Is it possible to earn more money if I put some advertisement on my car?

Yes, it is possible. Many companies are willing to pay for driving around with their promotional ads. Actually, it is a straightforward and effortless way to make extra cash.

All you have to do is be over 18 years old, have a valid drivers license, and provide a car. I mean, you have to do some homework before you provide your vehicle to such companies. Usually, it is not about thousands of dollars but 200-400$ per month or so. There are many scammers in this field, just like any other field. I know that Smartek in Canada offers a good paycheck and has friendly terms of the contract. They provide digital LED screens for digital taxi top advertising that assemble on top of a vehicle and runs ads. An excellent way to make extra backs if you are a taxi driver since you drive all day around anyways. Plus, LED screens are on the remote control and dont consume much energy. The company takes care of installing the screen, and engaging ads, all you have to do is drive your car as usual.
