Recaptcha is the actual frustrating part.
I have an advice for you: try to make it longer, by taking at least 1 second between clicking on each image, otherwise you may be detected as a bot and even if you
selected the right images, you won't be authorised.
That being said, I never select the poles and only the parts containing the proper traffic light.
The most important part:
If one pixel of the traffic light expands on another selectable part, make sure to click on it.
OP, here is the true solution you need into your captcha problem. Just follow every bit of his direction to the letter. I used to get frustrated too until I discovered this trick.
