Can you go straight in a dual left-turn lane?

[Helen]

You cannot go straight in a dual left-turn lane. Below is relevant information about lanes: 1. Dual lanes: Secondary and tertiary roads generally adopt dual lanes. For secondary roads in plain and hilly areas, when the mixed traffic volume is large and it is difficult to separate the slow lane, fast and slow lanes can be marked, but they still belong to dual lanes. Fourth-class roads should be designed as dual lanes, and single lanes can be used for sections with low traffic volume. For highways with a design speed of 120km/h, depending on the traffic capacity requirements, one-way two lanes, three lanes, four lanes, and bidirectional four lanes, six lanes, or eight lanes can be set up. 2. Speed: For highways and first-class roads with a design speed of 100km/h, when the traffic volume exceeds the capacity of four lanes, the number of lanes can be increased by even numbers. When a first-class road has a slow lane adjacent to the driving lane, the hard shoulder and earth shoulder parts of the roadbed width can be used as non-motorized vehicle lanes.
