Number one rule….pay attention. Train yourself in the art of paying attention. Don’t use a signal out of habit, use it when you should, to alert people of what you are doing. Don’t use it when you don’t need it. Sitting in a left turn lane, waiting to turn left? Don’t need it. Sitting on a 2 lane road waiting to turn left? Need it, and use it.
One of my biggest pet peeves is people who jump into the left turn lane, throw on their right blinker and expect someone to let them in, because they can’t drive correctly. I never let them in, because I don’t want a stupid driver who doesn’t know how to drive in front of me. If they can’t handle pulling out into traffic safely, who knows what else they don’t know.
Always run blocker for a semi, if he needs to get over to clear a lane for merging traffic, back off and give him a flash, he will return the favor in kindness.
Drive like you’re on a motorcycle, and be aware of others all the time. Watch peoples front rims, if it’s turning, there’s danger.
