Many Ontario crashes involving suspected impairment share a few realities:
- Commute-and-corridor driving: Incidents on busy arterial roads and near shopping/restaurant areas can involve sudden lane changes, late braking, or erratic trajectory.
- Nighttime visibility issues: After dark, glare, speed, and limited lighting can create disputes about what the driver actually saw—and what officers later documented.
- Busy intersection moments: Crashes near signalized intersections often lead to competing accounts about right-of-way, speed, and reaction time.
- “It happened fast” witness statements: People remember details differently when they’re shocked—so inconsistencies can become a negotiation issue later.
Because these cases often hinge on what was observed and when, your next steps matter.
