The map shows there is a difference of 25 mph between the state with the lowest speed limit (Hawaii) and the area with the highest, a toll road in Texas between Austin and San Antonio where drivers can legally travel at 85 mph.
It is important that businesses who run their own fleet of vehicles make sure every driver knows these interstate speed limits. It's easy to get caught out when there is so much variation.
You might want to consider installing a tracking device capable of reporting real-time driver speed information in each of the vehicles in your company's fleet, especially if your drivers regularly cross state boundaries.
