Must let the vehicle go within one lane + change lanes where permitted + signal + rudely go to the right lane + motor vehicle goes left lane + lower speed go to the right.
Answer 2 is incorrect because lower speed goes to the left.
On a road with multiple lanes for vehicles traveling in the same direction, separated by lane markings, the vehicle operator must keep the vehicle in one lane and change lanes only where permitted; When changing roads, there must be a warning signal and ensure safety.
Vehicles participating in road traffic moving at a lower speed go to the left.
On a one-way road with lane markings, rudimentary vehicles must travel in the innermost right lane, motor vehicles, special-use motorcycles travel in the left lane; road traffic moving at a lower speed to the right.
