3 questions from the Oklahoma practice test
1. What alcohol condition violates Oklahoma's Zero Tolerance Law for a driver under 21?
- Only alcohol combined with a traffic collision
- Only a BAC of 0.02 or higher
- Only a BAC of 0.08 or higher
- Any measurable quantity in the blood or breath
Show answer
Any measurable quantity in the blood or breath. Oklahoma's under 21 rule prohibits driving, operating, or being in actual physical control with any measurable quantity of alcohol in the person's blood or breath when tested. It does not wait for 0.02 or 0.08, and a collision is not required. The word measurable is the exam cue: a small detected amount is enough for this special rule, even though adult criminal and administrative thresholds use different figures.
2. After a first Zero Tolerance conviction or offense, how long is the Oklahoma license revocation period?
- 30 days
- Six months
- Twelve months
- Two years
Show answer
Six months. The first listed Zero Tolerance revocation period is six months. Twelve months belongs to the second conviction or offense, while two years is not the first-offense period in this section. Thirty days appears elsewhere in the manual as a suspension period in another alcohol-related context, so it is an especially tempting mix-up. When studying this chart, connect first offense with six months and second offense with twelve months.
3. A 15 year old in Oklahoma loses driving privileges under the Zero Tolerance law, and the revocation would end before the 16th birthday. What does Service Oklahoma do?
- Ends the cancellation on schedule
- Makes the cancellation permanent
- Extends the cancellation until the person turns 16
- Replaces it with community service
Show answer
Extends the cancellation until the person turns 16. When a person is under 16 at the time, or would still be under 16 when the cancellation ends, Service Oklahoma extends the cancellation until the person reaches 16. So it does not simply end on the original date. It is not permanent, and community service is a possible penalty alongside revocation rather than a replacement for it. This keeps a young offender from driving before the normal licensing age.
