TIPS TO REMEMBER FOR AVOIDING DUI CHARGES IN ONTARIO
- Plan Ahead: Arrange a safe ride home before drinking or using cannabis.
- Check Your Medications: Some prescription and over-the-counter drugs can impair your ability to drive. Ask your doctor or pharmacist about potential effects.
- Read Labels Carefully: Many medications include warnings about drowsiness or slowed reaction time.
- Avoid Mixing Substances: Combining alcohol with drugs, including cannabis, can intensify impairment.
- Understand the Impact of Fatigue: While driving while fatigued is not usually a criminal offence by itself, in certain circumstances it can support a dangerous driving or criminal negligence charge if there is an accident. Fatigue can also cause poor performance on sobriety tests, potentially leading to a DUI arrest and other legal consequences.
- Understanding Police Powers at the Roadside: Police have a variety of tools to determine whether you can be arrested for a DUI-related offence at the roadside. If you are the subject of a lawful demand to perform a test, whether a Standard Field Sobriety Test (walk and turn, horizontal gaze nystagmus, or one leg stand) or to provide a sample into an Approved Screening Device, you must cooperate and complete the test or you can be charged with refusal. However, you are not required to answer their questions. You have the right to remain silent, and you should use it.
