The COE quota consists of the following components: 1) Provision for 1.5% vehicle growth based on the vehicle population as at 31 December 2010, 2) Replacement COEs for vehicles de-registered between January and June 2011 and 3) Adjustment for over-projections of vehicle de-registrations in 2008/2009.
The next COE quota announcement, for the COE bidding period from February 2012 to July 2012 will be made in January 2012. The 1.5% vehicle growth rate, which is valid for 3 years from 2009-2011, is currently under review. The LTA will announce the growth rate from 2012 once the review has been completed.
