Alcohol and Other Drugs
Alcohol and Other Drugs tests the legal limits, impairment signs, and consequences that follow a drunk-driving arrest in New York. Questions often ask you to distinguish DWI from DWAI, apply the under-21 rule, and recognize that only time removes alcohol.
Core rules
- DWI: driving with a blood alcohol concentration of 0.08% or more. Aggravated DWI: 0.18% or more. DWAI: driving while ability is impaired, commonly charged from 0.05% to 0.07% or when drugs impair driving.
- Zero tolerance: a driver under 21 with a BAC of 0.02% or more can face license consequences. Commercial drivers are held to a 0.04% standard.
- New York's implied consent law requires a chemical test after a lawful arrest. Refusing can bring license revocation and other penalties, even before conviction.
- Alcohol slows reaction time, reduces judgment, and impairs lane control. Prescription and over-the-counter drugs, marijuana, and combinations with alcohol can also cause impairment.
- Coffee, cold showers, and food do not sober you up. Only time lowers BAC.
Worked example
A 24-year-old driver is stopped with a BAC of 0.06%. That is below the 0.08% DWI threshold, but it does not make the driver legal. At 0.05% to 0.07%, New York can charge DWAI if evidence shows impaired driving. If the BAC were 0.08% or higher, DWI would apply.
Traps that cost marks
Believing coffee or a shower sobers you; assuming a prescription drug is always safe to drive with; and thinking refusal to test avoids consequences. Also do not confuse the under-21 threshold of 0.02% with the adult 0.08% limit.
