Question 1 of 7
  1. 1. You are 25, hold an ordinary non-probationary license, and are driving a private car on a New Hampshire road. What is the ordinary adult threshold for the law that prohibits driving based on alcohol concentration itself?
  2. 2. A 20-year-old drives a private car on a New Hampshire road with an alcohol concentration of 0.02. The driver argues that only the ordinary adult 0.08 threshold matters. Which statement is correct?
  3. 3. A legally prescribed medicine is impairing your ability to drive. You have consumed no alcohol. Does having a valid prescription make it lawful to drive your private car on a New Hampshire road while impaired by that medicine?
  4. 4. You are arrested for an offense arising from alleged impaired driving of your private car on a New Hampshire road. An officer with reasonable grounds directs a breath test under the implied-consent law. No crash is involved. Which statement describes the consent rule in these circumstances?
  5. 5. You are conscious and under arrest in an ordinary impaired-driving case with no death or serious-injury crash. Before an officer-directed breath test under §265-A:4, which additional-test right must you be told about and given an opportunity to request?
  6. 6. After an impaired-driving arrest and the required warnings, a driver refuses an officer-directed test under §265-A:4. The driver assumes the refusal cannot be mentioned in any related case. What does New Hampshire law say?
  7. 7. A licensed private-car driver refuses a qualifying post-arrest test after the required warnings. The officer submits the statutory sworn report, but the criminal case has not yet resulted in a conviction. Can the refusal still lead to an administrative license suspension?

  1. You are 25, hold an ordinary non-probationary license, and are driving a private car on a New Hampshire road. What is the ordinary adult threshold for the law that prohibits driving based on alcohol concentration itself?

    Correct answer: 0.08 or more.

    Section 265-A:2 I(b) sets the ordinary adult concentration prohibition at 0.08 or more. This is not permission to drive below that level while impaired: the separate impairment prohibition in I(a) still applies.

  2. A 20-year-old drives a private car on a New Hampshire road with an alcohol concentration of 0.02. The driver argues that only the ordinary adult 0.08 threshold matters. Which statement is correct?

    Correct answer: The concentration prohibition for a person under 21 begins at 0.02 or more.

    Section 265-A:2 I(b) expressly uses 0.02 or more for a person under 21. Holding a full license or driving alone does not replace that age-based threshold with the ordinary adult threshold.

    Source: New Hampshire General Court, RSA Chapter 265-A, Alcohol or Drug Impairment; §265-A:2 I(b), reader line 39; displayed history 2006, 260:1 and 2012, 267:2, effective January 1, 2013, line 42.

  3. A legally prescribed medicine is impairing your ability to drive. You have consumed no alcohol. Does having a valid prescription make it lawful to drive your private car on a New Hampshire road while impaired by that medicine?

    Correct answer: No. The impairment prohibition includes prescription drugs that impair the ability to drive.

    Section 265-A:2 I(a) includes impairing prescription drugs, over-the-counter drugs and other listed substances, whether or not alcohol is involved. A lawful prescription does not create an exemption for driving while impaired. This does not mean that every medicine causes impairment.

  4. You are arrested for an offense arising from alleged impaired driving of your private car on a New Hampshire road. An officer with reasonable grounds directs a breath test under the implied-consent law. No crash is involved. Which statement describes the consent rule in these circumstances?

    Correct answer: Driving on the state’s ways is treated as consent to the qualifying tests in this statutory arrest and reasonable-grounds setting.

    Section 265-A:4 provides deemed consent in its specified arrest and reasonable-grounds framework. It is not limited to crashes or to a driver who signed a separate advance form. This scenario concerns the post-arrest statutory test, not the separate preliminary breath test that may be requested without arrest under §265-A:15.

  5. You are conscious and under arrest in an ordinary impaired-driving case with no death or serious-injury crash. Before an officer-directed breath test under §265-A:4, which additional-test right must you be told about and given an opportunity to request?

    Correct answer: The right, at your own expense, to an additional blood test by a person of your choosing who is competent to conduct it.

    Sections 265-A:7 and 265-A:8 provide the additional-test right, information and an opportunity to request it. The test is at the person’s own expense and must be conducted by a competent person. It does not replace the officer-directed test or require release from custody; inability to obtain it does not by itself exclude the officer-directed test.

  6. After an impaired-driving arrest and the required warnings, a driver refuses an officer-directed test under §265-A:4. The driver assumes the refusal cannot be mentioned in any related case. What does New Hampshire law say?

    Correct answer: The refusal may be admitted as evidence in a related civil or criminal action or proceeding.

    Section 265-A:10 says a refusal of a test under §265-A:4 may be admissible in related civil or criminal proceedings. It does not make refusal automatic proof of guilt. The separate treatment of a preliminary breath test requested without arrest under §265-A:15 is not the scenario here.

    Source: New Hampshire General Court, RSA Chapter 265-A, Alcohol or Drug Impairment; §265-A:10, reader line 122, displayed history effective January 1, 2013, line 123; preliminary-test distinction §265-A:15 I, lines 197–200, history effective January 1, 2013, line 204.

  7. A licensed private-car driver refuses a qualifying post-arrest test after the required warnings. The officer submits the statutory sworn report, but the criminal case has not yet resulted in a conviction. Can the refusal still lead to an administrative license suspension?

    Correct answer: Yes. The refusal can trigger administrative suspension without first obtaining a criminal conviction, subject to the statutory notice and review process.

    Sections 265-A:14 and 265-A:30 provide administrative consequences for a qualifying refusal through the officer’s sworn report and the statutory notice process. Section 265-A:31 provides administrative review or a hearing. A criminal conviction is not a prerequisite, but neither is the suspension described here as instantly effective or unreviewable. No suspension duration is stated.
