A FEW millimetres of rain has been enough to cause traffic chaos with crashes on several major roads leading into Brisbane this morning.

In the latest incident, several vehicles have collided on Sandgate Rd, at Roscommon Road blocking the left lane inbound, causing delays.

 Earlier, a car and a truck came together on Gympie Road at Kedron, blocking the southbound lanes near Lassiter Road.

The crash has been cleared and traffic is moving again.
