Following calls from OOIDA (Owner-Operator Independent Drivers Association) for a delay in the implementation of the EPA's 2010 legislation, Navistar has announced that it is ready to take a 'leadership role' in lobbying congress and the incoming administration. OOIDA is concerned about the introduction of new standards and technologies at such a sensitive time for the US trucking industry and the wider economy, and is seeking to delay the legislation and avoid a pre-buy situation.

Truck market analysts have indicated that Navistar's chances of delaying the adoption of 2010 rules are slim given the EPA's statements on any possible delays and the importance that President-Elect Obama has placed on the environment.
