Isn't this a waste of taxpayer dollars?   Who decides where to locate signs along our highways? Couldn't we have more safety and directional signs along our roads?   Why do the speed limits vary on different parts of the freeway system?   What’s the difference between highways that carry the letters “US,” “I” and “M”?   Where can I get information on current road conditions for Michigan roads?   How many miles of road does Michigan have?   Where is Intelligent Transportation Systems (ITS) located?   Who do I contact for general questions about Michigan's Heritage Route Program's nomination and designation process? How can I obtain the application forms for nominating Heritage Routes?   Who can I talk to about trucks speeding or tailgating, or other truck safety issues?   Why are the weigh stations on the interstates closed so often?   I have heard that Michigan truck weight laws are the most liberal in the nation. Is this true?   Who is responsible for plowing snow on state highways?   Does MDOT issue overweight permits that would permit the transportation of overweight ocean containers?   I have seen big symbols (X, +, V, T) painted along state trunklines. What are these symbols, and what are they used for?   What causes potholes?
