C.27
MINIMUM FOLLOWING DISTANCE
Rear-end collisions account for nearly a third of all crashes. The main cause is
travelling too closely behind another vehicle and/or looking away for
just a second at the wrong moment.
This dangerous practice, commonly
called tailgating, is widespread.
Some drivers may not even realize that they are following too closely, never having
learned the two-second rule:
This well proven method of measuring
a safe minimum
distance works at any speed:
As the vehicle ahead of you passes a certain fixed object (tree,
road-sign
etc.) start counting slowly:
‘One thousand and one, one thousand and two’.
You
must be able to finish this (two seconds) count comfortably before passing the
object otherwise you are not driving at a safe distance!
|
How
to measure the >
two-second safety margin:
The driver in the white car starts
counting, as the van passes the road sign. If
the driver can
comfortably count-out two
seconds, before passing the sign, the
distance to the preceding vehicle is safe.
At 80 km/h or 100 km/h two seconds are obviously a far greater distance
than at 20km/h. However, the principle remains the same! |
 |
Allow a further second or two under the following circumstances:
| Travelling on a gravel road or wet
road surface.
|
Increased
braking distance! |
| When visibility is
reduced under adverse conditions. |
In
heavy
rain, fog, at night. |
| When being followed too closely.
|
Allow
extra space for the tailgater.
|
| Following
a learner driver or interstate visitor. |
That’s
what the L- plates are for. |
| Travelling at higher speeds
over a
long period
|
Allows
for slower reaction! |
A standard excuse for following too closely, is the concern that motorist in the
other lane fill up your two second safety gap. Let them! Simply,
drop back and establish the two seconds distance again.
 |
<
Driving
too closely behind a truck, bus or van, reduces your forward
visibility.
At
high speed this dangerous practice make your passengers and
the truck driver feel uneasy.
Motorists
who tailgate are less prepared for an emergency further down the road. They are
forced to constantly watch the vehicle ahead; not a relaxed way of driving! |
Motoring is both, more
enjoyable and safer, when staying
well back and scanning traffic for hazards ahead! Driving in that
manner avoids heavy braking. It reducing the chance of a rear-end
crash.
Stay
well back - you
will see more
of
the circus ahead !
