ICBC Driver Factor Explained: Experience, Crashes & Premiums
Every B.C. driver has a three-decimal driver factor that represents driving risk. The reference point is 1.000: a lower number represents lower assessed risk and a higher number represents higher assessed risk.
The driver factor reflects driving experience and crash history, with additional treatment for some driver statuses.
A driver factor below 1.000 represents lower assessed risk than the reference point.
A policy can use a combined factor rather than simply copying the principal driver's individual factor.
Individual factor versus policy factor
Your individual driver factor is not necessarily the number that directly appears as the policy's final rating factor. ICBC combines driver information with policy-level adjustments, so two policies involving the same driver can still differ.
The 75/25 listed-driver structure
ICBC says that in most cases 75% of the Basic driver portion is based on the principal driver's factor and 25% is based on the listed driver with the highest risk. That makes accurate driver listing important when comparing renewals.
Why crash-free experience matters
As driving experience accumulates and a driver remains crash-free, the driver factor can improve. At-fault crashes can move it in the other direction, which is one reason a personal renewal can change even when province-wide Basic rates are stable.
Check the current ICBC rule or explanation
Canada Rate Lab summarizes the consumer-facing structure, but the official source controls if ICBC changes a rule, definition or rating practice.

Measure your own policy
Public rating rules explain the structure, but your renewal is the personal number that matters. Compare your old and new premium before attributing the change to one factor.
