==Explanation==
{{incomplete|Created by a trapped driver - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic depicts a trio of road signs that provide legal instructions that are, in combination, impossible to follow: "Do not enter" precludes passing the point of the sign, the No-U-Turn sign precludes turning around, and the "No Stopping Any time" sign precludes halting before the sign.  A driver approaching this sign combo would seemingly be forced to violate at least one of the three. However, the driver could technically put the car in reverse or slow down exponentially to comply with all three signs.

The title text mentions something similar: you cannot be slower than 45 MPH while being faster than 65 MPH, which is obviously also impossible.{{citation needed}}
