The chance of dying in a car accident is only 1 in 100 over my lifetime, so, it might as well be nothing... Well, 115 children in the US are abducted by strangers, sexually assualted and murdered every year. 115 yearly. That isn't an urban myth.
When driving in residential areas you should signal around 30 meters (100 feet) in advance of making a right or left turn. This is assuming there are no other turns on the same side of the road before the turn you intend on taking, else you will need to signal after this turn. For high speed roads this distance increases. 70 mph dual carriageways for instance, signalling should start from around 275 meters (900 feet) from your exit.
9. Watch left turn signals for traffic traveling in your direction. If you have a green light, and the turn signal facing you just turned green, and there are still cars turning, your green light may be 'fresh' enough to make.
