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.
I would advise good common sense to look at the total picture of, location, traffic volume, speeds and highway conditions. Minnesota law states: âA signal of intention to turn right or left shall be given continuously during not less than the last 100 feet traveled by the vehicle before turning.â.
