Oklahoma Product Defective If No Warning Given is a legal term used to describe an item that has been designed, manufactured, or sold without providing a sufficient warning of any possible risks associated with its use. This type of product defect can be either an express or an implied defect. Express Defect: An express defect is one where the manufacturer or seller has provided a clear and direct warning of a potential hazard with the product. This warning can be in the form of a label, a warning message, or instructions included with the product. Implied Defect: An implied defect is one where the manufacturer or seller has not provided any warning of potential hazard or danger with the product. This type of defect is usually based on the reasonable expectancies of the consumer and is determined by the type of product, the manner in which it is used, and the circumstances in which it is used. In either case, when a product is found to be defective due to a lack of warning, the manufacturer or seller can be held liable for any damages resulting from the use of the product.
