A pilot program in Manitoba, Canada, will allow trucks to attach a smaller 6.5 meter trailer behind the normal 31.5 meter rig on the 750 km trip along Highway 6 between Winnipeg and Thompson. The smaller trailers are already used by trucks and buses on other routes but they have not been allowed on the northern route until now.
Although the rigs will not be able to increase the maximum weight allowed, they will be able to haul larger volumes of lighter cargo. In some cases, the change will enable trucks to haul the same volume of cargo in two trips that previously took three. Special permits are required.
