Winter driving safety requires adapting to increasing seasonal hazards like black ice, fog, and heavy rain. To mitigate risks, the Automobile Association (AA) recommends increasing following distances by up to 10 times on icy roads and maintaining a four-second gap in the rain to ensure control and prevent crashes.
How can motorists handle black ice and slippery surfaces?
As temperatures drop, South Island police have urged motorists to exercise extreme caution following a series of recent crashes on icy roads. The primary challenge involves black ice, which AA motoring advisor Ryan Bos describes as “one of the biggest hidden dangers on our roads.” Because this thin layer of ice matches the color of the tarmac, it is difficult to detect until a vehicle loses traction.
To manage these conditions, the AA advises drivers to increase the gap between their vehicle and the car in front by up to 10 times the recommended distance. Drivers should also remain extra vigilant on shaded stretches of road, including bridges, flyovers, and tunnels, where ice is more likely to form.
If a vehicle begins to skid, the AA recommends keeping the vehicle moving and looking in the direction you intend to travel. Drivers should take their foot off the accelerator but must avoid slamming on the brakes. According to the AA, sudden braking can upset the vehicle’s balance and make it harder to regain control.
What are the safety protocols for fog and heavy rain?
Visibility becomes a critical factor as fog and rain become more frequent. The New Zealand Transport Agency (NZTA) advises keeping all windows and mirrors clean to maintain clarity. If windows fog up, drivers should use the demister or open a window to clear the view.
When driving in fog, motorists should dip their headlights to prevent light from reflecting back at them. Using only park lights is discouraged, as they offer poor visibility and are difficult for oncoming drivers to see. While fog lamps can be used, the government warns that using them in clear weather is illegal and can result in an infringement fee of $150 or a maximum penalty of $1000.
Rain presents different challenges, specifically regarding hydroplaning. The Government’s Drive website recommends maintaining a four-second following distance in the rain and looking 12 seconds ahead to spot large puddles. Ryan Bos told 1News that hitting a large puddle at high speeds can cause a car to lose its grip on the road.
To maintain focus during difficult conditions, Bos suggests limiting distractions. This may include turning down the radio or pausing conversations with passengers. If driving becomes overwhelming due to traffic or poor conditions, Bos recommends pulling over for five to ten minutes rather than continuing to drive.
Why is winter vehicle maintenance essential?
Preparation is a key component of winter road safety. The AA suggests using the colder months to have vehicles serviced and to ensure all lights are functional. Battery health is a particular concern, as the cold requires more power to operate vehicle electronics.
Tires also require closer inspection. Drivers should ensure that each tire has equal pressure and sufficient tread depth to handle slippery surfaces. If a vehicle has been stationary for a period, the AA recommends taking it for a test run the night before expected travel to confirm everything is working correctly.
Managing frozen windshields also requires specific care. While it may be tempting to use hot water, the AA warns that you should never use boiling water on an icy windscreen as it can cause the glass to crack. Instead, drivers should use a plastic scraper, a debit card, or pour cold water over the ice.
Frequently Asked Questions
What should I do if my car starts to skid on ice?
Avoid slamming on the brakes. Instead, take your foot off the accelerator, look in the direction you want the car to go, and avoid sudden movements to help regain control.
Is it legal to use fog lamps at night?
Fog lamps can be used in foggy conditions, but using them in clear weather is illegal and can result in a fine of up to $1000.
How can I prevent my windscreen from cracking when defrosting?
Never use boiling water. Use a plastic scraper, a debit card, or let the engine run with the heater on to defrost the glass safely.
What should I pack if I get stuck in the snow?
The AA recommends packing a mobile phone with a charger, a bottle of water, warm clothes, snacks, and a blanket.
