Recently, I discovered a strange phenomenon - ten online car-hailing vehicles on the road, eight of which were facing a glowing advertising screen. Can this thing really make money while driving? What newbies are most confused about is: Where should I install the screen to prevent it from being illegal? Last week, I saw the traffic police stop a car with a screen stuck to the windshield, and the 200-yuan ticket was opened as soon as possible. Today I will take you to find out the tricks and ensure that you can earn advertising fees without breaking into the mine!

Traffic lights are stipulated by law

Make the point first! According to Article 11 of the "Technical Conditions for Motor Vehicle Operation":
​​Allowed installation area​​：

1. Roof (height not exceeding 30cm)
2. Trunk lid (area ≤0.3㎡)
3. Doors on both sides (≥50cm from the ground)

​​Absolutely forbidden area​​：

• Inside/outside the windshield (directly deduct points if affected by sight)
• 10cm range around the license plate (12 points are missing in the cover license plate)
• Engine cover (reflective interference with other drivers)

There is a real case: A car owner in Chengdu installed a 0.5㎡ screen on the roof, and earned a net profit of 3,800 yuan after receiving 6 advertisements per month. The key is that he used a detachable bracket and could be removed in five minutes during the annual inspection.

Comparison of advantages and disadvantages of four installation solutions

Focus on the roof plan: Now the mainstream is fixed with neodymium iron boron magnet, the suction force reaches more than 180kg, and the 120km/h speed will not drop. But remember to choose a style with cushioning pad, otherwise the sudden brake may scratch the paint.

Equipment purchasing guide

​​Three essential elements for qualified car screens​​：

1. ​​Intelligent brightness adjustment​​: During the day, it will automatically drop below 800cd/m² at night (anti-glare)
2. ​​Power supply safety​​: Supports 12V direct plug-in of cigarette lighter (power <100W), do not change the original car circuit!
3. ​​Quick disassembly​​: With quick disassembly interface (10 seconds to uninstall the screen), convenient to restore the original car status at any time

Beware of these dangerous designs:
▸ Style with sharp frame (may become a weapon in an accident)
▸ Installation method that requires hole drilling and fixing (depreciation will be depreciated if it destroys the body)
▸ Power supply without overheating protection (in the car at high temperature of 70℃ in summer, it will spontaneously ignite)

Potential pricing rules

Teach you how to calculate the account clearly:
​​Basic quotation = screen area (㎡) × 3 yuan/day​​
​​Value-added part​​：

• Average daily driving of the vehicle > 6 hours + 20%
• Passing through the commercial area +30%
• Supports GPS positioning statistics +50%
• With interactive function (scan code to draw, etc.) +80%

For example: online car-hailing with a 0.3㎡ screen, you can go to the airport three times a day, and your monthly income can reach: 0.3×3×(1+20%+30%)×30=1755 yuan. This is much more cost-effective than hitchhiking subsidies!

Annual inspection clearance secrets

This is the safest way to operate under the new regulations in 2023:

1. Prepare three parts in advance:

   • Car electronic products 3C certification
   • Installation agency qualification certificate
   • Advertising content review form

2. On-site inspection focus:

   • The screen does not flash when powered on (shoot in slow motion mode of the phone)
   • Power off immediately after the engine is turned off (delay > 3 seconds is considered unqualified)
   • The frame temperature is less than 60℃ (use infrared thermometer)

3. Alternative plan:
   Spend 500 yuan to find a scalper? It’s better to spend 150 to buy a quick disassembly bracket, and it’s more reliable to disassemble and assemble yourself in ten minutes.

​​The editor tells the truth​​：
Nowadays, installing screens on cars is like wearing masks - wearing them right is a protection, while wearing them wrong is a burden. Focus on three principles:​ ​Don't block your sight, don't change your body, don't answer illegal advertisements​​. I have seen too many people buy miscellaneous screens with cheap prices, but the advertising fees they earn are not enough to pay fines.

There is a new trend recently: smart car owners specialize in time advertisements for surrounding shops. For example, broadcast promotions for breakfast shops in the morning, change to fast food shops at noon, and accept KTV advertisements at night. If your screen can play different content in time periods, it is not a dream to double the quotation directly!
