Final answer:
A lane marked with both a curved and straight arrow means drivers in that lane can either continue straight or take the next turn. It is important for drivers to signal their intention for safety and smooth traffic flow.
Step-by-step explanation:
When a lane is marked with both a curved and a straight arrow, it indicates that the lane can be used by drivers who intend to go straight ahead or take the next turn (left or right, depending on the direction of the curve of the arrows). Such signage provides flexibility for drivers and helps manage traffic flowing in multiple directions. If you are in a lane with these arrows, you should choose your position early and signal your intentions to other drivers to ensure optimal safety and traffic flow. Always follow the rules of the road and take into account the traffic conditions when deciding whether to go straight or turn.
