How MPI Determines Fault After a Manitoba Collision
MPI investigates collision responsibility using driver and witness statements, vehicle damage, police information, legislation and court decisions. The goal is to assess fault as a court likely would.
MPI adjusters assess fault using the facts, rules of the road, relevant law and court decisions.
An at-fault collision moves a driver down five levels on the Driver Safety Rating scale under current MPI guidance.
Deductible recovery can depend on the percentage of responsibility attributed to the other driver.
Fault can be shared
Responsibility does not have to be all-or-nothing. If the other driver is only partly responsible, deductible recovery can be proportional to that share. This is why a percentage fault decision can have a direct financial effect beyond the DSR.
Independent evidence matters
MPI says impartial witness reports can carry significant weight. Adjusters may compare statements with vehicle damage, police reports and the accident scene before deciding how a court would likely assign responsibility.
MPI is not the final court
If a driver disagrees with the responsibility assessment, Manitoba court procedures can ultimately determine fault. MPI also provides internal claim-review and appeal information before a dispute reaches that stage.
