Impaired driving laws in New Brunswick

Impaired driving is one of the main causes of serious crashes in New Brunswick. For a new driver the rule is simple: no alcohol and no drugs at all before driving.

Since January 1, 2025, police in New Brunswick can also hand out tough roadside penalties to any driver, on top of the Criminal Code.

By the end of this topic you can

  • You can state the alcohol limit that applies to you as a new driver.
  • You can explain what happens to a graduated licence after a zero tolerance breach.
  • You can describe the roadside penalties at 0.05 and at 0.08.
  • You can explain why cannabis and other drugs are treated the same way.
  • You can plan a safe way home that does not involve impaired driving.

What you need to know and understand

  • While you hold a Class 7 graduated licence, your blood alcohol must be zero and you must not drive after using drugs.
  • Drivers under 21 also have a zero alcohol restriction on their licence, even after they reach Class 5.
  • A zero tolerance breach on a graduated licence means a one-year suspension, a mandatory seven-day vehicle impoundment and a return to the start of the program.
  • The Criminal Code limit for all drivers is 80 mg of alcohol per 100 mL of blood (0.08).
  • A reading of 0.05 or more, or a poor Standard Field Sobriety Test, brings a seven-day roadside suspension for a first offence in five years.
  • A reading of 0.08 or more, or refusing a test, can bring a three-month roadside suspension and a 12-month ignition interlock.
  • Driving while impaired by drugs is illegal under the Motor Vehicle Act as well as the Criminal Code.

The two roadside penalty levels

These administrative penalties apply to every driver. A graduated driver also faces the zero tolerance penalties above.

  • 0.05 or more, or a failed sobriety test: 7-day suspension for a first offence in five years, 15 days for a second and 30 days for a third. The vehicle is impounded for 3 to 7 days, and there is an administrative penalty of $240 to $480 plus a reinstatement fee.
  • 0.08 or more, or refusing a demand: licence surrendered on the spot and suspended for three months, 30 or 60 days of vehicle impoundment, an impaired driver re-education course ($380 or $690), a $230 reinstatement fee, a $1,200 to $2,400 penalty and a 12-month ignition interlock at your own cost.

Criminal charges as well

Police can choose the roadside route or a Criminal Code charge. The roadside route is not used where someone is seriously hurt or killed, or where a passenger under 16 is in the vehicle. A Criminal Code conviction can also bring a long suspension, a criminal record and much higher insurance costs.

Police can also suspend a licence for 24 hours if they believe a driver is unfit to drive safely for a medical or other reason, such as extreme fatigue.

Making the safe choice

  • Decide before you go out how you will get home.
  • Never ride with a driver who has been drinking or using drugs.
  • Remember that cannabis can slow your reactions for hours, and mixing it with alcohol makes things worse.
  • Check medicine labels and ask a pharmacist if a prescription or over-the-counter drug could affect your driving.
  • Coffee, cold air and food do not make you sober. Only time does.

Common mistakes

  • Thinking one drink is fine on Level 2. The limit for graduated drivers is zero.
  • Believing the zero rule ends when you get Class 5. If you are under 21, it still applies.
  • Driving the morning after a heavy night. Alcohol may still be in your blood.
  • Assuming cannabis is safer than alcohol for driving. Drug-impaired driving is illegal and dangerous.
Practice tip: Agree a no-questions-asked pickup plan with your supervising driver or a family member, so calling for a ride is always easier than driving impaired.
