Possible Solutions

Each of the 1997 focus groups was asked to take a few minutes and discuss possible solutions for the one or two crash causes most members of the group had ranked among the three most serious causes. Three groups discussed solutions to speeding, two addressed aggressive driving, two discussed unsafe lane changing, and two discussed how to deal with bad weather. Inattentiveness, truck blind spots, and driver training also were topics of brief problem solving sessions.
