One possible area of concern the proposed “truck only” lanes raise is the possibility of the lanes leading to the introduction of so-called “truck platooning” or perhaps longer combination vehicles (LCVs).
“Truck platooning” is the practice of two or more semi-trucks driving in a tight line formation together. The lead truck typically handles navigation, with the trucks in the rear communicating at all times with the lead truck.
Proponents of truck platooning say it saves time, money, and emissions. Opponents say that trucks driving closely together have the potential to cause catastrophic accidents.
The truck only lanes could also prompt lawmakers to change the rules about LCVs. Instead of a truck platooning situation, where multiple trucks travel in a group, an LCV involves a single semi hauling multiple trailers — typically two, sometimes three.
Advocates for truck only lanes say the lanes could be a good solution for the truck driver shortage that has been making it difficult for carrier companies to find drivers for their trucks. They argue that opening up lanes for truck traffic makes it possible for trucks to platoon — or for truckers to drive LCVs — without worrying about maneuvering around other types vehicles on the road.
