Although our winters are relatively mild compared to other countries, there are still a number of checks and driving practices that motorists should keep in mind to ensure the safety of all users out on the road.
The cold months in South Africa can mean heavy rainfall in the coastal regions, thick mist in the lowveld, light snow further inland, and sub-zero temperatures that can affect the performance of your car, all of which are important factors to bear in mind before setting out on any journey throughout the middle of the year.
Vehicle checks and preparation
Drivers should pay attention to the condition of the various components and fluids in their vehicle before setting off, according to Arrive Alive.
If you live in a particularly cold province that experiences below-zero temperatures, check your coolant and antifreeze levels to ensure that the engine will start when you turn the ignition.
Also ensure that you have enough engine oil and brake fluid, as the viscosity of these substances is affected by the temperature.
Before setting off on your trip, check that the heater and defroster are working to clear the windscreen, and that the wiper and washers are in good condition as the sun’s lower position in the sky creates dangerous glare that is magnified by a dirty windscreen.
Working lights and tyres with sufficient pressure and tread are crucial regardless of the time of year, but they are especially important in winter where there is reduced visibility from mist and shorter days, and where the tyre’s tread is vital for traction in slippery conditions.
Finally, Dekra recommends that motorists always travel with a spare wheel and safety equipment in the boot, including a reflective triangle, a small fire extinguisher, and an emergency kit with a flashlight, jumper cables, a first-aid box, blankets, and non-perishable food.
Driving techniques
In winter, it’s best to set off slowly to give the powertrain a chance to warm up, as the cold fluids are not as effective at lubricating the components and the brakes are not as responsive.
If the road surface is wet, increase your following distance to around five to six seconds as vehicles can hydroplane when braking, and cars with trailers can potentially jack-knife, according to Supa Quick.
Pay attention to severe winds, as these have the potential to flip over larger objects such as vans, trucks, and trailers. For this reason, avoid overtaking trucks in these conditions and pull over if the wind speed becomes hazardous.
Avoid driving in flowing water and deep puddles wherever possible, though if it is unavoidable you should switch to a lower gear and move slowly while gently pressing on the brakes, as this prevents mud, sand and water from getting into the brake drums or discs.
Maintain the engine revs and cross the water, and continue to apply light pressure to the brakes when you reach the other side to dry them out as quickly as possible.
