Driving in bad weather

Rain, strong winds and fog are just some of the weather conditions that make safe driving more difficult, especially at night.

Minimising bad weather driving risks

To minimise the risks associated with driving in bad weather:

• slow down and drive at a speed appropriate for the conditions
• ensure the windscreen is clean and functional
• ensure the windscreen wipers are clean and working
• use the air conditioner or demister to keep the windscreen clear
• check all vehicle and trailer lights are working
• drive with the headlights on low beam in fog, and use the rear fog lights in heavy fog or hazardous conditions only
• use hazard lights when you are travelling very slowly and are likely to obstruct other vehicles
• watch carefully for other vehicles and road users
• increase your following distance to 4–6 seconds
• avoid sudden or harsh braking or steering actions
• do not attempt to overtake vehicles (except on a double carriageway)
• do not drive though roads covered in water.

Cruise control on wet and slippery roads

Cruise control ensures your vehicle maintains a constant speed. It’s particularly useful if you’re driving on open roads with reduced traffic flow and long distances between towns.

However, using cruise control on roads where you need to change speed frequently—such as windy, wet, or slippery roads—is dangerous and can increase the risk of an incident. The vehicle’s owner manual provides guidance about using cruise control.

Do not use cruise control:

• when traffic is heavy or the traffic volume varies
• on winding roads
• on wet and slippery roads.
