A truck driver has died after suffering an apparent medical episode and crashing his vehicle on a busy link between Brisbane and the Gold Coast, causing hours of traffic delays. It happened just before 6am on Thursday on the M1 Pacific Motorway through Gaven, about 67km southeast of Brisbane. The truck had crashed into the median strip separating the north and southbound lanes of the motorway. Police closed one lane of the M1, causing traffic to bank up in both directions stretching from Carrara to Ormeau – a distance of about 30km. Helicopter vision from 7 News showed huge stretches of traffic stuck at a standstill as emergency crews worked to clear the crash site.
