Defending Calgary Impaired Driving Charges

Impaired driving, also known as “driving under the influence,” is one of the most common driving offences charged under the Criminal Code of Canada. It refers to the act of operating a vehicle while impaired by drugs or alcohol. This includes driving with a blood alcohol concentration (BAC) of 0.08% or higher or with any amount of drugs or a combination of drugs and alcohol that impairs a person’s ability to drive safely.

If an individual exhibits signs of driving under the influence of substances like alcohol or drugs that impair their ability to drive safely, such as swerving on the road, the police may arrest and charge them for impaired driving. After the arrest, the prosecution must prove that the individual operated the vehicle and that they were voluntarily impaired by a substance (alcohol, drugs, or a combination thereof).

The prosecution may also upgrade the charges if the accused individual caused serious harm as a result of impaired driving, also known as impaired driving causing bodily harm or impaired driving causing death.

It is important to note that impaired driving charges can be contested in court, and individuals facing such charges are encouraged to seek legal counsel to defend their rights and minimize the impact of these charges on their lives.

What are the consequences of an impaired driving charge?

The penalties for impaired driving can include fines, license suspension, and even imprisonment. However, they vary depending on the severity of the offence, as well as other factors such as the offender’s prior record, the degree of impairment, and whether any accidents or injuries occurred.

For a first offence, an individual may face a fine of up to $5,000, a license suspension of up to one year, and up to 10 years in prison if the impaired driving causes bodily harm or death. A second offence may result in higher fines, longer license suspension, and longer prison sentences.

In addition to criminal charges, impaired driving can also have significant personal and professional consequences, including damage to one’s reputation, loss of employment, and difficulties obtaining future employment

Defences to impaired driving charges

There are several common defences to impaired driving charges, including:

  • Challenging the evidence of impairment: The defence may challenge the reliability of the evidence used to prove that the accused was impaired at the time they were operating the vehicle, such as the results of a breathalyzer or blood test, arguing that it was obtained improperly or is inaccurate.
  • Arguing that the stop was unlawful: Police must have a lawful reason to pull someone over and conduct a breathalyzer or blood test. The defence may argue that the stop was made unlawfully, and as such, any evidence obtained following the stop should be inadmissible in court.
  • Providing a reasonable explanation for the behaviour: The defence may argue that there is a reasonable explanation for the accused’s behaviour that led to the charges, such as a medical condition that affected their ability to drive safely.
  • Challenging the legality of the arrest: If the arrest was made unlawfully or without sufficient cause, the defence may argue that the charges should be dismissed.

Each case is unique, and the best defence strategy will depend on the specific circumstances of the case. With more than 35 years of experience, Patrick C Fagan, K.C. knows how to develop a successful strategy that best suits your case.
