Posted limits vs. "basic speed" laws
Every state also has a basic speed rule: you must not drive faster than is safe for the conditions. In rain, snow or heavy traffic you can be ticketed even below the posted limit.
Trucks and towing
Some states set lower limits for trucks or vehicles towing trailers. California, for example, limits them to 55 mph on each road.
