What is the term used for a commercial vehicle's habit of swinging wide on wide turns?

Answer: A — Off tracking

Off tracking refers to the tendency of a commercial vehicle to swing wide on wide turns. This is due to the vehicle's longer wheelbase and larger size compared to smaller vehicles, causing it to turn at a wider angle. Choosing B, oversteering, is incorrect as oversteering refers to a vehicle turning more sharply than intended. Option C, understeering, is also incorrect as understeering is when a vehicle is unable to turn as sharply as needed. Option D, tailgating, is completely unrelated to the question and refers to a vehicle following another vehicle too closely.
