How to Deal with Dual Carriageways | DTC-UK | Driving Test UK

Hello there, my name is Shaq. Today I’m
gonna be talking about dual carriageways. The first question is what is a dual
carriageway? Basically, it is a road generally with two or more lanes,
separated with a central reservation or a barrier of some sort. So on one side of
the barrier you get traffic going in one direction and on the other side of the
barrier you get traffic going in the opposite direction. Anyway regardless of
the number of lanes it will remain a single carriageway, unless there is a
barrier or a central reservation in the middle. The national speed limit for a
dual carriageway is 70 miles per hour. Many learner drivers dread the dual
carriageways due to their high speeds. In fact the dual carriageways are far safer
than normal residential roads. Most dual carriageways are joined via a roundabout
or a road leading onto them. When you join a dual carriageway by a slip road,
make sure you increase speed and match the speed of the vehicles on the
carriageway. If you are, let’s say try to merge onto the carriageway at 35
miles per hour when other traffic was doing 70 that
will be highly dangerous. Also just before you merge onto the carriageway
try to look over your shoulder slightly, move your chin to your shoulder just
like so. Even though you can see that your right-hand lane is clear,
somebody in the far right-hand lane may try to move left into that lane that you
want to move right. So that shoulder check is very important. Once you are on
the carriageway, try to keep the left-hand
lane. Unless you want to turn right or you’re overtaking. If you have to
overtake somebody that’s fine but you must move back in at the first safe
opportunity. Driving examiner’s do expect you to make progress so do try to keep
up with the flow of traffic. If it’s a 70 miles an hour dual carriageway, you’re
expected to do get up to at least 50 /55 miles per hour in the driving test.
However please bear in mind the two-second rule. You must leave at least
a two-second gap from you and the driver in front. Now when you exit the dual
carriageway, look out for the count down markers. 300 yards from the exit. 200
yards from the exit. 100 yards from the exit. Just some information for the
younger generation there is not much difference between yards and meters. Now
once you leave the dual carriageway make more use of the speedometer than you
would normally do. Otherwise you could find yourself driving a lot faster than
you think. I hope you found this video informative

  1. Hi Shack (hope I have spelt your name correctly). Your definition of a dual carriageway is actually incorrect. It is a road separated by a physical barrier which could be just a strip of grass. It does not have to have 2 lanes either side. It can be just one lane one side and one lane the other with a physical separation. I know you said generally 2 lanes, but this could still cause confusion and giving the correct description of what a dual carriageway is would be better. However nice video.

  2. I passed recently and unsure about signalling to come off a dual carriageway with 3 lanes where the left most lane is for going off the carriageway and the other two carry on past the exit slip road. In this case do you give a signal to confirm you are coming off to others or give no signal as it could be misleading as the exit slip road splits into two lanes. This is on the A1 southbound at Teams Valley near Lady Park Gateshead if you want to have a look on Google Maps. Thanks for the great videos I find them informative especially on areas I am a little unsure about πŸ™‚

  3. Failed my test because there was a cyclist on the left hand side of the dual carriage way.. I was driving around 45 mph as seen him from far but wasn't yet able to move over the right as was a busy lane. The examiner asked me to go faster as it's national speed limit. I panicked as the reason I wasn't doing 60 is cause I would reach the cyclist really quick as he was riding his bike so slow. When I decided to overtake the car coming on the right lane seemed to be very far from my mirrors but reached behind me so quick! Which means it was closer than it seemed! A big mess πŸ€¦πŸ½β€β™€οΈ all this happened 10 minutes from the end of my test which I would have passed if it wasn't for this big mess

  4. Good video… thanks
    But can you please make more video about dual carriageway please…. I find it extremely difficult

  5. Hi, I wonder when charging lane on dual carriage way do I need to check my blind spot? I feel hard to do that when speed is above 50 miles/hr, like 60 or 70 miles /hr. Thanks! (Would be nice if you could make a video ASAP talking about all situations that need blind spots checking)

  6. I'm looking for a video about where to wait when making a u turn in between a central reservation. Naturally you'd want to wait on the right side, because that's closest to us, but since we drive on the left in this country we'd wait on the left. I'm confused, please help
