We propose single jet triggers for CMS and simulate an analysis of the dijet mass distribution based on these triggers. A full trigger table for single jets is developed, including thresholds and prescales at L1 and HLT. The evolution of the table with instantaneous luminosity is presented, and the rates expected from the trigger are estimated. We present an analysis of the QCD dijet mass distribution that would result from taking data with this trigger. For three different samples of data corresponding to 100 pb^-1, 1 fb^-1, and 10 fb^-1 we estimate the expected statistical and systematic uncertainty on the cross section versus dijet mass
