Impaired driving: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
5.9 Impaired driving (pp. 64–67)
- All drivers under 21 must keep a zero Blood Alcohol Concentration (BAC). Zero tolerance for drug-impaired driving applies to novice drivers and those under 21. (Part 1 adds: graduated licence holders must keep 0% BAC and no impairing drugs.)
- Besides losing driving privileges, an impaired conviction can mean higher insurance rates, difficulty getting insurance, or job loss.
- Main factors in alcohol impairment: amount absorbed into the blood and time allowed for elimination; also body weight, food in the stomach and type of drink.
- "Wearing off" feeling is a delusion: you compare peak impairment with declining impairment, but you are not sober.
- Some prescription and over-the-counter drugs (for colds or flu) cause drowsiness; avoid driving and never mix with alcohol.
- Plan a safe ride: designated driver, cab or public transit.
- Drug impairment (including cannabis): police can seize vehicles and suspend licences on the spot; consequences include immediate short-term roadside suspension, administrative licence suspension, vehicle impoundment, re-education course, reinstatement fees.
- Criminal Code: driving with BAC of 80 mg per 100 mL of blood (0.08%) or more is prohibited.
- Warning range 0.05–0.08%: penalties under NB's Motor Vehicle Act. Vehicle impoundment: 1st offence within 5 years 3 days (discretionary); 2nd within 5 years 7 days (discretionary); 3rd or more within 5 years 7 days (mandatory).
- BAC 0.08 or over, or failing/refusing a breath sample (listed under the Vehicle Impoundment Program): first within 10 years = 30-day mandatory impoundment; with a previous one within 10 years = 60-day mandatory impoundment.
- Novice drivers who break the zero tolerance rule: mandatory seven-day vehicle impoundment.
- Ignition interlock: mandatory for everyone convicted of alcohol-impaired driving or of failing/refusing a Criminal Code demand; prevents starting the vehicle after drinking; restricted licence for interlock-equipped vehicles only; the participant pays. Voluntary program for drivers on a 30-day short-term suspension or a three-month Administrative Licence Suspension for alcohol. The Registrar can extend time in the program or grant exemptions.
- Police may suspend a licence for 24 hours if they believe a driver is unfit to drive safely for a medical or other reason.
- Police with reasonable grounds may demand a standard field sobriety test, a breath or bodily substance sample, or a Drug Recognition Expert evaluation. Conviction for failing or refusing = same penalties as impaired driving.
