The public should urge their lawmakers to oppose efforts by FedEx and UPS to increase the national twin-trailer standard to 33 feet from 28 feet per trailer (Letters, Feb. 6). Granting this corporate giveaway will permit longer trucks on our roads, which will erode safety and adversely affect our nation’s infrastructure. My own experience informs my serious concerns with making trucks even longer. In August 2010, my wife, Susan, was killed and my sons, Peter and Matthew (who is now permanently disabled), were injured in a crash after a truck driver operating a triple tractor-trailer fell asleep and crashed into the back of their vehicle. Unfortunately, crashes in which a truck rear ends a passenger vehicle have skyrocketed, increasing 82% from 2009 to 2015, as calculated by the Truck Safety Coalition. Introducing trucks that require an additional 22 feet to brake will exacerbate this trend. According to the U.S. Department of Transportation’s Comprehensive Truck Size and Weight Study, any reduction in truck-vehicle miles traveled would be wiped out within one year by increases and shifts in freight transportation. The study also found that permitting double 33s would incur a one-time cost of $1.1 billion to strengthen and replace more than 2,000 bridges. This finding dispels the claim that the “trucking industry foots the bill. Instead of demanding longer trucks that require a greater distance to stop, companies should look to technologies, such as automatic emergency braking, speed limiters and underride protections to enhance safety, protect our infrastructure and improve their bottom lines.
