RAA is urging safety on the state’s roads ahead of a wet and windy June long weekend – especially for those travelling throughout the regions.

The Bureau of Meteorology has forecast showers and high winds over the weekend and a possible thunderstorm on Monday 9 June for the southern Fleurieu Peninsula and Kangaroo Island.

RAA says crash data shows drivers are more likely to hit roadside objects like trees and stobie poles in wet conditions – with ‘hit fixed object’ crashes accounting for 44 per cent of all wet weather crashes on high-speed roads.

This compares with 28 per cent of dry weather crashes on those roads.

Pedestrian crashes resulting in a serious injury or fatality increase by 43 per cent during winter compared to the rest of the year.

In the five years between 2019-23, 130 crashes resulted in a pedestrian being seriously injured or killed during winter.

RAA Senior Manager Road Safety Charles Mountain says drivers hitting the road for the long weekend should prepare for longer stopping distances and lower visibility.

“The June long weekend brings with it additional challenges on our roads,” Mr Mountain says.

“When the road is wet, the proportion of crashes involving drivers losing control and hitting roadside objects increases, so take extra care if you’re behind the wheel.

“Cyclists and pedestrians should use designated crossing facilities where available to ensure they’re seen from a distance.

“Make sure you turn your headlights on if it’s dark or the rain is reducing visibility don’t rely on the auto –on function.

“Drive to the conditions and reduce your speed when there are potential hazards like curves or people near the road.”

Mr Mountain says now is a good time to conduct some vehicle checks including headlights and tail lights, tyre tread (at least 1.5mm across the entire tyre width), windscreen wipers and engine oil.
