Home › CDL Practice Tests › Combination Vehicles Questions › Question 62
For a single semi-trailer combination, what rearward amplification figure is commonly cited in CDL study material?
- A.About 0.5
- B.About 2.0, meaning the trailer feels about twice the lateral force of the tractor in a rapid maneuver
- C.About 1.0, exactly the same as the tractor
- D.About 5.0
Correct answer
B. About 2.0, meaning the trailer feels about twice the lateral force of the tractor in a rapid maneuver
Why
CDL material uses about 2.0 for a single trailer to make the crack-the-whip point concrete. Even an ordinary single therefore rolls more easily than the tractor pulling it.
