Final answer:
On a freeway with four lanes in the same direction, you are generally permitted to travel in either of the two right lanes when towing another vehicle or trailer, but it is essential to verify local traffic laws.
Step-by-step explanation:
When you are towing another vehicle or trailer on a freeway with four lanes in your direction, traffic laws in many regions specify that you may travel in either of the two right lanes. This law is designed to help maintain smoother traffic flow and enhance safety on the freeway. The two right lanes are generally reserved for slower-moving vehicles, and this includes vehicles that are towing. It is important to always check local traffic laws, as rules and regulations can vary by location.
