One of these misunderstood road rules relates to lane merging.

Drivers can become annoyed and irate at other drivers in merging situations, not understanding the road rules that apply.

Here is a short explanation:

If the left lane is ending and the two lanes merge into one, the dividing line will end before the merge.

In this situation, Car B gives way to Car A , as Car A is in front.

The absence of the line shows you that you give way to the car ahead of you so they can easily merge in.

But if there is a dividing line all the way to the end of the lanes, it is called a zipper lane.

The dividing line tells the merging car they must give way to the main lane, and therefore control their speed to merge safely in an appropriate gap.

A common sense approach must be taken in lane merging as other drivers may not be aware of the road rules.

If someone is not going to give way and a potential collision may occur, you will need to slow down and avoid the collision with hazard perception skills.
