Road Lines – Yellow and White Lines Explained
Have you ever thought about road lines while you were stuck in a traffic jam? You’ll be looking at different white and yellow lines and wondering why they’re there. We’ve always been told that these lines are structured to regulate traffic and cars. But how?
If you’re here because you’ve just received your license or you’re asking out of curiosity, I’ll answer all the questions you have in mind.
The First Road lines
The first road lines are traced back to both the US and UK. In 1911 in the US, Michigan Edward insisted that there must be solid lines on the road to regulate traffic.
He took this action after he saw a milk wagon leave a white trail along the road. Later, a painted center line was done along Trenton’s River Road in Wayne Country.
While in Europe, the very first white lines are traced back to 1918 in the UK. Then in 1926, these markings were recognized as a part of the road safety protocol. Later in the 30s, these lines worked as stop signs and warning signals to direct traffic.
On the other hand, yellow lines made an appearance in the 1950s. Then dashed lines were introduced in 1956.
Road Lines in the 21st Century
As the years pass and the number of vehicles increases, road lines become more essential. They play a vital role in regulating the paths of cars to avoid accidents.
Therefore, it’s mandatory to be aware of these lines, whether you’re an experienced driver or you’ve just received your license.
There are multiple road lines available, and each has a distinct meaning and function. There are white and yellow lines. Some are straight, and others are dotted.
I shall cover each in detail below.
What Do Yellow Lines on the Road Mean?
Let’s start by understanding what the yellow lines are and their meaning. You’ll notice 4 different yellow lines, these are:
- Double solid yellow lines in the middle of the road
- The dashed yellow line in the center
- A mix of solid and dashed yellow lines in the middle
- A Yellow line on the left side of the road
What Do White Lines on the Road Mean?
Let’s move to the white lines that appear on the road. White lines separate traffic moving in the same direction and are noticeable on one-way streets.
How Are They Painted?
If you’re thinking about how these lines are painted, you’ll find this part interesting.
The paint used is made from thermoplastic resin, mixed with titanium dioxide pigment, and mixed with ting glass beads. On main roads, this is applied using vehicles under computer control.
Smaller roads require more attention and effort. The paint is applied from a pram that’s heated to keep the paint color solution in its liquid form.
Although this might seem like an easy job for you, it requires some special skills. The lines need to be painted precisely at the right rate, the right thickness, and width.
The paint is made rigid and durable to face whatever nature gives from rain, snow, extreme heat, and sun.
Road lines have great importance in regulating traffic. They play a fundamental role in reducing the number of car accidents.
Every kind of vehicle should respect and follow these drawn lines. These lines guide traffic on all roads ranging from back country lanes to the busiest city roads.
That’s why you should have good knowledge of each line, and you should abide by the rules for your own safety and others.
