Many drivers feel uncomfortable with certain roundabouts regarding them as high risk'.

The single most common mistake at a roundabout is only looking to your right as you approach, because that is where you expect traffic to come from.

But what about the car ahead of you can he see something that you can't?

It is better to gather as much information as you can start to check to your right, straight ahead, left, and all your mirrors.

By carrying out your observations in this sweeping/scanning motion, you are more likely to pick up if the car in front decides not to go for some reason.

The classic rear end shunt, caused by the driver ahead not going when you think he's going, can thus be avoided.

Drivers often approach the roundabout with the plan to continue unless they have to stop because of other traffic.

The problem here is you may notice another car just as you get close to the roundabout, but you are more likely to speed up, opting to 'take a chance' because it is difficult to change your mind at the last moment.

A slightly different, but very much more effective mental outlook is to approach the roundabout thinking 'plan to stop but look to go'. As you scan, remember you are looking for gaps, as well as vehicles.
