Driving in Subzero Conditions
Ireland’s winters are usually particularly mild and wet but 2025 has kicked off in subzero temperatures presenting road users with a unique set of challenges and risks. Here in DoneDeal we believe it is important that both the vehicle and driver are prepared for these harsh conditions and its crucial for our safety. Let’s have a look at how to manage these conditions, including the potential security risks associated with leaving your car running outside your house.
Vehicle Preparation
Inspect Your Tyres
One of the most critical aspects of driving in subzero conditions is ensuring your vehicle is equipped with good all weather tyres. Irish winters don't usually necessitate full winter tyres but if you are in a position to make the switch, you will experience better traction on icy and snowy roads. The rubber compounds in winter tyres remain flexible in low temperatures, allowing for improved grip. Failing this, ensure all weather tyres are fitted and in good conditon with ample thread.
Battery Health Check
Cold weather can significantly affect a car battery’s performance. It is good practice before winter sets in to have your battery tested to ensure it's in good condition. If your battery is more than three years old, consider replacing it as a precaution. This applies to electric vehicle owners also as there is a 12-volt battery to power ancillaries alongside the main power source battery.
Check Fluid Levels
Check and top off all essential fluids, including antifreeze, oil, and windscreen washer fluid. Use winter-grade oil if your vehicle's manufacturer recommends it, as it flows more easily in cold temperatures. Again some of this applies to electric vehicle owners also. Although EV's have fewer moving parts there is brake fluid, coolant and windscreen washer fluids to name but a few.
Inspect Windscreen Wipers
Replace your windscreen wipers if needed to ensure they can effectively clear snow and ice. Also, keep your windscreen washer fluid reservoir full with a fluid that won't freeze in low temperatures.
Does Your Car Have an Emergency Kit?
It is a good idea to equip your car with an emergency kit that includes a blanket, flashlight, secondary phone charger, food, water, a first aid kit, and jumper cables. This items can make all the difference should you be unlucky enough to breakdown or get stuck in snow.
Adapt Good Driving Techniques
The number one thing to do is slow down! Speeding in icy conditions is a leading cause of accidents. Drive slower than usual to maintain better control of your vehicle and increase your stopping distance: The stopping distance on icy roads is much longer than on dry roads. Increase the space between your car and the vehicle ahead to give yourself more time to react. Sudden movements should be avoided also because they can cause your vehicle to lose traction. Be gentle with the steering, acceleration, and braking to avoid skidding. Check the forecast before heading out. Adhere to the coloured warnings issued by Met Éireann. If the forecast predicts severe weather, consider postponing non-essential travel.
Security Risks of Leaving Your Car Running
Our DoneDeal offices have heard numerous reports opportunists taking advantage of cars left running outside of homes and businesses However tempting it may be to warm the vehicle up before driving, it does pose a significant security risk. An unattended running car is a prime target for thieves. It only takes a few seconds for someone to jump in and drive away, especially if the keys are in the ignition. This can then pose all sorts of issues with your insurance company, many of which, will be reluctant to pay out on a vehicle that was running. Where possible be with the car, if you have an electric car, familiarise yourself with the preconditioning heating settings.
To Summarise
We now know driving in subzero conditions requires preparation, patience, and an understanding of the risks involved. By taking the necessary precautions highlighted above you can ensure a safer and more secure winter driving experience. Always prioritise safety by preparing your vehicle, adopting cautious driving habits, and being mindful of the potential security risks associated with idling an unattended vehicle.
