Hazard Lights in Rain: What South African Drivers Should Do

In heavy rain, use low-beam headlights, reduce speed and leave a much larger following gap. Do not use continuously flashing hazard lights as a substitute for proper lighting or safe driving. If visibility is too poor, leave the traffic stream and stop in a genuinely safe place.

Should you drive with hazards on in rain?

Hazard lights warn others of an unusual hazard, stopped vehicle or obstruction. While driving normally, all four indicators flashing can make turns and lane changes less clear. The safer combination is low-beam headlights, working rear lights, lower speed and more space. The AA advises drivers to use headlights in rain, avoid speeding and maintain a safe following distance.

What to do in a sudden downpour

Ease off the accelerator smoothly; avoid abrupt steering and braking.
Switch on low beams. Daytime running lights may not illuminate every vehicle’s rear lamps.
Increase following distance because wet roads lengthen stopping distance.
Use the demister and air conditioning to clear the windscreen.
Avoid standing or flowing water; its depth is difficult to judge.
If you cannot see safely, exit the live lane where lawful and safe, stop away from traffic, then use hazards.

When hazards are appropriate

Your vehicle has broken down or is stationary in an emergency.
You have pulled completely out of traffic because conditions are unsafe.
Your vehicle creates an unexpected obstruction.

Government travel guidance recommends pulling over safely, switching on hazards and calling roadside assistance during a breakdown.

Avoid these mistakes

Do not maintain normal speed because hazards are flashing. They do not improve grip or shorten stopping distance. Avoid high beams in heavy rain or fog because reflected light can worsen glare. Never stop in a live lane or low-lying place that may flood.
