentration (BAC) must be over 0.08% to be considered impaired, regardless of age.

   Explanation

   Under zero tolerance laws, drivers under 21 have a much lower BAC limit, often 0.01% or 0.02%, meaning even a trace amount of alcohol can result in a DUI. Option A is incorrect because the standard 0.08% limit applies to drivers 21 and older. Option C is incorrect as impairment is not a prerequisite for a DUI under zero tolerance; a detectable BAC is sufficient. Option D is incorrect because the legal limit for those under 21 is significantly lower than 0.08%. Always avoid alcohol completely when driving, especially if underage.
