One of the most important things to remember when entering a roundabout is to yield. This means only stopping to give right of way to vehicles already in the roundabout. If the way is clear, you don't need to yield. Traffic already in the roundabout always has the right of way.
Once you've picked your lane and signalled, you're ready to enter the roundabout. To safely enter the roundabout:
Once you are in the roundabout, simply stay in your lane until your exit. It is important to choose the correct lane on entry so you don't have to change lanes in the roundabout.
While driving in a roundabout, watch for large vehicles that may take up more than one lane. Never pass a large vehicle when there isn't enough room to do so. Give large vehicles extra room to ensure they are able to safely enter and exit the roundabout.
