    Editor’s Note:  This is the first in a series about  Electronic Stability Control
by Glen Nicholson

When you heard the shocking news that five people died on Hwy 16 at Cluculz Lake, did you blame someone?  Did you nod in agreement when authorities implied that the vehicle was driving at speeds inappropriate for road conditions?  Did that solve the problem?  I think not.

Dr. Claes Tingvall, Director of Traffic Safety for the Swedish National Road Administration talks about blaming the driver for problems caused by factors beyond their control:  “The road transport system and its stakeholders have been given the task of providing the citizen with mobility but have at the same time unintentionally generated one of the largest health catastrophes ever seen in the history of mankind.  In a moral and legal sense, there has always been a citizen to blame.”

To err is human, especially for drivers confronted with a confusing constellation of challenges: a busy highway, a carload of passengers, a deadline, a blizzard, and marginal traction.  Blaming the driver gets us nowhere.  Nor is it useful to blame the weather.  We live in British Columbia.  It’s winter. 

Rather than blaming problems beyond our control, why not focus on a cheap and easy solution.  We can improve control of our vehicles through a simple technology called Electronic Stability Control (“ESC”).  ESC detects and prevents skidding by applying one brake to one wheel and/or reducing engine power.

ESC works fast; much faster than I can.  ESC reacts in 1/25th of a second, and often corrects skids before I realize I have lost control.  To do what ESC does, I would need four feet, four brake pedals, and superhuman reactions.

ESC is profoundly effective.  Experts around the world say ESC is the most important safety innovation since the seatbelt.  The Insurance Institute of Highway Safety says that ESC reduces fatal crashes by 43 percent, fatal single-vehicle crashes by 56 percent, and fatal single-vehicle rollovers by as much as 80 percent.

Seatbelts, airbags, head restraints, bumpers, roll cages, and other passive safety devices have one unfortunate thing in common.  They don’t work until the crash.  ESC is an active safety device that intervenes before the crash.  And ESC is most effective in reducing serious loss-of-control crashes; the ones that main or kill. 

The best kind of crash is one that never happens.  However, if a crash becomes inevitable, ESC makes crashing safer by keeping the vehicle pointing where the driver is steering.  Rollovers cause almost one-third of fatalities.  ESC keeps the vehicle travelling forward, making it much less likely to trip sideways and roll over.  And it is safer to hit a solid object frontally than sideways because cars have more frontal than lateral crash protection devices.

ESC protects occupants of the vehicle.  ESC also protects other road users (without ESC) because the ESC vehicle is less likely to lose control and hit them. 

Dr. Tingvall once said, “Cars without ESC ... should be phased out as soon as cars with ESC are available.”  ESC was first installed in production vehicles in 1995 and is now available from all auto makers.  And ESC is cheap.  It costs manufacturers only $111 to add ESC to a vehicle.  As a new-car option, ESC retails for as little as $450. 

Unfortunately, some manufacturers have restricted ESC to expensive models, forcing buyers to buy luxury features they don’t need in order to get a safe vehicle.  ESC costs less than seat belts.  It would be unthinkable if seat belts were only available in expensive cars.  Why is ESC not in every new vehicle?

Glen Nicholson is an independent safety advocate , this is the first of several articles about ESC.  For more information, look up “Electronic Stability Control” on Wikipedia at this link:

I have it in my truck and it does work very well. You notice it on hills when it robs power to keep the tires from spinning, or if you kick it out a bit on a corner it stabalizes almost as soon as you take your foot off the gas. If its only a few bucks maybe it is something that should be legislated.
I actually turn mine off (in town) when it's slippery, it's just too intrusive & annoying. I do use it on the highway.
What do you find annoying? Is it the ESC light that flashes when you skid?

Some times a little tire slip is useful when turning for instance. I'm not talking about anti-lock brakes, I'm talking about acceleration. I don't neccesarily want the 'nanny' cuting power at the slightest loss of traction.
ESC is what is needed in front wheel drive and AWD vehicles. The family was in a front wheel drive car and most likely when she started to skid she probably took her foot off the gas. That is a no no in front wheel drive vehicles because of the drag to the front wheels from the engine that is no longer under power. When that happens the back end will come around right now. That is also why you don't put snow tires only on the front. The trick is to feather the throttle, takes practise.

This makes me wonder about the frequency of spin related accidents since front wheel drive became the predominate vehicle on the roads.

Maybe a little less reliance on electronics and more on common sense would make the roads a lot safer?
Doesn't common sense include buying the right safety equipment?

The thing with common sense is that it isn't all that common!
Safety equiptment is wonderful. The right kind is even better. And when used in conjunction with common sense it is fantastic....
But the safety equiptment should not be used to try and protect us from overdriving our abilities and in some cases I really think that is what happens



I agree with BCRacer.

A safety expert should know that the way people use equipment is not static. There is a tendency that when one uses technology to improve safety, people will begin to feel more confident and raise their level of expectation. They will rely more on technology working than on their own intuitive approach.

While snow may not be under people's control, the choice to drive while it is snowing and the roads are icy is. In this case, the risk of missing a medical appointment (I believe that was the reason for the trip) and dying was less than the risk of travelling in the snow and known icy road conditions and dying.

Not only that, but the whole family went. I am assuming that the children could have stayed behind with a friend or relative. The warnings were on the radio constantly about not driving unless you had to.

It appears to me that the way this accident happened and the fact that the other vehicle was a truck while the passenger vehicle was about as small as they come, ESC would not have helped.
An official blamed the Cluculz crash on the driver for pulling out to pass and losing control. Some people would say the driver did not use common sense. Did she and four children deserve a death sentence for her error in judgement? I say she should be forgiven, and that ESC would have afforded her a chance to live and learn.
BCRacer suggests that some drivers overdrive safety equipment. This will be the discussed in next week's article.
From the linked site:

"As is the case with many safety features, they can lead to a false sense of safety among some drivers. This technology does not and cannot change the laws of physics.

Even if your vehicle is equipped with ESC, you must continue to drive prudently. If you drive too fast for the specific set of road conditions, you can still lose control even with ESC.

Good tire and brake maintenance are equally important for safety. The best ESC system can do little to assist you if your tires are worn-out, under-inflated or overloaded."

"ESC could have prevented approximately 30% of the crashes that involved loss of control"

I am wondering what accidents do not involve loss of control, other than those that were intentional.
ESC does not prevent T-bone or tailgating crashes unless the driver swerves to avoid the crash. ESC detects yaw (turning left or right) and intervenes when you are not turning where you are steering (loss of steering control).
Owl is right about good tires. ESC does not increase grip. ESC helps drivers take advantage of the available traction by reacting faster than humans can. Proper winter tires combined with ESC make driving much safer on our current slippery roads.
