1999, tumbled 45 percent. The proportion surpassing 80 mph plummeted 85 percent. Large trucks slowed, too." (She did not mention that the IIHS survey of traffic speeds on Interstate highways in 2006 she referred to, found Montana, as compared with New Mexico and Nevada, had the highest compliance with the 75 mph speed limit on rural interstates: 76 percent.) Hawaii was the last state to raise its speed limit when, in response to public outcry after an experiment with traffic enforcement cameras in 2002, it raised the maximum speed limit on parts of Interstates H-1 and H-3 to 60 mph (100 km/h). Despite the repeal of federal speed limit controls, the 2011 maximum speed limits were on average lower than those of 1974: States with same speed limit as pre-1974: 25 States with higher speed limit than pre-1974: 8 States with lower speed limits than pre-1974: 17 The introduction to 70 or 75 mph speed limits was in effect that year. The introduction to 80 mph limits was in about 2005, and Texas introduced 85 mph in 2011. Although traffic deaths and death rates generally declined in the United States between 1989 and 2009, highway safety advocates have long continued to assert that increases in state speed limits after the repeal of the National Maximum Speed Law have had a detrimental effect on highway safety, and they have conducted many studies including statistical analyses that claim to support this argument. For example, the Insurance Institute for Highway Safety declared that "each 5 mph increase in the maximum speed limit resulted in a 4 percent increase in fatalities. The increase on Interstates and freeways... was 8 percent. Comparing the annual number of fatalities in the 41 states [studied] with the number that would have been expected if each state's maximum speed limit had remained unchanged since 1993, [we] arrived at the estimate of 33,000 additional fatalities over the 20-year period [from 1993 to 2013]." Speedometers Effective September 1, 1979, in a FMVSS that also regulated speedometer and odometer accuracy, the National Highway Traffic Safety Administration (NHTSA) required speedometers to have special emphasis on the number 55 and a maximum speed of 85 mph (140 km/h). Some manufacturers circumvented the rule by including extra lines beyond 85 to show higher speeds. However, on March 25, 1982, NHTSA revoked that Standard (FMVSS 127) entirely, eliminating speedometer and odometer rules because they were "unlikely
