The vehicle accelerated up a hill as the contact was unable to depress the brake pedal; he collided with an electric pole which caused the vehicle to stop. Due to the shock and abruptness of the failure, the contact was uncertain if any warning lights illuminated the instrument panel. The air bags did not deploy upon impact. The contact and no other bystanders were injured as a result of the failure. …”
