How do I create a car driving game using 8 directions where the car turns only in crossings?

If I press the down/up arrow in the middle of the street, the cars turn to left/right instead of going up or down the street (that I have to use to dodge the other cars). I want the car only turn to the left/right when it is trespassing a crossing. Is it possible?

Thanks

I don't really understand how your game is supposed to work. You need to post your project, or maybe a youtube video of a similar game.

Sorry. I don't started the game yet. I am just doing some tests to check if it's possible.

This is what happens when I press the UP and DOWN keys in the middle of the street or if I disabled de angle in the behavior.

I need the car go up and down the street and only turn to left or right with it is over the crossing. Like this:

Making the car to only turn on intersections is easy - just put an invisible square sprite there and ignore left/right keys if the car is not overlapping it.

But if you want the car to make a naturally looking 90-degree turn and enter its lane properly - this part may be tricky.

I already intended to use a sprite to check the keys in the crossing. Actually, the problem is that I cannot have the two options: turn (to right/left or left/right) and go (up/down or left/right) in the middle of the streets to dodge the other cars.

If I could disable/enable angle in this behavior using event commands, I will solve my problem, but I can't.
