The dreaded Right Hook: Where a driver passes by on the cyclist's left and then makes a right hand turn, oblivious to the fact that the cyclist was there and had to be yielded to. A study by University of Toronto Engineering found that drivers often fail to adequately scan for non-motorists when they turn right at intersections. In fact, more than half of 19 participants aged between 35 and 54 years old were guilty of this.
