Highway England said it would cut speed limits on four motorway sections before October in a test to reduce pollution.
In areas where the recommended level of nitrogen dioxide is higher, it will decrease from 70mph to 60mph.
The trial will extend about five miles.
It will be 6 to 7 by Whitton, 33 to 34 by Rotherham at the M1 junctions, 1 to 3 by the MC 602 junctions and 1 to 2 by M51 at Oldbury.
Nitrogen dioxide (NO2) released from car emissions is a deadly air pollutant and indirectly contributes to global warming.
The effect of the new 60mph limit will be reviewed within a year
Evan Le Favre, head of environmental affairs at Highway England, said: “Ultimately, the challenge of air quality will be solved by ‘uninterrupted’ vehicle manufacturers and changes in vehicle usage.
“Until that happens, we will continue our comprehensive program of pioneering research and solutions.”
The Department of Transportation said the test was part of a series of measures to improve air quality.
As part of the plan to reduce NO2 levels, the government aims to finish selling all new conventional petrol and diesel cars and vans by 2040.
It has been suggested to move it forward to 2035, or earlier if a faster transformation is seen as possible, as well as to include hybrids for the first time.
The results of the consultation will be announced the next day.
