Only cross at a marked crosswalk or intersection. Many accidents occur because pedestrians cross the street in areas where drivers are not expecting to see them. If there is no marked crosswalk available, the state of Washington deems every intersection to be legally considered a crosswalk where drivers must stop for pedestrians. If you are injured while crossing in a crosswalk, you'll have the law to protect you.
Make Yourself Visible
Visibility is a huge factor that can either cause or deter an accident. If you're wearing dark clothing and crossing an intersection at night, you put your self at a much greater risk of being involved in an accident than if you were wearing reflective, light-colored items. Other ways you can make yourself more visible to drivers is to carry a flashlight with you at night and try to make eye contact with drivers so you can be sure they see you.
If you're walking with children, make sure they are visible as well and that they hold your hand while crossing the street. They should not be allowed to cross the street by themselves, nor should they play near a busy street or intersection.
If you are utilizing an umbrella in rainy weather conditions, you'll still need to make sure that approaching vehicles can see you. The rain will make it even harder for drivers to spot you so try to wear a bright raincoat to stand out.
Look Both Ways
This is perhaps the most obvious way to avoid being involved in an accident, and it's a rule that is normally ingrained in one's head since childhood. Not only should you look left and right before crossing the road, but you should double check and look both ways once more. You can alert drivers that your intention is to cross the road, by waiting at the edge of the curb and look alert. If you're gazing around aimlessly, drivers will assume you're not yet ready to cross the street.
Don't Drink and Walk
It may sound like a joke, but drinking and walking can be actually be very dangerous. Of course, you should always choose to walk instead of drive if you are inebriated, but you may still have poor judgment that will cause you to cross a busy road without even looking. If you are under the influence of drugs or alcohol, be aware that you are still putting yourself at risk of being in an accident.
Obey Traffic Signals
Not only should you only cross in marked crosswalks and intersections, but you should wait for the proper traffic signals before crossing. If you cross against a red "do-not-walk" sign and are hit by a car in the process, you will be held accountable in the eyes of the law. Unless an officer is directing traffic flow against the signals, wait for your turn.
