A sophisticated system to evaluate in-vehicle safety has been developed by the Transport Research Laboratory (TRL) in the UK.

A product is scored in each category with an overall score determined to allow a TRL recommendation status to be given to the product. The evaluation protocol can be used to provide independent support for the claimed benefits of the evaluated product and/or to provide exp
