I don't think you can. It's a shame! But you can use a police car and turn the sirens on by pressing the right analog stick; cars will move out the way.
In GTA and in Saints Row, there are no turn signals, you just have to turn without them and hope no-one crashes into you!
You can create anyone you like
No.
yellow
no
Yes you can get a knuckleduster. You have to find it at your saints hideout where one of the shanties use to be.
don't use cheatcodes and you will get achievements
You can't!
It depends, if its for xbox 360 on saints row 1 it is the right analog stick and on saints row 2 it is the left and you have to press them down if its for any other platform i do not know.
You could be hitting the flash feature on the turn signal arm when you use it.
We could use a little more info here. The turn signal light? In front? In the rear? The turn signal switch?
Bad flasher unit or turn signal switch
