Driving Safely
Domain 1: Driving Safely
The Nebraska CDL Passenger Driving Safely domain tests whether you can control a passenger vehicle and avoid trouble before it starts: pre-drive inspection, basic control and shifting, backing, visual search, communication, speed and space management, night and extreme-condition driving, hazard awareness, emergency maneuvers, skid control, accident procedures, and cargo/vehicle safety. The exam favors rules you can apply, not slogans.
Core rules
- Search 12–15 seconds ahead and check mirrors every 5–8 seconds; before any lane change, signal, check mirrors, and turn your head to check the blind spot.
- Use the passenger-vehicle following-distance rule: one second per 10 feet of vehicle length below 40 mph, plus one second above 40 mph. A 40-foot bus needs 4 seconds below 40 mph and 5 seconds above.
- Back only when necessary; use a spotter, back slowly, and stop when you lose sight of the spotter.
- On downgrades, select a lower gear before the descent; do not coast in neutral or with the clutch in.
- In a skid, ease off the accelerator and steer in the direction you want the vehicle to go; avoid hard braking.
Worked example
A 40-foot bus is traveling 55 mph on a two-lane highway. The minimum following distance is 5 seconds: 4 seconds for 40 feet plus 1 second above 40 mph. At 55 mph, one second covers about 81 feet (55 × 1.47), so 5 seconds is about 405 feet - roughly the length of a football field plus end zones. In rain, add more space; the rule is a minimum, not a target.
Traps that cost marks
Following a passenger car at a fixed two-second gap; checking mirrors after starting a lane change; braking hard in a skid; using cruise control on wet or icy roads; forgetting clearance height at bridges or canopies; and failing to scan for pedestrians when pulling away from a stop.
