Every time I enter the roundabout in Pemberton, I cross my fingers hoping I'm going to make it out the other side. It is really amazing how many people don't seem to know the "rules of the road" regarding the use of roundabouts. A quick Google search will direct you to the Transport Canada website where the rules are plainly laid out. It's not that difficult people.
The most basic rule is that if you are entering a roundabout, yield to a vehicle already going through it. I don't know how many times I have almost been T-boned by people who either aren't looking, or just don't care. Another common mistake I see is people signaling to the left as they travel through the roundabout. This isn't necessary, as you need only to signal to the right before you exit the roundabout. If someone is travelling through the roundabout, and not signaling, assume they are staying in the roundabout. Roundabouts shouldn't be as difficult as we've made them to be.
