Yes, you can earn money by just drawing blocks over cars and street signals.
This website is called Remotasks.
You can simply search on google remotasks and it will appear on the first.
It will appear like that and you have to click on the first site or I am giving you the link over here to sign up.
But there is one thing you have to keep in mind that you have to log in with facebook containing email address, if your facebook doesn't contain an email address then it will show the error.
And after completing your registration simply complete the tutorial by which you will get over 2$.
So, Best of luck
