GMC Sierra Owners Manual
Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the safety belt. See Safety Belts on page 3‑12.
• 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.
• Allow enough following distance between you and the driver in front of you.
• Focus on the task of driving.
