The prosecution case against a truck driver charged with manslaughter is expected to start on Tuesday after legal argument delayed proceedings.

Christopher Paul Hennessy is accused of failing to properly secure his amusement ride load, which swung out and killed another motorist.

He was allegedly transporting the "Hurricane" back to its holding yard in May 2016 when a restraint failed and the stabilising arm hit a Commodore.

An 80-year-old motorist, Aldo Casasola, died.

Hennessy pleaded not guilty to manslaughter on the opening day of his Brisbane Supreme Court trial on Monday.

He also pleaded not guilty to an alternate charge of dangerous operation of a vehicle causing death.

Opening arguments are expected to start on Tuesday.
