On the Subject of Signal Driveway

Yes, the mod DOES instruct you to go run over the duck.

On the module is a stick person holding a flag, three traffic lights on the top, and three buttons on the side.

Looking at the flag, determine what type of signal it is representing using the three tables below.

Green
Yellow
Red

The lights on the top of the module will show separate letters. According to the column of the flag design, look at the letters of the other two colors.

Take the A-Z alphabet, and click the button on the right that is between the two letters obtained in the last step. (Example: Letters are Q and X, any valid letter is R - W).

If there is not enough of a gap (A and B or two As, for example), choose one of those two letters present otherwise.

Repeat this process for five stages to solve. If you click the wrong button, you will strike and restart at Stage 1.
