Signs of driver fatigue are trouble focusing, daydreaming, yawning or rubbing your eyes repeatedly and drifting from your lane, tailgating and missing signs or exits.
The SH3 stop just south of Bulls is one of five at key major traffic points around the country.
Central District police want to remind motorists to always wear their seatbelts and drive to the conditions. Central District road policing manager, Inspector Dave White, said seatbelts were not accessories - they saved lives. "Before you start your journey make sure everyone in your vehicle, especially children, have their seatbelts on."
Mr White said there were added risks when driving on roads during peak holiday traffic and it was vital that motorists drove to the conditions and remained aware at all times.
"Our district has some of the most frequently used roads and highways in the North Island and during holiday season they can become congested and delays can be long. Making sure your vehicle is fit for the journey and listening to radio traffic updates before you embark could save you unwanted frustration in the long run."
During the official holiday period - from 4pm today until 6am Tuesday - the speed limit tolerance is 4km for all permanent posted speed limits.
