Which purpose does a type approval emissions standard serve?

  • A.Setting limits a new vehicle must meet before sale
  • B.Setting the limits applied at the annual inspection, which every vehicle must satisfy throughout its service life
  • C.Nothing
  • D.Defining the maximum emissions a new model may produce, measured under a prescribed test before it may be sold

Answer: A

Type approval binds the manufacturer before the model may be placed on the market. The last option explains exactly that, which makes it a correct and more precise version. Periodic inspection is a separate regime. The shared behaviour explains why these belong together and the differences explain why both exist. Naming what changes and what stays the same is the reliable route through questions of this shape. Most errors here come from carrying a result across from a neighbouring case where it does not hold.
