Hot Exhaust Light after exiting freeway and smoke

The truck unfortunately didn't come with a pyrometer. If it were my truck I'd have one. It is fitted out with more guages than most. 17 to be exact. There is one blank spot though and that's probably where the pyro would have been I guess lol.

Mostly I'm worried about there being a fire associated with the smoke. I have a dog and a cat so I'd prefer not to have them burn up in the truck while I'm away for a few minutes after coming off the highway. And I know that there is a group out in Cali blaming truck fires off of the DPF. So that's probably what's got me worried. The other issue is this truck doesn't tell me it's regenning going down the road. So how am I supposed to know that it's in the middle of that process when I exit the highway? Is there a way to know?

It only "asks" for a regen if I've been idling for more than 12 hours. Other than that I can't tell you how often it's doing it.

 

I'm wondering if I need to describe the smoke. It's like a light white smoke, not thick at all and it only occurs if I get this light.
