One thing is clear from dash-cam video provided by survey respondents — WA motorists don’t know how to drive at roundabouts. Or perhaps they’re just confused?

The vision, which also included cyclists, shows motorists cutting in front of other vehicles on multi-lane roundabouts and failing to give way to cars already on the roundabout.

In one remarkable piece of vision, the driver of a four-wheel-drive vehicle leaves a roundabout at the wrong exit and heads in the wrong direction towards oncoming traffic.

Acting Road Safety Commissioner Teresa Williams said the commission had information available online to help educate drivers about the correct use of roundabouts, including an instructional video.

“This is one of the most visited pages on our website and I encourage any drivers who may be confused or not sure about the rules regarding roundabouts to have a look,” she said.

Ms Williams said that roundabouts were considered to be the safest type of intersection, because vehicles slowed down to drive around a roundabout and traffic was moving in the same direction reducing severe angles that can result in low-severity crashes.

Penalties for failing to give way at a roundabout are three demerit points and a $150 fine.

For all other offences related to not using a roundabout correctly, the penalty is two demerit points and $100 fine.

In a big change of policy to reduce congestion two years ago, Main Roads cut back on installing traffic lights, preferring instead to build roundabouts at busy intersections.
