Avoid making left hand turns across busy intersections that don't have turn signals. It takes a while to learn how to gage the oncoming traffic. Better to go down a block or two until you come to a light, or plan a route that doesn't need this turn.
Don't make assumptions about what other drivers are going to do. The only thing you can assume about another driver with a turn signal on is that he has a turn signal on. He might not be turning at all and forgot to turn it off the last time he used it or has changed his mind.
When there's an obstruction in your lane, wait for oncoming traffic to clear before you pull around. Just because someone's blocking your lane doesn't mean you have the right of way in the next or oncoming lane.
Watch out for aggressive drivers and try to stay out of their way. They are the cause of a
lot of accidents--especially on the beltways.
Watch out for anything that is connected to the U.S. Mail. (This tip submitted by someone who has had run-ins with a mailbox and a mail delivery station wagon, and a fender bende
r in front of the post office.)
Don't do anything that will cause another car's driver to slam on the brakes such as pulling
out in front of him or swerving into his lane.
