Final answer:
The left or "fast" lane on a highway is called the Number 1 Lane, especially in areas where vehicles drive on the right side of the road.
Step-by-step explanation:
The left or "fast" lane on a multi-lane road or highway is commonly referred to as the Number 1 Lane. This is the lane that is furthest to the left when driving in countries where traffic moves on the right side of the road. In a standard three-lane freeway setup, lanes are typically numbered from left to right with the leftmost lane being Number 1 and the rightmost being Number 3. The Number 1 Lane is often reserved for faster-moving traffic and for overtaking slower vehicles in the other lanes.
