Sample question from test 1
alcohol
A New Jersey driver who is 21 or older has a BAC reading of 0.08 percent. What does that reading mean?
- It reaches the illegal adult threshold
- It is below every alcohol-related limit
- It is legal unless the driver feels impaired
- It triggers only a warning for a first stop
Answer: It reaches the illegal adult threshold. For an adult motorist, New Jersey treats a BAC of 0.08 percent or higher as illegal, even though impairment can begin well below that level. The option requiring a crash adds an event the rule never requires. A reading of 0.05 percent is associated with increased crash risk in the same discussion, not permission to drive freely. On a test, pair the driver’s adult age with the 0.08 figure and remember that a breath result is a measurement of alcohol concentration.
