Tractors and construction machinery

The first emission standards specifically set for tractors and construction equipment vehicles were launched in September 1999 under the Central Motor Vehicle Rules 1989 and came into effect from October 1, 1999. These were tightened in 2005.

In 2009, the government ordered that emissions from tractors and construction equipment must comply with BS (CEV/TREM) III from April 2011, as shown in the table below.
