It's important to obey all traffic signals, because they are in place for everyone's safety. Carelessly disregarding them can put the driver's life at risk, along with any passengers and other drivers on the road. Any car accident caused by violating any traffic laws can leave a driver liable for any injuries to anyone else.
When a hit-and-run accident occurs, the first thing a driver should do -- if he or she isn't injured -- is try to get the license plate number of the car that caused the accident. That and a vehicle description are the best pieces of evidence that police can use in tracking down the dangerous driver.
