Some useful tips for winter driving from Paddy Comyn at CompleteCar.ie here.
When it comes to driving safely on Icy roads Paddy advises motorists to decrease speed and leave plenty of room to stop.
You should allow at least three times as much space than usual between you and the car in front. Brake gently to avoid skidding & if your wheels start to lock up remember to ease off the brakes.
Turn on your lights to increase visibility to other motorists & keep your lights and windscreen clean.
Use engine braking where possible and be careful on bridges, overpasses and infrequently travelled roads as they will freeze first. Even at temperatures above freezing, if the conditions are wet you might encounter ice in shady areas or on exposed areas like bridges.
Don't assume your vehicle can handle all conditions. Even four-wheel and front-wheel-drive vehicles can encounter trouble on winter roads.
