The American Trucking Association is currently pushing to increase the number of longer-combination vehicles (LCVs) allowed on the nation’s highways – it’s all part of the organization’s initiative to green the industry. But the push is drawing criticism and sparking debate from others, including some truck drivers, who are convinced LCVs may do more harm than good.

Only 23 states in the country allow LCVs on their roads, typically those with less densely-populated areas (California has banned them altogether). Many claim triple and even double trailers are dangerous and comprise safety, especially in areas where there are more drivers on the road.

But the ATA argues that LCVs have a decent safety record – better than five-axle semis. In fact, they are the most regulated vehicles on the road; drivers of such vehicles must have special permits to operate them, they are only allowed on certain roads, and they must get off the road during inclement weather. Furthermore, truck driving companies don’t take any risks when it comes to operating LCVs – they use only their best and most experienced drivers.

The ATA claims that having more LCVs on the road will increase fuel efficiency, shrink truck congestion, and reduce pollution since it will result in fewer trucks on the road.

Do you think LCVs are good for the environment (and the industry) or comprise safety on the road?
