Are Double Trailers A Bigger Risk?

Double trailers, as their name suggests, are two tractor trailers hitched together on the same cab, one after another. These vehicles provoke much debate and controversy, with some claiming they make roads safer and some suggesting double trailer trucks are an added risk on the roads.


Advocates for double trailers – including those trying to convince Congress to change the rules to get more of these vehicles on the road – say double trailers are a good thing because:

  • They can increase safety by distributing heavy loads over a larger surface, potentially reducing the risk of accidents
  • They can reduce fuel use and carbon emissions, potentially making them a greener choice
  • Reduce costs by letting trucks haul more cargo
  • Reduce the number of tractor trailers on the road (and therefore reduce accidents) by allowing more to be shipped with every truck
  • They save truck drivers time (by allowing for two different loads to be delivered to two different destinations with no extra time for reloading) potentially reducing truck driver fatigue

Critics and some truck drivers do not think double trailers are safe. In fact, some people think double trailers are more dangerous because:

  • They mean heavier loads, which means more wear and tear on the roads, which in turn can lead to collisions caused by poor road conditions
  • These vehicles mean even larger blind spots
  • They can scorpion tail, whereby the second trailer crashes into cars in lanes alongside the truck

Some truck drivers refer to double trailers as “widow makers” or “wiggle wagons.” In addition to proposed plans for more lenient rules for double trailers, some are also seeking to increase the size of individual trailers to 33 feet, which would allow for even more cargo on the roads. Some safety experts think increasing the size of trailers and allowing double trailers cold potentially be even more dangerous, since larger trailers may be more prone to rollover incidents while double trailers can cause crashes. Of especial concern is what would happen if a larger trailer swung outward into oncoming lanes in a scorpion tail – the larger size (if the larger sizes were approved) would potentially cause more damage.

There is some compelling evidence to suggest double trailers could be a danger. Studies by the U.S. Department of Transportation concluded that trucks with multiple trailers had fatal crash rates 11% higher than single-trailer trucks. Independent studies from MTIC in 2013 and 2014 also concluded that double trailer trailers have a fatality rate 11% higher than that of trucks with only one trailer.
