"Why the rush?", police ask of speedster
A driver was caught travelling close to double the speed limit on a wet and stormy Waikato road yesterday, just as the Easter holiday period began.
Travelling 82km/h in a 50km/h speed zone, the motorist was zapped by the Waikato Roading Police Team yesterday afternoon.
A photo on the police unit's Facebook page, that earlier this year caught a motorcyclist travelling 169km/h, showed the speed radar's reading.
It also showed the wet and stormy conditions outside, which have sparked widespread travel warnings as motorists head away for the long weekend.
"This just happened in a 50km zone on a very wet and busy road near Paeroa," said the Facebook post.
"Seriously? Why the rush, and why the risks? No excuses!
"It's wet and our roads are getting busy, and it's gonna get even busier! Time to exercise some patience and start driving to the conditions."
The police also used the Facebook post to urge passengers to take responsibility for driving behaviour.
"If you're a passenger and your driver is taking risks speak up."
Easter road toll
The official Easter road toll period started at 4pm yesterday and continues until 6am on Tuesday.
Last year there was one fatal crash and 101 injury crashes that left 29 people seriously injured during the holiday period. Nearly all of those crashes occurred on the open road and 40 per cent were the result of a driver losing control or running off the road.
The NZTA's road safety director Ernst Zollner said yesterday that 279,000 more vehicles on the country's roads compared with a year ago increased the potential risks for drivers.
"We all need to approach the long weekend with a 'safety first' mindset to minimise the chances of making mistakes that can cost lives and cause serious injuries," he said.
Holiday periods also meant motorists were more likely to spend many hours behind the wheel and he warned fatigue could be deadly while driving, especially travelling unfamiliar roads.
"We all make mistakes some times, but mistakes on the road can have serious or even deadly consequences, so ensure your car is road fit, keep your speeds down, drive to the conditions and stay alert," Mr Zollner said.
Mr Zollner said one of the simplest measures to keep safe was to reduce speed.
Acting Assistant Commissioner road policing and prevention, Dave Trappitt, asked motorists this weel to stay safe by buckling up, driving sober and checking speeds.
"If you're out socialising, please take it easy on the alcohol, and look after yourself and your mates. This includes making a plan to get home safely, and not driving after drinking. We also know that a large number of assaults and family violence incidents have alcohol at the centre, while around a third of all fatal and serious road crashes have alcohol as the main contributor.
"Similarly, following a recent spate of diving related deaths, please take care out in the water and ensure you are well prepared with the right equipment and that someone knows your plans. The same applies if you're heading into the outdoors, so that you get home again safely."
St John Director of clinical operations, Norma Lane, said: "St John ambulance officers see first-hand the devastating effects of road crashes.
"We hope that making motorists more aware of the serious consequences of driving under the influence of alcohol or drugs, not wearing seatbelts, or a moment of distraction, will help to reduce the risk of road crashes this Easter. Please take road safety messages seriously and remember the principles of first aid, including looking after your own safety if you are first at the scene of a crash."
