abstract="In 1992, voters in Oregon defeated a referendum that would have banned triple trailer operations in the state, suggesting that voters perceived benefits from triple trailer operation. This study uses a contingent valuation methodology to obtain an estimate of those perceived benefits. Results indicate annual benefits from triple trailer operation of approximately $130 million per year in Oregon.<p />",
