To facilitate planning for a motor vehicle emissions inspection and maintenance program in Wayne, Oakland, and Macomb counties, the Transportation Research Institute carried out a statewide mail survey of Michigan drivers. More than half of the respondents (56 percent) were favorable to setting up an emissions inspection program in the three counties. As for program features, respondents tended to favor an owner choice between an annual exhaust emssions test an an annual certified tune-up, and they strongly favored a registration enforcement method over a sticker enforcement method. Questions on misuse of pollution control equipment indicate that over 10 percent had removed a catalyst converter and over 8 percent made use of leaded gasoline in unleaded vehicles at least occasionally. This was more prevalent among the half of the sample who usually perform their own maintenance.
