How to judge a safe gap at an Irish roundabout

See how waiting for a vehicle to pass gives you time to check for a safe gap.

Pick your exit early. Look for signs and lane arrows as you approach. Obey any traffic lights. At a yield line, slow down so you can stop if necessary. Give way to traffic coming from your right and traffic already on the roundabout. RSA Rules of the Road, roundabout approach

Imagine a vehicle is about to cross the path you would take into the roundabout. Let it pass. Check again, and enter only when you can do so safely. Watch for cyclists and motorcyclists as well as cars. Before you leave, check that you can reach your exit without cutting across anyone who is continuing around.
