RIGHT-HAND & LEFT-HAND TRAFFIC
I assume that most of us have driven a car, or vehicle should I say, and some of us may have even started driving illegally (i.e. without an official license). Well, in this post, I am not going to touch on that subject, I am going to focus more on traffic flow. Traffic jam may sound like an interesting topic (I think), but I'm sure that many people have known about the implications and the causes of those incidences. Instead, I am going to talk about right-hand and left-hand traffic.
So, what do those two terminologies mean?
To put in rough, technical terms, it means that which side of the road do people drive in a specific country. Take a look at the following examples:

The picture above is an example of a left-hand traffic. As you can see, the cars on the left side of the road are driving upward. You can even tell the same when you look in the opposite direction.

The picture above is an example of a right-hand traffic. As you can tell, the cars on the right side of the road are driving upward. Pretty obvious isn't it?
The country that I live in, Malaysia, is one of the few countries that uses left-hand traffic.

The map above illustrates the countries that apply a certain kind of traffic flow. The countries in red use right-hand driving, whereas the countries in blue use left-hand driving. Visually, a majority of the world use right-hand driving. I was in awe when I saw this diagram for the first time.
Strangely enough, a majority of those blue countries belong to the Commonwealth of Nations. So could it be that when the British colonized these areas, they wanted to use left-hand driving so that they could be labelled as "one-of-a-kind"? I am going to let you reflect on that.
Now comes the part where I wanted to portray about the most in this post. Some of us have been to other countries by car. Example, if I were to enter from Malaysia to Singapore, I have to pass through an immigration border of each country. Once the process is done, it is back to on the road as usual. But thankfully, both Malaysia and Singapore drive on the left side. But have you ever wondered what actually happens when we have to change from a left-hand road to a right-hand road at the border?
I actually reflected on this question for years, but thanks to Internet and research, the mystery that was buried in my train of thought has finally uncovered.
There are 4 known ways to switch traffic from one side to another.
1. Using traffic lights

This is the Second Thai-Lao Friendship Bridge. This picture is taken in Thailand where the bridge is heading to Laos. As you can see, the traffic lights play a role of controlling the traffic change so that no accidents or collisions occur. Well, how do they work?

Let's zoom in a little.
See that little intersection there? That's how the traffic is controlled.
2. Crossover bridges

This is the Lotus Bridge that connects Macau and mainland China. This is pretty much self-explanatory. Another example:

This is the Takutu River Bridge that connects Guyana and Brazil. Like the Second Thai-Lao Friendship Bridge, the roads intersect. But if you take a closer look, a road overlaps the other, so no collisions can occur.
3. Intersecting Roads
I couldn't find the images for this or Google Earth wasn't much help to, but the areas are Man Kam To that links China and Hong Kong, and Portas do Cerco that links China and Macau. Basically, these places use roundabouts or other one-way traffic system.
4. Signposts and directions only
These areas are commonly found in places where there are low traffic volumes.
Examples include:

Remember, always drive safe, and always keep your eyes on the road (or eye if you're a cyclops).
