Can I go straight when the green light is on in a variable lane?

[SanEmersyn]

You cannot go straight when the green light is on in a variable lane; it mainly depends on the road markings. Correct lane-changing method: Before changing lanes, you must turn on the turn signal, observe the vehicles ahead and behind, ensure a safe distance, steer gently, change lanes quickly, and avoid crossing multiple lanes. Pay attention to arrows or signs if there are guide lanes. Precautions for changing lanes: First, observe and assess the traffic conditions on the sides and behind your vehicle, then turn on the turn signal. Reconfirm that there are no vehicles overtaking from either side and maintain a safe distance in the lane you intend to enter. Steer smoothly into the desired lane and then turn off the turn signal. You should only change to adjacent lanes. If you need to move to a farther lane, first change to the adjacent lane, drive for a while, and then change to another lane. When encountering an intersection while changing lanes, choose the lane based on the direction you need to go and enter the guide lane according to the directional arrows on traffic signs. If you encounter an obstacle while changing lanes, change lanes in advance to prevent collision accidents caused by forced lane changes. The technique for changing lanes while driving emphasizes not being too slow when turning left or right. Driving with the wheels on the lane line for a long distance can affect other vehicles. The optimal distance for changing lanes is between 50 to 60 meters.
