When
you
are
in
England,
you
must
be
very
careful
in
the
streets
because
the
traffic
drives
on
the
left.
Before
you
cross
a
street,
you
must
look
to
the
right
first
and
then
the
left.
If
the
traffic
lights
are
red,
the
traffic
must
stop.
Then
people
on
foot
can
cross
the
road
carefully.
If
the
traffic
lights
are
green,
the
traffic
can
go.
People
must
not
cross.
In
the
morning
and
in
the
evening
when
people
go
to
or
come
from
work,
the
streets
are
busy.
Traffic
is
the
most
dangerous
then.
When
you
go
by
bus
in
England,
you
have
to
be
carefully,
too.
In
many
English
cities,
there
are
big
buses
with
two
floors.
You
can
sit
on
the
second
floor.
It
is
very
interesting
to
see
the
city
from
there.
