The new DOT signs to honor loved ones killed on South Carolina roadways aren’t expected to significantly cut back on the number of homemade memorials, two College of Charleston sociologists said Thursday.

George Dickinson and Heath Hoffmann said roadside memorials are often highly individual expressions of grief that Americans are using more and more often as part of the mourning process. The sociologists co-authored a study on the topic that appeared last month in the British scholarly journal “Mortality.”
