Defensive driving means "always expect the unexpected." The first step in driving defensively is to wear your safety belt -- See Safety Belts: They Are for Everyone .
Caution: Assume that other road users (pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready. In addition:
• | Allow enough following distance between you and the driver in front of you. |
• | Focus on the task of driving. |
