Summer travel safety message repeated
Road safety messages to drivers to not take risks during the summer holiday period are being repeated by a host of organisations, with reminders to drive to the conditions.
Among them, freight sector group Transporting New Zealand, which said drivers should expect delays, as there are lots of road works this summer, and trucks remain on the roads delivering essential supplies.
Its chief executive Dom Kalasih said holidaymakers need to be vigilant, and always drive safely.
"Our drivers, unfortunately, they do see some crazy stuff out there - especially dangerous driving. And that can be them being passed when there's not really enough room, or cars oncoming completing passing manoeuvres", he said.
"Many crashes happen where speed, seat belts, distractions and impaired driving - whether that be by fatigue, alcohol or drugs - are contributing factors, and all those things can be managed.
"So we're asking everyone out there to try really hard in those areas."
