In Alberta, police treat refusing a breath test just as seriously as impaired driving.
In short, you can face serious consequences. What’s more, the Crown doesn’t need to prove you were driving over the legal limit if the police can show that you refused a lawfully demanded breath test.
So, let’s break down exactly:
- what happens during a traffic stop,
- what refusal means under Alberta law,
- and what your options may be moving forward.
Can police demand a breath test at a traffic stop in Alberta?
Yes. Police have broad authority during traffic stops, including the power to demand a roadside breath sample.
Under federal impaired driving laws, officers can require a driver to provide a breath sample into an Approved Screening Device (ASD).

Police can demand a breath test with or without needing a reasonable suspicion of impairment. In other words, this means they don’t need to:
- Smell alcohol
- Observe slurred speech
- See poor driving
That being said, police must make the demand lawfully under the Criminal Code, which means:
- The traffic stop itself must be valid
- The officer must clearly communicate the breath demand
- You must have a reasonable opportunity to comply
If you refuse a lawful demand, the consequences are immediate and severe (even if you weren’t actually impaired).
What happens immediately after you refuse a breath test in Alberta?
Refusal triggers two parallel processes:
- Immediate roadside administrative penalties
- A criminal charge under the Criminal Code
Both can significantly impact your licence, finances, and future.

These administrative penalties are separate from any criminal court proceedings and can apply before you’re convicted of anything.
Criminal Charges for Refusing to Provide a Breath Sample
Unlike an “over 0.08” charge, the Crown does not need to prove you were over the legal limit. Instead, the focus becomes whether:
- A lawful demand was made
- You failed or refused to comply
If charged, you may face:
- A criminal record upon conviction
- A mandatory minimum fine for a first offence
- A court-ordered driving prohibition
- Increased penalties for subsequent offences
- Possible jail time for repeat offences
Is Refusing a Breath Test Worse Than a DUI?
Many drivers assume that refusing a breath test might protect them from an impaired driving charge.
In reality, refusal is treated just as seriously — and sometimes more harshly — than driving over 0.08.

Can You Refuse a Roadside Sobriety Test in Alberta?
Let’s be clear: there is an important legal distinction between a roadside breath test and a physical sobriety test.
Unlike a breath demand, field sobriety tests are not automatically mandatory in every situation. However, refusing one may give the officer further grounds for an arrest.
Are Refusal Charges Defendable in Alberta?
Yes, depending on the circumstances, a defence may involve questions such as:
- Was the traffic stop itself lawful?
- Was the breath demand made under the correct section of the Criminal Code?
- Was the demand made promptly?
- Was it clearly explained?
- Did the driver understand what was being required?
- Was there a medical inability to provide a sample?
- Were Charter rights violated during the stop or detention?
Because refusal charges focus on the legality of the demand (not on blood alcohol readings) the defence strategy is often very different from an over-0.08 case.
Do I Need a Lawyer for a Refusal Charge in Alberta?
Yes, it’s crucial you speak with a criminal defence lawyer as soon as possible.
Refusal cases are technical and focus on legal procedures.
If you’ve been charged with refusing a breath test during a traffic stop, early legal advice can significantly impact how your case proceeds.
