Interstate Speed Limit Compact

[roadfro]

Maybe the states should work together so that "State A" puts up W3-5's to denote the lowered speed limit at the state line ahead in "State B" instead of moving the imaginary line further down the road. I see that is being currently done in a few places.

This I can get behind. The concept of the speed compact could instead be that a state agrees to allow/require an adjacent state to post an appropriate W3-5 sign where speed limits drop 10mph or more at the state line.

E.g.: If the hypothetical speed limit on I-15 southbound is 75 in Nevada and 65 in California, then NDOT approves for Caltrans to post the appropriate W3-5 warning signs in Nevada just before crossing the state line into California. That sign would be maintained by Caltrans (or NDOT compensated by Caltrans for said sign), and updated/removed as necessary if the speed limit in California ever changes.

Regarding interstates, I don't think a uniform system could be implemented because there are so many different variables and unique situations that there would be so many exceptions to the rules made. However, I do think that all states should consider increasing their speed limits, this would be my plan in regards to my state, Kentucky for limited access freeways:

Plan A (the four 5's)

• 55mph: Urban areas and some mountain areas (Louisville urban I-64, 65, 71, 264; Covington/Cincinnati urban I-71/75, 275, 471)
• 65mph: Suburban areas (Louisville Suburban 65, 64, 71, 265; Covington/Cincinnati suburban I-71/75.)
• 75mph: Exurbs; Rural, but highly traveled interstates; rural but low traveled interstates that are not safe at the next tier (Exurbs: I-24 near Paducah; Louisville I-71, 64, 65; Lexington I-75 and I-64; High Traveled Rural Interstates: I-65, I-71, and I-64 between Louisville and Lexington. 
• 85mph: Rural, but low traveled interstates and other limited access highways (I-24, I-69, all of the parkways bar the Mountain and Rodgers parkways. 

Plan B (The three 0's):

• 60mph: Urban and mountain areas
• 70mph: Suburban Areas
• 80mph: Exurbs and rural
