Can you settle an argument in our house, please? Is it OK to change lanes while you’re going round a roundabout?


Auntie’s answer: The answer is a definite no. Once you are in the roundabout, you should stay in your lane until exiting. However, based on what I have seen from drivers in Cayman, there seems to be quite a lot of confusion about which lane you should be in from the start.

The rules of the roundabout are straightforward, so I am not sure why many drivers seem unable to transfer those rules to actual road conditions. Allow me to try to explain, in as simple terms as I can, the proper way to navigate through a roundabout.

I think the most important rule is that you always give way to the right when attempting to enter a roundabout. Too often it seems people are confused by this rule, especially on single-lane roundabouts which they seem to treat like a four-way stop, waiting for their supposed turn instead of entering when it is clear to their right. Or, even more dangerous is when drivers don’t wait and just roar into the roundabout, then speed up to avoid other cars. I have seen too many near misses for one lifetime. And don’t even get me started on all those drivers who seem to think it is not necessary to use their indicators, apparently believing the rest of the world will understand their intentions.

For a two-lane roundabout, which give people the most problems, before entering you should have already chosen either the right (inner) or left (outer) lane, depending on where you will exit. If you are taking the first exit, stay in the left lane, indicate left and continue merrily on your way. If going straight through, you can be in either lane but you need to indicate left after you pass the exit before the one you want. If going right, start from the inner lane, indicate right and continue in that lane; again indicate left before your reach your exit. That is basically it.

Single-lane roundabouts operate on the same principles but practically speaking should be much easier to deal with.

In case you need a visual aid, here is a link to every possible roundabout scenario and how to negotiate them. Hope it helps anyone still going around in circles when it comes to understanding roundabouts.
