In this driving lesson video
I'm going to go through some of the important theory questions
you should know before your driving test
but it's important to know the answers to these questions anyway
regardless of whether you have a test coming up or not
The first question - when are you allowed to overtake
on the left?
you can overtake on the left if the car in front
is turning right,
and you intend to turn left or go straight up ahead
so if the blue car here was
intending on turning right like that
the red car could overtake the blue car
on the left if he intends to turn left
or if he intends on going straight up ahead
so that's an example where you could overtake on the left
but only if it is safe to do so, you have to
pay close attention to signs and markings
in the locality that you are doing it as well.
And also in multi-lane traffic when the
traffic in the right lane is moving slower
than traffic in the left lane, in that case you could
overtake on the left also.
Next question then,
what does a red warning triangle on the road mean?
if you see a red warning triangle just like this
it means that there's going to be a hazard or a breakdown
about 50 - 75 metres
up ahead
so be careful, check your mirrors and indicate if needed
and be alert for any accidents or breakdowns
on the road
If you see a white triangle on the road
just like this here in the photograph
this means you have to yield (give way)
so on a roundabout or mini-roundabout you have to yield
to any traffic on the right or traffic already
on the roundabout
but if you see the white triangle at junctions
like crossroads or t-junctions
it means you have to yield to traffic on the main road
up ahead not just the right
The next question then, name some people in authority who you have
to stop for if they request you to do so
so you would have to stop for a Garda/Policeman
a school warden, that would be like the lollipop
man or woman outside schools so that children
can cross safely
anybody in charge of animals too, like farmers
moving animals across the road, you must stop
and obey their directions as they are in charge
of that situation
you must also stop and obey flagmen
in the case of roadworks, so keep an eye out for
roadwork signs just like these
and this sign here is the sign for a flagman up ahead
Another question then that's important to know the answer to
is what does the flashing amber arrow light mean?
if you see this particular light flashing amber
but pointing in a certain direction
that means you can go in that direction
but only provided there's no traffic on the right
or on the adjoining road up ahead
Another question then,
what is the difference between the single and double continuous yellow lines?
so this is to do with parking
if you see a double yellow line
just like this here
that means there's no parking at any time
and if you see a continuous yellow line
just like this
that means there's no parking during certain times
so for example no parking during business hours
or no parking during the times
that are stated on the sign that should be nearby
Next question is also very important
what is the minimum tyre thread depth on a car?
the minimum tyre thread depth is 1.6mm
now this is just the bare minimum
you really shouldn't allow your tyre thread depth
to get below about 3mm
you can judge the depth of the tyres by
putting you hand
along the central three quarters
as you can see here.
and the thread depth must
be measured in between the black and white lines here
and it must not be any less than 1.6mm
your tyre has to have depth for better grip on the road
especially in wet weather
And finally, how would you know if there was a turnoff
left or right, at night-time?
you would know there was a turnoff at night
because of these green indicator posts here
these will reflect and highlight against
your headlights thereby helping you to identify
the fact that there's a turnoff coming up
sometimes they are also accompanied by green
reflective studs on the road
otherwise known as cats eyes
so if you see the green cats eyes and these indicator posts
that means you're coming up to a left or right turn
and it should be easier to identify
So that's all for now

and I will see you soon.
