Ok, I went through the game screens, I went through the manual, all with no luck. I've seen drivers in-game running around with their 4-ways on (hazard lights). How are they doing that?

It is in the documentation.

LFS Folder\docs\keys.pdf

7 - left indicator
8 - right indicator
9 - both indicators (all)
0 - turn off

Thank you. Figures, looked everywhere but THERE.

Well, then that isn't everywhere Oh well have fun. The hazard lights come in handy sometimes, especially when you've crashed and and are slow on the track.

But..... some people put them on for the hell of it, oh well

Quote from thisnameistaken :

I think that's to let you know that they are hazards even with a healthy car.

I think those types of drivers are GREATER hazards with a healthy car. If it's banged up the suspension's all out of whack and they won't get far, and certainly won't get there quickly.

Just watch out for anyone driving a car that looks like this.
