We’ve all heard it a thousand time: “Look both ways before you cross the street!”. But how many people really obey this simple rule? According to the Federal Highway Administration, about 100,000 pedestrians (people traveling on foot) are hit by cars each year. It is one of the leading causes of accidents death for children. So how can you be safe when you are walking? Follow these simple rules offered by the National Highway Traffic Safety Administration:

• Always walk on the sidewalk. If there is no sidewalk and you have to walk in the street, always walk on the side that allows you to face oncoming traffic.

• Wear bright color. You want drivers to be able to see you. If you must walk at night, be sure to wear reflective clothing or tape so that drivers can see you.

• Cross the street only at marked crosswalks or conners and always stop at the curb before crossing. Look both ways (left, then right, then left again). If you see a car coming, wait for it to pass. Keep looking for cars as you cross.

• Walk at good pace. Never run
