I would Get a copy of the communication with the glass people and print it out and put it in the truck .Any reasonable law enforcement officer will see you have done everything possible and I would sincerly doubt you would get a citation
Likely his only vehicle, has to work to make the payment and it's a fix it ticket, not a felony offence.
No I really don't have a choice. I have to drive a lot for my job and can't just get rides to here and there. I only have one vehicle, so I don't have a choice, now do I?
You'd be surprised to find out that traffic cops often do not have more to worry about than a cracked windshield and a chance to sniff the inside of your vehicle. Think about keeping something in your truck that verifies that you're working on it.
Yes, it is. Especially if it is your only vehicle and you have to drive or you don't eat. Try to get over yourself and look at reality.
You could always loan him yours.
As far as a citation only a badge heavy law enforcement officer would write you a cite .
I'm not sure that a cracked window makes it "unfit for purpose." Ideal, no. But "unfit" seems like a stretch.
In most situations it's likely not an issue, but technically speaking automotive glass is a safety feature. In an compromised state the glass could fail to protect occupants the way it was designed to.
We bought the new model civic in 2015. Windshield got busted. Waited months, as all windshields were allocated for production. Could not get aftermarket brand at the time, due to being a new model and the first civic with insulated front glass. Dealer bought the car back from me at same price, as it was not drivable.
Just carry some sort of documentation that shows you are in the middle of the repair process and you will be fine if you get pulled over for it.
