Final answer:
The right lane in a multi-lane roadway is used for slower-moving traffic and facilitates entering or exiting the road.
Step-by-step explanation:
In areas where there are three or more lanes travelling in the same direction, the right lane is typically used for slower-moving traffic and is the designated lane for vehicles to enter or exit the roadway, such as for getting onto or off of exits and entrances. On highways, the left lanes are commonly used for passing or for faster traffic, while the right lane is for driving at the speed limit or below. It's important to remember that this may vary depending on local traffic laws and patterns.
