Question 1. In Ohio, at what blood alcohol concentration (BAC) is a driver 21 or older violating the OVI law, even without other signs of impairment?
- ① 0.02% or more
- ② 0.08% or more
- ③ 0.10% or more
- ④ 0.15% or more
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② 0.08% or more
Key point: Adult per se limit: 0.08%
Ohio's OVI law (operating a vehicle impaired) makes it illegal to drive with a BAC of 0.08% or more. A driver can also be charged at a lower level if alcohol or drugs affect their driving.
Wrong choices
- 0.02% or more: 0.02% is the limit for drivers under 21.
- 0.10% or more: 0.10% is above Ohio's limit. 0.08% is already illegal.
- 0.15% or more: 0.15% is not the number in Ohio's OVI law. The basic limit is 0.08%.
Question 2. What is the blood alcohol limit for drivers under 21 in Ohio?
- ① 0.02%
- ② 0.05%
- ③ 0.08%
- ④ 0.10%
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① 0.02%
Key point: Under 21: illegal at 0.02% or more
Ohio law makes it illegal for a driver under 21 to drive with a BAC of 0.02% or more. At 0.08% or more, the regular OVI law applies as well.
Wrong choices
- 0.05%: 0.05% is not Ohio's limit for young drivers. The limit is 0.02%.
- 0.08%: 0.08% is the limit for drivers 21 and older.
- 0.10%: 0.10% is higher than both of Ohio's limits.
Question 3. Which of these can sober up a person who has been drinking alcohol?
- ① Only time
- ② Black coffee
- ③ Fresh air
- ④ A cold shower
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Only time
Key point: Only time removes alcohol from the body
Only time lowers the alcohol level in the body. Coffee, cold showers, and fresh air may make a person feel more awake, but they do not remove alcohol or make driving safe.
Wrong choices
- Black coffee: Coffee may make a person more alert but does not lower the BAC.
- Fresh air: Fresh air does not lower the BAC.
- A cold shower: A cold shower does not remove alcohol from the body.
Question 4. What does Ohio's implied consent law mean?
- ① A police officer must have your written consent before any test
- ② You may refuse any chemical test without any penalty
- ③ By driving in Ohio, you are considered to have agreed to a chemical test of your blood, breath, or urine if arrested for OVI
- ④ You must agree to have your car searched any time you are stopped
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ By driving in Ohio, you are considered to have agreed to a chemical test of your blood, breath, or urine if arrested for OVI
Key point: Implied consent: driving = agreeing to an OVI test
Under Ohio's implied consent law, anyone who drives in Ohio is deemed to have consented to a chemical test (blood, breath, or urine, among others) if arrested for OVI. Refusing brings an administrative license suspension.
Wrong choices
- A police officer must have your written consent before any test: No written consent is needed. Consent is implied by driving.
- You may refuse any chemical test without any penalty: Refusing a test brings a license suspension.
- You must agree to have your car searched any time you are stopped: The law is about chemical tests for alcohol and drugs, not searching your car.
Question 5. An adult driver is arrested for OVI and refuses a chemical test for the first time. How long is the administrative license suspension?
- ① 90 days
- ② 6 months
- ③ 1 year
- ④ 3 years
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ 1 year
Key point: First test refusal: 1-year suspension
For a first refusal of a chemical test, Ohio law imposes an administrative license suspension of one year (a class C suspension). Refusals or OVI convictions in the past 10 years make it longer.
Wrong choices
- 90 days: 90 days (three months) is the suspension for a first failed test, not a refusal.
- 6 months: 6 months is not the period for a first refusal.
- 3 years: 3 years applies only after several prior refusals or convictions.
Question 6. A driver takes a legal medicine that makes them drowsy and their driving is affected. Can this be OVI?
- ① Yes, OVI covers impairment by alcohol, drugs, or both
- ② No, if the medicine is legal there is no offense
- ③ Only if the driver also has a BAC of 0.08% or more
- ④ No, OVI covers only alcohol
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Yes, OVI covers impairment by alcohol, drugs, or both
Key point: OVI covers alcohol, drugs, or both
Ohio's OVI law makes it illegal to drive under the influence of alcohol, a drug of abuse, or a combination of them. Read medicine labels and do not drive if a medicine makes you drowsy or affects your driving.
Wrong choices
- No, if the medicine is legal there is no offense: A medicine being legal does not make impaired driving legal.
- Only if the driver also has a BAC of 0.08% or more: A driver can be impaired by drugs with no alcohol at all.
- No, OVI covers only alcohol: OVI includes drugs, not only alcohol.
Question 7. Which of these statements about Ohio's alcohol laws is NOT true?
- ① A driver 21 or older with a BAC of 0.08% or more is violating the OVI law
- ② Only time can lower a person's blood alcohol level
- ③ A first refusal of a chemical test brings a one-year administrative suspension
- ④ A driver under 21 with a BAC of 0.05% is within the law because it is below 0.08%
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ A driver under 21 with a BAC of 0.05% is within the law because it is below 0.08%
Key point: Under 21: 0.02% is already illegal
For drivers under 21, Ohio's limit is 0.02%, so a BAC of 0.05% is against the law. The other statements are true.
Wrong choices
- A driver 21 or older with a BAC of 0.08% or more is violating the OVI law: This is true. 0.08% is the limit for drivers 21 and older.
- Only time can lower a person's blood alcohol level: This is true. Coffee and fresh air do not lower BAC.
- A first refusal of a chemical test brings a one-year administrative suspension: This is true. A first refusal brings a one-year suspension.
Question 8. An adult driver takes a chemical test after an OVI arrest and tests at 0.08% or more. If it is a first offense, how long is the administrative license suspension?
- ① 30 days
- ② 3 months
- ③ 1 year
- ④ 2 years
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② 3 months
Key point: First failed test: 3-month suspension
When a test shows a BAC of 0.08% or more and the driver has no OVI in the past 10 years, Ohio law imposes an administrative license suspension of three months (a class E suspension). A refusal brings a longer suspension.
Wrong choices
- 30 days: 30 days is shorter than Ohio's three-month period.
- 1 year: 1 year is the suspension for a first refusal.
- 2 years: 2 years applies only when there are prior OVI convictions.
Question 9. For a first OVI conviction, what range of license suspension does Ohio law require a court to impose?
- ① 30 to 90 days
- ② 6 months to 1 year
- ③ 1 to 3 years
- ④ Lifetime
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ 1 to 3 years
Key point: First OVI conviction: 1 to 3 year suspension
For a first OVI conviction, Ohio law requires a court suspension of 1 to 3 years, a fine of $565 to $1,075, and a mandatory three days in jail or a three-day driver intervention program. The court may grant limited driving privileges.
Wrong choices
- 30 to 90 days: 30 to 90 days is far shorter than the law requires.
- 6 months to 1 year: 6 months to 1 year is shorter than the 1-to-3-year range.
- Lifetime: Lifetime suspensions are not the rule for a first offense.
