Winter frost and ice can make roads slippery. Adjust your speed: Slow down and avoid sudden braking or turning.
We're due for very cold overnight temperatures at or below 0ºC this week, particularly on Wednesday and Thursday. These are the perfect conditions for slippery roads in the morning.
Black ice forms when temperatures are at or below freezing (0ºC) and light rain falls on the road, and it can also form when water already on the road freezes when temperatures fall below freezing point.
You can't easily see black ice, but what you can do is travel to the conditions:
• Slow down. Adjust your speed to suit the conditions.
• Increase your following distance to people ahead of you.
• Avoid sudden braking or turning to reduce the risk of sliding.
• Be careful in areas shaded from the sun – they'll stay slippery for longer.
Watch out also when you're travelling over bridges – they get icy before the normal road around them, and they stay icier for longer than the rest of the road.
Turn your headlights on dipped if it's raining. Many of us have silver, grey, or white vehicles which easily blend into the road, grey sky, and the rain. Having your headlights on dipped activates your rear position lights. Together your lights make you much more visible to people behind you and people coming towards you.
When the weather is bad, always check our page to see if state highways are affected before you travel. Follow us if you aren’t already.
