At one time I received an unexpected email from a shipping company that turned out to be legitimate, despite it having several red flags and being marked as spam by my email provider.
The point being, investigate and confirm before either condemning a message to the bitbucket or paying.
For example, if I received such a message, it would be ignored because I've not been near a toll road for well over a decade, but that might not be the case for every recipient, some of whom might not have paid their bill.
Reminds me of the "U.S. Post: you have a USPS parcel being cleared, due to the detection of an invalid zip code address, the parcel can not be cleared, the parcel is temporarily detained, please confirm the zip code address information in the link within 24 hours" message I got with the totally not suspicious domain "usps.com-service.webnw.top/us" and the unnecessarily confusing instructions "Please reply with a Y, then exit the text message and open it again to activate the link, or copy the link into your Safari browser and open it"
