Why Are Commercial Taxi Number Plates Written in Black Letters with a Yellow Background in India?

Have you ever noticed a taxi, auto-rickshaw, bus or any commercial vehicle on Indian roads? If you have seen one, then you all have noticed that all commercial vehicle taxi numbers are written in black letters with a yellow background, and on normal cars’ number plates, you all see their number plates are written in black letters with a white background.

Then, why are commercial taxi number plates written in black letters with a yellow background in India?

Let’s explore this article and learn all the reasons in detail.

What Does a Yellow Number Plate Mean?

A yellow number plate generally indicates that the vehicle is being used as a transport vehicle. This includes many vehicles that carry passengers or goods for commercial purposes.

For example:

• Taxis

• Commercial cars

• Auto-rickshaws

• Buses

• Commercial goods vehicles

Why Are Commercial Taxi Number Plates Written in Black Letters with a Yellow Background in India?

Under the transport or commercial vehicle rules under THE CENTRAL MOTOR VEHICLES RULES, 1989, all commercial taxi number plates must be written in black letters with a yellow background in India.

As we know, India has a huge number of vehicles on its roads. So, to easily recognise and identify the cars for the public's convenience, black letters with a yellow background were chosen for all commercial taxi number plates.

Why Are the Letters on the Number Plates Written in Black Colour?

The letters and numbers are kept black against the yellow background so that the registration number can be clearly seen.

The registration number is very important because it is the vehicle's official identification mark. For transport vehicles, the government rules specify black characters on a yellow background. 

This also makes the number plate easy to notice from a reasonable distance.

What About Private Cars?

Private vehicles have a different colour combination. For normal non-transport vehicles, the registration mark is displayed in black on a white background. 

So, you can remember it simply:

How many other countries use a yellow background and black letters on commercial vehicles?

Many countries use a yellow background with black text specifically for commercial, business, or public transport vehicles:

• Denmark: Denmark specifically uses yellow plates with black lettering for commercial vans, trucks, and goods vehicles.

• Vietnam: Yellow plates with black characters denote commercial transport vehicles, including taxis, buses, trucks, and ride-hailing cars.

• South Korea: Business and commercial vehicles (such as taxis, buses, and commercial trucks) use yellow registration plates with black lettering.

• Colombia: Taxis, buses, and all commercial transport vehicles carry yellow plates with black numbers/letters.

• Indonesia: Public transportation and commercial passenger vehicles traditionally feature yellow license plates with black text.

• Sri Lanka: Public transport and commercial passenger/goods vehicles use yellow license plates (primarily on the rear, or as standard for commercial registration).

• China: Large commercial vehicles, heavy trucks, and buses use yellow license plates with black characters.

Note: There are many others countries are also there, who uses a yellow background and black letters on commercial vehicles

So, the next time, whenever you all see the vehicles number plate in yellow background and the letter are written in black colours, it is commerical vehicles, and why this colours combiation is differently from the other private vehicles to recognise easily between private vehicles, and commercial vehicles.
