Company Road Test Coming Up (Need Some Tips!)

It has been about a month since I passed my CDL Road Test and I have a company road test coming up with a 53FT Dry Van and I believe a Day Cab (could possibly be a Sleeper Cab, but don't think so).

Would appreciate help with a few questions:

1) In driving school we drove a Sleeper Cab with a 45Ft Dry Van and for the road test a Day Cab with a 40FT trailer.
How much addtional lag time should one give before starting your turn if you were in a Day Cab (or Sleeper Cab) and a 53FT trailer compared to what I have driven before?

2) When turning right from multiple turning lanes, which is the correct lane? Outside or inside lane?
I was watching the below two videos and the first one suggests at 0:55 to make your right turn from the outside lane.
However, the second video suggests at the 2:28 that you should make the right turn from the inside lane.

Which is correct for the most part?

3) Just to refresh my memory:
Turning Left: Go straight out into the intersection until whatever separates the two lanes of travel meets up with the middle of your driver side window before starting your turn?
Turning Right: Go straight out into the intersection until the passenger side window meets the fog line (solid white line) and for tight turns the double yellow line that separates the two lanes of travel meets the passenger side window before starting your turn?

4) This really did not happen during Driving School or on the Road Test, but when making a right turn, what if you meet a car that is too far up and is blocking you from completing the turn without hitting them? From what I understand you should just stop the in the middle of the intersection and wait for them to move out of your way?

Thanks

 

I am almost sure it will be a Day Cab as it is a home daily and local job.
(tossed in that it might be a Sleeper Cab because they do have a few of those too)

 

Your way of turning sounds just like this other video I was watching:

Only thing in that video he goes WAY over the double yellow line.
What if cars were there or if that was a intersection and cars are waiting at their red light?

 

I guess I get a little worried thinking about what to do if there is traffic blocking you from completing the turn.
Watching it again it seems you could also say he waited until his the passenger side mirror met up the double yellow line before starting his turn.
So using that as a guide might also work in some cases.

1) That's a good idea. See if I can get a feel of it before staring the road test

2) I got the left turn lane down (always outside). I think the one video suggested using the inside right turn lane because if you used the outside right turn lane the trailer may off-track into the inside right lane during your turn.

3) That was just a basic guide for when to start making turns my driving school gave us. Guess it might not apply everywhere.

4) This situation is my biggest fear. Traffic blocking your from making a wide right turn to complete it safely.
