That sounds like your city is hitting the vehicle limit. You can check that with a mod like CSL Show More Limits.

To deal with that you will need to provide more public transport, so your citizens aren't driving everywhere. The more mass transit, the less cars on the road, which means more vehicles for other things.

Using cargo rail to distribute goods and raw materials is another way to lower vehicle usage. Having a cargo train station in every industrial area connected to an internal track, that also connects to larger commercial areas is a good way to get things moving on trains instead of trucks, which means fewer vehicles in use overall.

Definitely check the vehicle limit. I might be completely wrong, but it's so easy to check and there's not really any point in us wasting time doing more troubleshooting if that's it. So best to exclude it as a cause now before we dive in deeper. :)
