You must signal for at least 3 seconds before moving left or right. It's the law.
That means signalling for at least 3 seconds before turning, changing lanes, pulling out from a kerb or parking space, or otherwise changing direction.
This is especially important in winter. Visibility is reduced in bad weather. People around you need to understand what you’re doing so they have time to adjust their speed – especially on slippery roads.
Signalling around roundabouts is different. As you can see in section 3.10(5), the law doesn't state a minimum time you must signal at roundabouts. That's because some roundabouts are small. But the law still requires you to at least show a signal so everyone else knows the direction you’re travelling.
When the weather is bad, always check our pages to see if state highways are affected before you travel. Follow us if you aren’t already. You can find more information in this post: https://www.facebook.com/share/p/1CmQR6EXxn/
