Terrible Don't buy

I couldn't get beyond selection of California as the problem is that I'm trying to get to Utah. Made 10 attempts which is too much.

Developer Response ,

This was fixed with an update in the past that allow you to manually select the 'Get Laws' button before it would automatically go to the laws screen.

Trailer law?

At least for my state 1/2 the stated laws were wrong after checking with the DOT from my home state NM. Makes me wonder if I can trust this for cross country driving ?

Developer Response ,

We are sorry you feel this way. We actually went back and again verified/adjusted the laws when they were updated.
