3 questions on New Jersey’s own driver fitness rules
These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.
1. In New Jersey, for a driver younger than 21 it is illegal to drive with a BAC of:
- A0.08% or higher only
- B0.05% or higher
- 0.01% or higher
- D0.02% or higher
Answer: 0.01% or higher. The official New Jersey Driver Manual states that for individuals younger than 21, it is illegal to drive with a BAC of 0.01 percent or higher (N.J.S.A. 39:4-50.14).

2. New Jersey treats driving with a BAC of which level or higher as DUI/DWI for adult drivers?
- 0.08%
- B0.10%
- C0.01%
- D0.05%
Answer: 0.08%. The New Jersey Driver Manual states it is illegal to operate a motor vehicle while under the influence of intoxicating liquor, narcotic, hallucinogenic or habit-producing drugs, or with a BAC of 0.08 percent or higher (N.J.S.A. 39:4-50).
