I agree, that was my solution.

Easy...stick a set of traffic lights on the intersection so we have less deaths on the road.

Chrissyo (Chris) · #8 22-10-2005, 11:04 AM

I would agree with the turning left thing. I thought the apperance of a collision might just be an optical illusion, but I tried it out and doesn't work. See attchment.

ving (David) · #9 22-10-2005, 11:09 AM

well left turn it is then...

Silly me, I'm going for my L's next month so I should know this. Unless otherwise signed, you must give way to the right

ving (David) · #12 22-10-2005, 11:37 AM

given that tho chrissy, they'd all be giving way to eachother and no one would move

Chrissyo (Chris) · #13 22-10-2005, 11:49 AM

Hehe, darn

I had better go study that drivers ed book a bit more!

Are we talking about UK or OZ here. In UK they would wait until one drive dies of old age or they build a roundabout,
but here at least one would just floor it - "I told you I could make it"

Yeah I vote for left turning. However it does say they all go forward. I suppose the left turning is forward.

Hi Paul

I assumed that each driver is moving forward in the reference frame of their own motor vehicle, so even though they are "turning left", from their own perspective, they and the motor vehicle are still moving forward.

I shied away from using the intersection as the reference frame.

But then, I may be overcomplicating things......

Cheers

Yeah makes sense Denis.

Does anyone have the correct answer for this. Like to know whether we are correct or not.

ballaratdragons (Ken) · #18 22-10-2005, 04:02 PM

I can only assume they all turn left. It says "drive forward and continue their journey"
it does not say "drive straight ahead". Their journey, in that case, must have been around the corner ,and to acheive this they must use forward motion to make the car turn!

Yeah, I found it. I just went to google and typed in "Conundrum #11 Tricky Intersection" and about the second one was an ABC site with the same question (and answer).

The answer is...

SPOILER!!

All vehicles turn left.

Is above in white ^^^. Highlight it to see it.

ballaratdragons (Ken) · #20 22-10-2005, 05:42 PM

Hooray, we got it!!!!!!

We are just too good for words!!!

Highlight the line above! ^
