More vehicle crashes happen at an intersection than other place on the road. You need to be very cautious when approaching an intersection. When you approach an intersection, first you need to slow down (not when you're already crossing it.) As you slow down and approach the intersection, look both ways and be ready to stop.
When you approach an intersection controlled by a traffic light, you must always be prepared to stop. If you do not witness the traffic signal change from red to green, then you must slow down and prepare to stop. When at an intersection where a red changes to green, always wait to ensure the intersection is clear of all traffic and pedestrians before proceeding. Look left, look right and look left again to be certain that cross traffic has stopped.
