On a very icy day, you see blue lights from an emergency vehicle in your mirror as you drive along a frosty residential road. What should you do to let it pass safely?

Explanation

The Highway Code Rule 231 says that on icy roads you must drive extremely carefully and avoid sudden actions such as harsh braking, sharp steering or rapid acceleration, as these can cause loss of control. When an emergency vehicle approaches, you should still follow this advice: slow down gently and pull in smoothly only when it is safe to do so. Sudden braking or swerving, even to help an emergency vehicle, can cause a skid and create more danger.
