KEYWORD: ROAD TRAIN
A tractor-trailer consists of a truck in the front and a trailer in the back. In the vast
open territory of Australia, combinations like this are sometimes used with more than one trailer. They are known
as
road trains, since they can be really long — up to 50 meters! They supply areas that are not connected to the
rail network.
Parking the tractor
trailer in Reverse
YOU WILL NEED
› The assembled tractor-trailer truck
› IR remote control
› 5 AA batteries or 5 AA rechargeable batteries
› “ Boundary markers” such as extra pieces from the
experiment kit or boxes (see page 127)
HERE’S HOW
1. First, take a few dry runs. Which touch pad buttons
control which motor? And above all: Learn how to
drive the tractor-trailer in reverse.
2. Take a few “boundary markers” such as assembly
pieces or boxes, and use them to make a parking
space in which you can park by driving straight
backwards.
3. Now position the tractor trailer just in front of the
parking space and try backing into the space. Try
starting from different positions.
4. Make another parking space in which you can park
parallel to the driving direction.
5. Now drive your tractor-trailer alongside the parking
space and try to reverse into it.
DID YOU KNOW?
There are also other kinds
of vehicles whose great
weight slows down their
reaction time. Large ships
are an example. The captains of these ships have to
have a lot of training to be able to estimate how and
when the ship will respond to steering or stopping
commands. The Titanic, for example, had a stopping
distance of almost a kilometer!

WHAT’S HAPPENING
If you want the trailer to move to the right as you
back up, you have to drive the truck in the opposite
direction, to the left. It’s also important to turn
carefully and not too sharply, and to drive slowly.
That way, you’ll have time to see how the trailer
is responding and make adjustments.
