Mirrors must be checked continuously while driving — not just before lane changes. Every commercial vehicle has significant blind spots on both sides, directly behind, and directly in front at close range. Adjust mirrors before every trip. Know where your blind spots are and compensate by increasing scan frequency and GOAL usage.
Straight trucks (18–26 ft) have a wider turning radius than passenger vehicles. The rear wheels track inside the front wheels on turns (off-tracking). This means you must swing wider on right turns to avoid curbing or striking objects on the inside of the turn, be aware of the tail swing on the outside of the turn, and check mirrors through the entire turn — not just at the start.
Stay centered in your lane. Avoid riding the line on either side. When passing parked vehicles or pedestrians, create a buffer of space without drifting into oncoming traffic. On narrow streets, slow down and be prepared to stop.
Maintain a minimum 4-second following distance under normal conditions. Increase to 6–8 seconds in rain, fog, heavy traffic, or unfamiliar areas. A loaded truck takes significantly longer to stop than a passenger vehicle.
Posted speed limits are maximums for ideal conditions. Reduce speed for wet or icy roads, fog or reduced visibility, construction zones, residential areas, parking lots, and any area with pedestrian activity. If conditions change, your speed must change with them.
Scan 12–15 seconds ahead of your vehicle at all times. Look for vehicles pulling out, pedestrians stepping off curbs, brake lights ahead, traffic signal changes, road debris, construction zones, and emergency vehicles. Anticipate what other drivers might do — not just what they're doing now.
Intersections are high-risk zones. Approach with caution even when you have the right of way. Scan left-right-left before proceeding through any intersection. Watch for red-light runners, turning vehicles, and pedestrians in crosswalks. Yield right-of-way when in doubt.
Reduce speed immediately upon entering a work zone. Follow posted signs and flaggers. Increase following distance. Be prepared for sudden lane shifts, narrow lanes, and workers on foot.
