[True / False · Medium]

Answer: ✓ True

Explanation

On the main lane of an expressway, a vehicle that is equipped with a structure and equipment for towing and is towing a vehicle with a gross weight of more than 750 kilograms is required to travel in the leftmost traffic lane. However, where signs or markings designate which lanes to use, you must follow them. This is specified in the Rules of the Road, Chapter 7, Section 2, Driving Precautions, 3(7).

Exactly. Otherwise, it's leftmost — slower, safer, and out of the way of faster traffic.
