Impaired Driving

Impaired driving is the term used to refer to offences of driving while impaired by alcohol or drugs. Impaired driving is sometimes called a DUI, DWI, drunk driving, driving under the influence or driving while intoxicated.

The offences include:

  • Driving while ability to drive is impaired by alcohol or drugs
  • Driving with a blood/alcohol level of .08 and over
  • Refusing to provide a breath sample
  • 90-day Administrative Driving Prohibition

Driving offences can have serious consequences for your future and your right to drive. We know that it is important for you to be able to drive and that is why it is important to us. We use all the advantages in the law to ensure you can keep driving.

You may still be innocent even if your breath samples were well over .08%. Drunk driving cases are often won on technicalities. The Police often make mistakes and we know how to make their mistakes work for you in court.

In most cases, we can protect your driving privileges and keep you from being convicted of an impaired driving offence.

    Being arrested and charged with a DUI, impaired driving, or causing a drunk driving accident, your daily life could get turned upside down. It’s very important you choose a DUI lawyer with a proven record of success in Alberta courts.

    • Termination of employment and career issues
    • Loss of license
    • Inhibited ability to work or care for children
    • Mandatory treatment programs / DUI classes

    Impaired Driving Laws and DUI Charges are not Set in Stone

    Drunk Driving Law states: it is illegal to operate a motor vehicle – having the care of control over that vehicle – while one’s ability to operate said vehicle is impaired by alcohol.

    DWI Laws state: if you are taken into custody on suspicion of driving drunk, a qualified technician will take samples of the accused driver’s breath into a breathalyzer – the Intoxylizer 5000C. The test determines how many milligrams of alcohol exists per 100 milliliters of blood.

    DUI Laws state: the charge of ‘over .08’ or ‘over 80’ is normally added if the driver’s breathalyzer sample registers over the legal limit of .08. The charge of refusal results when the operator of the motor vehicle refuses to either provide a sample of their breath into the Intoxylizer at the police station or into a certified breath screening apparatus at the roadside.

    With so much room for error during the police investigation and testing, our goal at Slaferek Callihoo is to have as much of the prosecutor’s evidence excluded. Charges of drunk driving, impaired driving, ‘over .08’, ‘over 80’, DUI, DWI, and refusal are complex and require police officers and technicians to follow strict rules and procedures. If the officer’s investigation stands up in court, the roadside screening device and/or the breath machine can be wrong; there are many options to explore when challenging their measurements.

    Our DUI defense team, at Slaferek Callihoo, are very qualified in examining the evidence and scrutinizing errors as to have as much evidence as possible excluded from the police investigation and the prosecution’s case against you.
