Making fun of someone else's stupid thread. The OP probably won't get the joke anyway. Well done anyway, Darkangel.

Really no need to comment on that considering there is a little report bottom near the top that allows you to tell that directly to the CT and allows them to fix the issue much quicker.

I don't think you can use a siren on a civilian car slot, unless there is a line in the vehicle data that defines if it is an emergency car or not.
I've checked through the model flags in the handling file, none of them say "IS_EMS" etc.
 
As a result I can only conclude that this feature is hard coded into the game (I may be wrong though)
 
Your best option then is to replace an EMS vehicle with your new fire truck and edit all the handling lines yourself. For example a guide I just read teaching you how to do so, replaced "police3" in GTA IV (which is a registered but unused slot, due to EFLC using it) with the new firetruck.
 
Otherwise you will just have to pretend your admiral car you turned into a firetruck has a siren. I imagine someone sitting there making fire truck noises while playing GTA IV lol.
 
Alternatively, you could change the horn for that car I guess? But then you will have all the admirals you replaced with fire trucks blaring sirens at silly times.

Anyone else having the problem of 99.9% of traffic stops resulting in a pursuit?

all ready said it! ha-ha :)

I see it. Interestingly I never noticed the sign until I saw this topic...
Maybe this topic made the sign appear? LOL
 

It's so obvious..
it's celebrating Independence Day for Mongolia!
