QuoteTraffic Scotland reported that a dog had leaned on the controls of the tractor, which was in an adjacent field, and caused it to go through a fence and on to the M74 in South Lanarkshire at 8.15am on Wednesday. The tractor then crossed the motorway before crashing into the central reservation.
