If a standard trans car rolls back at stop sign and hits that stopped too close behind it who is fault?

In most jurisdictions, the driver of the car that rolled backward would be at fault for hitting the car behind them. This is because they failed to maintain proper control of their vehicle. Even if the car behind was stopped too close, following too closely is generally a contributing factor, not a complete excuse for the rear-end collision. The driver of the rolling car had the primary responsibility to prevent the accident.
