Traffic hotspots are on State Highway 4, 30km north of Taumarunui, known as "The Hiwis" and State Highway 41 near the summit, half-way between Taumarunui and Turangi.
Around National Park the main issue is driver behaviour, with motorists not ensuring the road is clear before entering intersections and doing u-turns in the National Park area. Ice on State Highway 47 is also a concern.
Ice on the roads is a problem for motorists in the Ohakune/Horopito area.
