Opinion: 70 mph Speed Limit Should Apply to Metro Chicago
…And Residents Should Be Prepared To Go To Prison For 6 Months If The Speed Limit Doesn’t Go Up
The recently signed 70 mph speed-limit bill begins to undo the damage done by the national 55 mph limit established in 1973. Illinois had a 70 mph speed-limit 40 years ago and it was not just for rural interstates. Most state highways, even two-lane highways, had limits higher than the 55 mph still in place on metro Chicago’s interstates. In some states, unpaved roads carry the same 55 mph limit as the Tri-State Tollway.
After reading the recent Illinois speed-limit bill and discussing it with sponsor Jim Oberweis, it’s clear to me that the bill was intended to cover, and should apply to, metro Chicago for the same reasons that it makes sense downstate. The speed-limit for all metro Chicago interstates will revert to 70 mph unless the Illinois Department of Transportation produces an engineering study proving the new limit unsafe. County boards may also be able to block the new limit. IDOT could make the data say what they want it to say, but that would be a disservice to tollway customers and all area drivers.
If IDOT abides by the traffic engineering principles espoused by other transportation and police departments across the country and around the world, it is nearly certain that the findings would dictate a speed-limit of 70 mph (or higher) for metro Chicago expressways, with the possible
exception of those inside the city limits. Illinois would not exactly be a leader in making such a move. Already, 33 other states have speed limits of 65 or higher for URBAN areas. Many of these other states, like California and Texas contain major urban centers like Chicago. Even in nearby Michigan, a majority of Detroit area expressways are posted at 70 mph.
IDOT and the county boards should allow metro Chicago limits to revert to 70 mph. All the evidence indicates that there would be no negative impact on safety. In fact, the opposite is true. Overall metro Chicago highway safety would probably be improved. Here’s why:
1. Nearly 90% of fatalities occur on secondary roads. Only 11% of fatalities occur on Illinois interstates, including metro Chicago. So, those big fatality counting signs over the tollways are telling us about the risk after we exit.
2. Higher speed-limits on interstates help draw traffic away from highways which are more dangerous, thus increasing overall road safety. This is always a key point, but even more-so in metro Chicago since like Interstate 355 and Interstate 294 charge tolls. There is already a big incentive to take the more dangerous secondary highways such as old 53 and Route 59 for example.
3. For decades, traffic engineers have promoted establishment of speed-limits based on 85th percentile speeds – the maximum speed at which 85% of motorists travel when unencumbered by traffic or enforcement. Well informed state police and transportation departments around the world advocate this approach. The position taken by IDOT is inconsistent with its peers.
4. Speed-limits have very little impact on the pace of faster traffic drivers, including the police, ignore under (and over) posted limits.
5. When limits are under-posted there is one group of drivers who travel at careful and prudent speeds and another group which tries to adhere more closely to the law. Higher interstate speed-limits improve safety by reducing speed variance, road rage and weaving.
6. Under-posted speed-limits breed disrespect for all laws, especially traffic laws. This leads to speeding in construction zones and on secondary roads and other bad behavior. When IDOT has no credibility on speed-limits it reduces their credibility on warnings about texting, cell phone usage, etc.
7. Under-posted speed-limits leave drivers bored, unengaged and distracted. Since driving does not demand their full attention, drivers talk on the phone and even text while driving.because they can. Texting is probably not an issue on the autobahn.
8. Even with increased speed-limit, Illinois interstates and other highways are still posted at or below the limits which were in place in 1973 (pre-55). Since then, the handling capability and safety equipment on vehicles has improved dramatically such that limits of 80+ should be the norm for rural interstates as in many other parts of the industrialized world. An increase to 70 should not be cause for any concern.
9. Insurers and others who profit from speeding tickets tend to cite studies which count the raw number of fatalities (if they are going up) rather than looking at the rate per mile driven. The actual fatality rate has fallen steadily for decades during times of both rising and falling
speed-limits. As found in a recent study published in the Florida Public Health Review, the Insurance Institute for Highway Safety (IIHS) has a tendency to disregard data which does not support their preconceived conclusions.
10. Higher limits reduce congestion and may actually save fuel by allowing drivers to keep a steadier pace.
One final point makes this a rather urgent matter for Chicago area drivers. Beginning 1/1/14, unlucky drivers who “go with the flow” of average traffic speeds could end up paying a $1,500 fine and go to prison for 6 months. If nothing changes, that will be the penalty for going 81 mph in metro Chicago (26 over the 55 limit).
This Class B Misdemeanor penalty presumes that proper speed limits are in place and would not be so bad if the speed-limit was 70 mph. In that case, 96 mph could lead to jail time. With heavy-handed penalties like this, it is absolutely critical that Chicago area interstate speed-limits be set
properly. We all know the 55 limit is a bad joke and the notion of going to jail for 81 is asinine. It’s time we put an end to it.
Wheaton resident Steve Doner is a former Illinois Chapter Coordinator for the National Motorists Association. He currently commutes approximately 30,000 miles per year on Chicago area interstates. As an auditor and financial consultant he has driven nearly all area expressways during the past 30 years. Doner is the father of two teenage drivers and strongly believes that his children would be safer on the roads if speed limits were increased.
