Drive extremely carefully when the roads are icy. Avoid sudden actions as these could cause loss of control.
drive at a slow speed in as high a gear as possible; accelerate and brake very gently
drive particularly slowly on bends where loss of control is more likely. Brake progressively on the straight before you reach a bend. Having slowed down, steer smoothly round the bend, avoiding sudden actions
check your grip on the road surface when there is snow or ice by choosing a safe place to brake gently. If the steering feels unresponsive this may indicate ice and your vehicle losing its grip on the road. When travelling on ice, tyres make virtually no noise.
