According to the CDL Manual's following-distance guidance, what adjustment should be made at speeds above 40 mph compared to the base rule used below 40 mph?
A. Reduce the following distance since higher speeds already increase spacing between vehicles
B. Add one additional second of following distance for extra safety margin
C. Cut the following distance in half to keep pace with traffic
D. No adjustment is needed above 40 mph
Show answer and reasoning
Correct answer: B. Add one additional second of following distance for extra safety margin
A: Reducing following distance at higher speed runs opposite to the safety margin the rule is designed to build in.
C: Higher speed increases stopping distance, which is why an additional second is added rather than removed.
D: The manual specifically calls for an added second above 40 mph rather than leaving the rule unchanged.

B. Coasting in neutral for several seconds before every shift
C. Riding the clutch continuously between shifts
D. Shifting only while the vehicle is stopped
Show answer and reasoning
Correct answer: A. Double-clutching
B: Extended coasting in neutral is not the described shifting technique and reduces vehicle control.
C: Riding the clutch causes premature clutch wear and is specifically discouraged.
D: Shifting only while stopped is not how on-the-move gear changes are performed in a moving vehicle.
