Max & min speed limit, what is aggresive driving

Posted by request.
According to Commonwealth Law at DMV's site:

Speed Limits

A speed limit is the maximum legal speed you can travel on a road under ideal conditions. You may drive slower than the posted speed, but it is illegal to drive any faster. By law, you must drive slower if conditions make the posted speed unsafe. It is illegal to use a radar detector in Virginia. However, you may legally possess one if the device has no power source and no one in the car can access it.

Aggressive Driving

Aggressive driving is becoming a growing issue in Virginia, but, just what is aggressive driving? We've all seen it. It's the driver who speeds, weaves in an out of traffic, doesn't use turn signals and uses "hand gestures" that are less than polite.
