Speed limits across the nation have been on the rise over the past two decades since Congress repealed the National Maximum Speed Limit (NMSL) law in 1995. Some have argued that these speed limit increases are simply aligning the law with reality, given that many motorists are regularly driving at speeds that exceed 55 miles per hour (mph) – the limit set by the NMSL.
A new study, however, has revealed that these speed limit increases are coming with a big cost – namely, the cost of thousands of lives.
In fact, as the Insurance Institute for Highway Safety (IIHS) has reported, the speed limit hikes that have occurred across the U.S. over the past two decades have contributed to at least 33,000 traffic-related deaths. This high fatality rate has “been so great that it has now largely offset the beneficial effects of some other traffic safety strategies1,” IIHS has pointed out.
Details & Findings of the IIHS Speed Limit Study
To evaluate the impacts of speed limit increases across the nation, IIHS researchers analyzed traffic fatality data versus speed limit increases for 41 states (leaving out 9 states and the District of Columbia due to their low rates of vehicle miles traveled).
In examining this data, researchers focused on fatality rates per billion miles driven (per state), taking note of what type of roads these deaths were occurring on (i.e., rural versus urban interstates). They also reportedly accounted for other factors that may contribute to roadway fatalities, like drunk driving.
What they discovered from their analyses was that:
- When speed limits go up, drivers will go even faster than the new speed limit, increasing the risk of auto accidents.
- For every 5 mph that speed limits increased, there was generally a 4-percent increase in the death rate (for a given roadway).
- Freeways and interstates, which were associated with the highest increases in speed limits, saw a roughly 8-percent spike in fatal crashes over study period.
- In 2013 alone (the last year of the 20-year study period), speed limit increases contributed to at least 1,900 deaths.
- These fatality estimates are likely conservative, as a number of states have continued to elevate their speed limits since 2013 (with at least five states in the U.S. now having speed limits set as high as 80 mph).
Commenting on this study and its findings, lead study author and IIHS vice president of research and statistics, Charles Farmer, has explained that:
Since 2013, speeds have only become more extreme, and the trend shows no sign of abating… We hope state lawmakers will keep in mind the deadly consequences of higher speeds when they consider raising limits.
