Your Guide to Driving Fast - Speed Limits Throughout the US and Canada

This is a travel blog, and road trips are my #1 hobby.  If you share a love of the road, and more importantly, of getting where you want quickly, I have put together for your viewing pleasure a complete list of speed limits by state and Canadian province (Canadian speed limits have been converted from kilometers per hour to miles per hour).  Many of these I have personally verified by physically driving there, and these are accurate to the best of my knowledge.

DISCLAIMER:  While I have made every effort to verify the accuracy of this information, it is not guaranteed.  Furthermore, this is not intended to be nor should it be construed as legal advice.  If you have any questions about traffic laws specific to a particular jurisdiction, you should consult a qualified traffic attorney.

Updates:  8/22/13 (Illinois - interstates raised to 70)
9/28/13 (Ohio - raised to 70 on selected non-interstate limited access freeways)
11/25/13 (Pennsylvania - interstates raised to 70)
2/10/14 (Manitoba - research indicates that maximum speed is 110 kmh/68 mph on Trans-Canada Hwy)
3/20/14 (Wyoming - interstates raised to 80)

5/29/14 (Maine - research indicates that last year's bill authorizing 75 mph on all freeways also authorized DOT to raise 4-lane divided highways to 60)
