Is Driving Faster, Safer?

JAMES JOYNER · SATURDAY, JULY 8, 2006 · 5 COMMENTS

Yesterday’s OpinionJournal notes something we don’t hear everyday: “Driving on the highways is safer today than ever before.”

In 2005, according to new data from the National Highway Safety Administration, the rate of injuries per mile traveled was lower than at any time since the Interstate Highway System was built 50 years ago. The fatality rate was the second lowest ever, just a tick higher than in 2004.
Both during the Bush administration, I’d point out. If post hoc ergo propter hoc works for the other side, it should work for us, too.

As a public policy matter, this steady decline is a vindication of the repeal of the 55 miles per hour federal speed limit law in 1995. That 1974 federal speed limit was arguably the most disobeyed and despised law since Prohibition. “Double nickel,” as it was often called, was first adopted to save gasoline during the Arab oil embargo, though later the justification became saving lives. But to Westerners with open spaces and low traffic density, the law became a symbol of the heavy hand of the federal nanny state. To top it off, Congress would deny states their own federal highway construction dollars if they failed to comply.

In repealing the law, the newly minted Republican majority in Congress declared that states were free to impose their own limits. Many states immediately took up this nod to federalism by raising their limits to 70 or 75 mph. Texas just raised its speed limit again on rural highways to 80.

This may seem non-controversial now, but at the time the debate was shrill and filled with predictions of doom. Ralph Nader claimed that “history will never forgive Congress for this assault on the sanctity of human life.” Judith Stone, president of the Advocates for Highway and Auto Safety, predicted to Katie Couric on NBC’s “Today Show” that there would be “6,400 added highway fatalities a year and millions of more injuries.” Federico Pena, the Clinton Administration’s Secretary of Transportation, declared: “Allowing speed limits to rise above 55 simply means that more Americans will die and be injured on our highways.”

Table Safe at Any Speed


We now have 10 years of evidence proving that the only “assault” was on the sanctity of the truth. The nearby table shows that the death, injury and crash rates have fallen sharply since 1995. Per mile traveled, there were about 5,000 fewer deaths and almost one million fewer injuries in 2005 than in the mid-1990s. This is all the more remarkable given that a dozen years ago Americans lacked today’s distraction of driving while also talking on their cell phones.

Indeed. Of course, bivariate analysis tends not to be particularly useful. More of us are driving larger vehicles than in 1995, most states require people to wear seatbelts, cars are equipped ith air bags, and so forth.

Of the 31 states that have raised their speed limits to more than 70 mph, 29 saw a decline in the death and injury rate and only two–the Dakotas–have seen fatalities increase. Two studies, by the National Motorists Association and by the Cato Institute, have compared crash data in states that raised their speed limits with those that didn’t and found no increase in deaths in the higher speed states.

This, however, would seem to help alleviate the defects just described. Now, there may be differences in SUV ownership rates and so forth in fast vice slow states that explain this. Still, it’s quite interesting that a comparison of contemporary data shows no difference in fatality rates. One would think these states would have roughly equivalent rates of SUV ownership, cell phone use, seat belt wearing, and the like. Indeed, if anything, one would think “faster” states are predominately rural and thus poorer and more likely to be driving older, less safety featured, cars and less likely to be wearing seat belts.

Jim Baxter, president of the National Motorists Association, says that by the early 1990s “compliance with the 55 mph law was only about 5%–in other words, about 95% of drivers were exceeding the speed limit.” Now motorists can coast at these faster speeds without being on the constant lookout for radar guns, speed traps and state troopers. Americans have also arrived at their destinations sooner, worth an estimated $30 billion a year in time saved, according to the Cato study.

Or, it could be that people are pretty much driving as fast as they safely can everywhere and the posted speed limit is simply irrelevant. In my experience, people on the highway don’t drive the speed limit or the speed limit plus 5 or 10 mph; they drive around 75 mph regardless. My guess is that people in Texas are driving 80-85 mph in the 80 mph limit zones and 80-85 mph in the 65 mph zones.

Wetende dat USA de oliecrisis-55 mph op hun snelwegen hanteerde - #officieel tot 1995- waar amper 5 % zich aan hield... (menige staat veranderde vanaf 1988# die 55 mph-NMSL), tja US-staten waar men nu tot 129-137 kmh offic. mag rijden zijn geen uitzondering.

Setting Speed Limits: Yesterday, Today and Tomorrow

uit Wiki: 113 kmh limiet Texas: (105 kmh ´s nachts)

http://en.wikipedia.org/wiki/Speed_l..._United_States

Vergelijk Limburg, baan naar niemandsland, niet 70 mph maar 70 kmh in 2013 (van algemene 90 kmh, zie venster linksboven in link **cursor verschuiven):
** https://www.google.be/maps/@51.03784...y5fg!2e0?hl=nl

**vóór 2013 nog 90 kmh, nu 70 kmh !


arbitraire vbn USA uit wiki:

Even in-state examples point to arbitrariness. For example, I-10 and I-20 in far west Texas have had the following speed limits despite no significant changes in roadway characteristics:
Before 1963: 60 mph day/55 mph night
1963–1974: 70 mph day/65 mph night
1974–1986: 55 mph
1986–1995: 65 mph
1995–2001: 70 mph day/65 mph night
2001–2006: 75 mph day/65 mph night
2006–2012: 80 mph day/65 mph night
2012–: 80 mph

Of een ~ 45 % verhoging van de snelheidslimiet op 2 Interstates.
