Despite the overall ease of controlling a car, the statistics still show many drivers get into accidents. Although it’s not always the fault of the person behind the wheel, people can often trip over even the most basic rules.

As such, knowing road regulations becomes vital in maintaining road safety. Knowing this could help you keep yourself and your passengers safe. And even though road signs may seem like common knowledge to some, newer drivers may struggle, and thus it becomes essential to cover the topic in-depth.
Let’s start with an inductive approach and answer the question in the title. To begin with, it’s crucial to know that all rectangular-shaped signs show some kind of information to you. They can warn you about upcoming junctions, tourist attractions, services, or diverted traffic. However, there are certain differences depending on what type of rectangular sign is before you.
Depending on the way they are oriented, you can distinguish between two main types:
You must obey all vertical rectangular signs, but horizontal ones are not necessary for driving. This answers the question in the title, but there are more signs beginners should know about.
Rectangular signs are not the only ones you can spot on the road. There are a couple more out there that will warn you and regulate your movement on the road.
Circular signs are used to give orders and usually hint at something you must or must not do. You should never ignore them, as doing something against traffic laws could lead to fines and license suspension. Triangular signs warn drivers about upcoming hazards or changes in the traffic flow.
The only sign that has a unique shape is the stop sign, which is an octagon. It was done deliberately for the drivers to immediately notice and recognize it. Plus, it is designed similarly across the globe, which should only help drivers with a year or so of experience.
With shapes out of the way, colors should be the next priority. Here you will quickly notice that they effectively serve their purpose and help easily distinguish between instruction and general information.
All in all, you can find signs of the following colors on the road:
The only real exception to the rules here is the color yellow. It is used to make the signs more noticeable as they divert traffic. As with the stop signs, it comes in handy in all situations and helps avoid road accidents.
When driving, it is crucial to be cautious and pay attention to all the road signs you are passing or about to pass. Rectangular signs can either give directions or provide general information about the area. Circular ones give you instructions or orders, while triangular-shaped ones warn you of any upcoming hazards.
Lastly, they have different colors to help drivers distinguish their purpose, with yellow being the major exception to diver traffic. Here it’s much better to dig into the theory and familiarize yourself with the sign symbols, as color is just meant to grab your attention. After some practice, beginner drivers will get the hang of it and quickly recognize any sign.
