Two scenarios for what happened in the moments before a Danish cyclist's death on a notorious stretch of road in Brisbane have been outlined at a coroner's inquest.

Rebekka Meyer, 22, was hit by a truck on Annerley Road in South Brisbane last September.

Senior Constable David Armitage from the Forensic Crash Unit, who inspected the site, told the inquest the point of impact was clear but the cause of the accident was not.

"There were ... two things that could have caused the accident, but I couldn't say definitively," he said.

"The initial possibility was the bike was at the stop line already and the heavy vehicle approached, but the driver didn't see her.

"The second is that Ms Meyer placed herself if front of the heavy vehicle while it was stationary."

Theinquest is examining Ms Meyer's death and whether the Stanley Street and Annerley Road intersection needs upgrading to prevent similar accidents.

Just 13 months before Ms Meyer's death, Brisbane rider Leslie Karayan died on the same road - which has seen 34 crashes involving cyclists between 2007 and 2011.

The driver of the truck, meanwhile, told the inquest he did not see or hear anything unusual before the crash.

Jody Jeffery told the inquest that as he pulled through the intersection at Annerley Road, it felt like the back left drive wheels of his truck hit
