Final answer:
When a lane is marked with a curved arrow and the word 'Only', it means that the lane is designated for a specific purpose or type of vehicle and other vehicles should not use it.
Step-by-step explanation:
When a lane is marked with a curved arrow and the word 'Only', it means that the lane is designated for a specific purpose or type of vehicle. The arrow indicates the direction that vehicles in that lane are supposed to go, and the word 'Only' indicates that other vehicles should not use that lane.
For example, a lane marked with a curved arrow and the word 'Left Only' means that the lane is only for vehicles turning left, and vehicles that need to go straight or turn right should not use that lane.
These markings are used to help regulate traffic flow and to ensure that vehicles are in the correct lane for their intended direction.
