Across the United States, maximum speed limit laws vary dramatically. In the mid-1990s, many states increased speed limits to 75 mph on select roads. More recently, some states have established speed limits greater than 75 mph. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 328: Safety Effects of Raising Speed Limits to 75 mph and Higher is supplemental to NCHRP Research Report 1006: Guide to Understanding Effects of Raising Speed Limits.

Over the past decade, there has been a trend toward higher speed limits, especially on rural interstates and freeways. Eleven states have increased speed limits to 75 mph, with some of them raising the limit as high as 85 mph on freeways and 75 mph on other roads. The TRB National Cooperative Highway Research Program's NCHRP Research Report 1006: Guide to Understanding Effects of Raising Speed Limits provides a better understanding of the expected safety implications of increasing speed limits to 75 mph or higher. Supplemental to the report are a presentation and NCHRP Web-Only Document 328: Safety Effects of Raising Speed Limits to 75 mph and Higher.
