Almost 350 motorcyclists killed in collisions since 2012.
The OPP is marking Motorcycle Safety Awareness Month by encouraging motorcyclists to be cautious while traveling.
The police service says between 2012 and 2021, 342 motorcyclists were killed in 326 incidents.
In just over 60 percent of the cases, the person driving the motorcycle was reportedly the at-fault driver.
In 120 of the deaths, a single motorcycle was involved, and in the remainder, at least one other vehicle implicated.
The OPP says excessive speed, not yielding the right of way, and driver inattention are leading factors in motorcycle fatalities every year.
