MIWA cautions - Beware black ice a hidden winter danger on SA roads

 

Every winter, dozens of accidents on South African roads are linked to black ice, a hazard that often catches even experienced drivers off guard. Black ice is one of the most dangerous and often most misunderstood hazards motorists face in winter, warns Dewald Ranft, Chairman of the Motor Industry Workshop Association (MIWA).

 

“Many drivers assume black ice is a problem limited to colder countries,” says Ranft. “But it’s more common in South Africa than we realise, especially in high-altitude areas and inland regions like the KZN Midlands, Eastern Cape highlands, and Free State farmlands. If you’re travelling early in the morning or after a cold front, it’s a real risk.”

 

Despite its name, black ice isn’t black. It’s a thin, transparent sheet of ice that blends in with the road, often making the surface appear merely wet. It reduces tyre friction by up to 70%, and even experienced drivers may not realise they’re on it until they lose control. You should particularly watch out for black ice on bridges and overpasses (they freeze first); shaded or low-lying areas; early morning or evening drives and after light rain followed by freezing temperatures. “You might notice the road looks wet but there’s no spray from other tyres - that’s often a clue,” says Ranft. “If there’s frost on your windscreen, chances are the road could be icy too.”

 

If you suspect black ice:

•    Slow down and drive cautiously

•    Avoid sudden steering or braking

•    Leave a greater following distance

•    Keep your headlights on for visibility

•    Never use cruise control in icy conditions

 

Ranft says preparation is key. “Your tyres and brakes are your first line of defence. If your tyres are worn or under-inflated, or your brake system isn’t functioning optimally, you’re much more vulnerable. Safety doesn’t come from luck - it comes from preparation.”

 

He advises motorists to book a winter safety check at a MIWA-accredited workshop.

These checks typically include:

•    Tyre tread and pressure inspection

•    Brake pad, disc, and ABS system check

•    Battery, wiper blade, and fluid checks

•    Light functionality assessment

 

“These small checks can make a big difference. Black ice doesn’t give second chances,” concludes Ranft. “Let’s stay safe out there.”
