Investigations have been continuing into a crash which claimed the lives of a retired school rector and two teenage exchange students.
The section of A9 affected leads to the Kessock Bridge and Inverness
Donald MacLeod, 82, a former rector at Fortrose Academy on the Black Isle, died in Monday's smash on the A9.
Carlos De Guzman, 15, and Gianmarco Vilcapona, 14 - who were visiting from Lima in Peru - also died.
Police were trying to establish why Mr MacLeod's Honda CRV crashed into a lorry parked in a lay-by at Inverness.
The teenagers were members of an exchange trip from St Andrew's School in Lima which was organised by the Free Church of Scotland.
Mr MacLeod had been driving them to North Kessock where they were to meet up with the rest of their group for a day trip to Stornoway in the Western Isles.
The crash at 0755 BST involved a Tesco lorry and the Honda about 500 yards from the Kessock Bridge roundabout.
A section of the northbound A9 carriageway was closed for more than four hours, it later reopened at 1230 BST.
