Point of no return
Prior to coming to work for Nathan’s Driving School, I
had driven a Semi Tractor and Trailer (a.k.a. Big Rig) for a few years; nationwide.
The experience was mostly good. The advantage was
that I did get to see a lot of the United States. One of the few dis-advantages was that I couldn’t stop long enough at some interesting places to
wander around a learn about the area and its history. Like many truckers, there are a lot of stories
I could tell you. One that comes to mind is the dear little old lady in
Miami.
I’m sure that a few of our classroom instructors are
using diagrams and describing to you about a point in the turn at an
intersection that they refer to as “a point of no return.” I haven’t heard the lecture, but I’ve seen the
drawing on the white boards in our classrooms at Nathan’s. I’m sure that
the instructors are informing our students that there is a point in a turn and
in your decision making that you are committed to complete the turning
procedure. At that point, you need to proceed intentionally and without
delay so that you are not barely moving onto the street that you have turned
onto. Another way to put it would be, once committed you need to keep moving and be assertive about the maneuver (notice I said assertive and not aggressive).
This is so you can get out of the way of oncoming traffic. It’s not good
to be hesitant during and after a turn.
Let me give you an example from my days as a truck driver.
Do you know how much a car can weigh generally? If you guessed between 1 to 2 tons, you’d be close to correct and in pounds that
about 2,500 to 3,500 pounds-ish. Let’s run with 2,000 pounds to make math easier for me (I am not a math person, but I get
by). So now that we have a general idea how much a car can weigh, do you know how much an 18 wheeler truck can weigh? A Semi tractor / trailer rig, and this
would be a “box” truck carrying dry goods, will weigh in at about 98,000 pounds
fully loaded. Wow! That would be about 40 cars worth of
weight. Okay let’s let that sink in a sec. You have most likely
been exposed to science and physics etc. That’s a lot of mass wouldn’t
you say?
How much distance does a car take to stop? You
probably heard this in class or will have. At 60 mph a typical car takes
about 239 feet – including reaction time. This is 1 to 2 tons of car.
How about that fully loaded 18 wheeler? About 512 feet. Doesn’t sound like much
difference unless you are at the scene.
I don’t want to blow things out of proportion here but
let’s say you were in my seat in the truck and going about 45 mph on a 4 lane busy highway in Miami, Florida. All lanes are
full and it’s a sunny dry day. I’m just going with the flow of traffic
for the most part as the speed limit was 45 mph but you know how that is, few follow it…
When all of a sudden a sweet little old lady in a mid-size sedan pulls
out in front of me about a half a block away from me. The truck is heavy
and loaded to the max.
OH CRAP I’m going to hit her for sure ☹ I slam on the air brakes and the trailer tires begin
to lock up and smoke. Meanwhile traffic in back of me and to the side of me panic and swerve to miss me because by now the trailer is
starting to move from side to side. I hit the air horn to encourage the
sweet little old lady to get out of the way. Because my friend, she is poking in the right lane and the left
lane is full of cars. Poking? Yep about 10 mph I would guess.
I hope y ou haven’t been in an auto accident and if you
haven’t, I hope you never experience one. I’ve been in two.
The thing I remember most of both is the noise. For
a few moments in time it is complete crazy and noise.
You can imagine how traffic around myself and the truck
reacted. Horns, skidding, dodging, tire smoke, more horns… in a
matter of seconds.
And the little old lady? All of this didn’t bother
her one bit. She just kept going straight on down the road at 10 mph as
if nothing was happening.
I did get slowed down enough to avoid hitting her and
anyone else. But the truck’s front end was about 3 inches from the rear of her
car. I must have used about 77 angels with me that day. I did have to pull over and stop for a minute
or two to recover. It scared me.
To this day I doubt that the sweet little old lady ever
knew. She was oblivious to it all. I would
guess because of the noise and action and her reaction, she couldn’t hear or see much. The moral of this story?
Had she just got up to speed during and after the turn there would have been no
issue. See you have to commit and move on down the road or you risk getting
creamed.
Well I guess the first moral is make sure no one is
coming before turning right and make sure it isn’t a giant truck. And had
I hit her, she may very well have died.
Learning to drive is tough for most. If not for
you, then be thankful and don’t get overly confident as there is more to it
than an over confident student realizes.
For those of you that find it scary at times and
troublesome. Welcome to the club, most of us went through what you are
going though. Learning to drive isn’t easy at times. But keep your
common sense about you and whatever you do don’t pull out in front of someone
and when you turn – keep moving and get up to flow with traffic or the speed
limit whichever is less.
Drive safe and try to enjoy driving – it is fun and gets easier with practice.
