It's an issue that affects drivers everywhere, not just Leeton or the wider Riverina area.

With this in mind, the NSW Centre for Road Safety is hoping to debunk the myths and confusion surrounding roundabouts.

The centre's Bernard Carlon said the circular intersections were actually one of the top 10 misunderstood road rules in the state.

"It really is pretty simple," he said.

"If you're approaching a roundabout, you need to indicate left if you are turning left, right if you are turning right, or not indicate if going straight ahead."

While simple enough so far, the next step is where many drivers disagree. Do you give way to the right, or is it a matter or first in, first served?

"You need to give way to vehicles currently in the roundabout," Mr Carlon said.

"That means do not enter into the pathway of another vehicle if it is in a proximity which will cause a crash.

"If you're in a large roundabout where a vehicle is already in but a significant distance away, you are still allowed to enter, but only if it won't cause contact with the other vehicle."

Once in the roundabout, drivers needed to start thinking about indication again, according to Mr Carlon.

"Again, if you are turning left, you continue to indicate the whole way until you have exited the roundabout," he said.

"If you are going straight ahead, you must indicate left as you get to the exit to show other drivers you are exiting the roundabout.

"When turning right, indicate the whole way around until you near the exit, where you then need to indicate left to show other drivers you are exiting and not continuing on, given that u-turns are legally allowed at a roundabout."

Multi-lane roundabouts cause a whole new level of confusion among drivers.

Mr Carlon said the key to getting through safely was a mix of common sense and caution.

"The usual road rules apply, you follow the direction of the arrows marked on the road," he said.

"If you change lanes in a roundabout, you need to indicate and give way to others already in the roundabout.

"For those waiting to enter, it is important to pay extra attention to those who may be changing lanes before you enter."

At the end of the day, Mr Carlon said roundabouts served to increase the safety of drivers at an intersection.
