Is it dangerous to drive with bad rear struts on my 2007 Nissan Altima?

a 2007 altima does not have rear struts. it has shocks and coil springs. if the rear shocks are bad and the car is bouncing up and down several times when you hit dips in the road or after you come to a stop your shocks could be bad and then yes it could cause you to wreck in certain situations. to test your shocks bounce the rear by pushing up and down several times real hard on each corner. after releasing the car it should only bounce 1 1/2 to 2 times before stopping. any more than this and the shocks may be bad.
