Refusing Breathalyzer Tests
- the driver may pass the test
- breath tests give another issue to dispute
- low breathalyzer readings maybe eligible for reduced charges
Where a driver refuses to take the breath test, the defence will deal with the issues of:
- did the accused have a lawful reason to refuse
- did the police had a right or the grounds to demand a breathalyzer test and
- did the accused fail without lawfully authority to provide the breath test to the officer
- did the accused understand the implications of refusing the test

A driver can refuse a breathalyzer test if they wish to do so. You cannot be physically forced to submit to a breathalyzer test.
Where the driver does refuse to take the breath test the police can charge the driver with the criminal offence of “Refusing a Breathalyzer Test”.
The penalty for refusing the breath test is the same penalty as if the driver took the test and failed.

Fighting Refuse Breathalyzer Test Charges
The police do make mistakes and they don’t win every case, just because you have charged doesn’t mean you’re guilty.
Charges for refusing a breathalyzer test can be won. There are defences to refusing a breathalyzer, compromises and resolutions other than being found guilty and losing your licence.
Although the charge may seem straightforward in that the driver either “did or did not provide a breath sample”, there are legal issues that must be proven to convict a driver of this charge, for example:
- did the police have the legal right to make the demand
- did the police clearly explain the obligation to the driver
- did the driver understand what the officer was telling them
- did the accused have the opportunity to speak the a lawyer
- were the rights of the accused abused in any way by the police
The police have a legal responsibility to ensure that when they demand a breathalyzer test:
- that the driver understands
- the implications if they do not comply,
- the driver knows what they are required to do,
- the driver was given reasonable opportunity to provide the sample
Many times this is not done properly. If the accused did not fully understand, or the police did not explain properly or give the driver a reasonable opportunity to provide the breath sample, then this can become a defence to the charge.
It’s your right to have a judge hear your case and make and impartial decision based upon the facts.
It’s for the judge to decide if everything was done properly, legally and has a case been made out beyond any reasonable doubt.
You’re not guilty unless a judge says you are, not the police or the crown attorney.
★★★★★ Excellent lawyer!!! Nicholas was a pleasure to deal with. He knows the DUI laws inside and out. Not only did he get my impaired driving and refuse breath test dropped but he cleared my name from the police database. I wouldn’t hesitate referring him to my friends and family if any of them were to be charged with DUI or related matters. Jacob C. Toronto (Google Reviews)
