Space margins refer to the amount of space between you and other road users, and following distance is something that is measured between you and the vehicle in front of you. Leaving adequate distance within this space plays an important part when utilizing the see-think-do driving strategy. Giving yourself enough following distance means that you will have enough time to see hazards, think about what your options are, and react accordingly. When you follow too closely to road users ahead of you, you may not have enough time to react and respond to hazards or incidents.
