Comparison to all vehicles.  This plot shows RSC safety scores on the horizontal axis vs. the number of vehicles with each safety score (depicted by bar height and percentages at the bottom). Colors reflect vehicle safety, ranging from red (not that safe) to green (safer). For reference, a score of 0 implies a 0.15% chance of driver death (13% chance of driver injury) over 15 years, and a score of 100 reflects a 0.016% chance (1.4% chance of driver injury). The 2018 GMC Terrain has a score of 79, implying a 0.043% chance of driver death (3.9% chance of injury). If equipped with optional advanced driver safety features, the chance of death falls to 0.038%, and the chance of injury falls to 3.4%.
