zt 官方解释

Passing on the right can be more dangerous than passing on the left. If you are driving in the left most lane with a slower vehicle in front of you, wait for the vehicle to move to the right. Do not suddenly change lanes and pass on the right; the driver in front may realize you want to pass and move to the right at the same time you do.
