CDL · Tank vehicles
A tanker driver comes to a curve or a freeway ramp that has a posted speed. How fast should the tanker go through it?
Correct answer: Much slower than posted, because a tanker can overturn even at the posted speed.
Answer options
- ASlower only on exit ramps; curves and entrance ramps are fine at the posted limit
- BMuch slower than posted, because a tanker can overturn even at the posted speed Correct
- CRight at the posted speed, because those limits are set with tankers in mind
Why
A tanker's high center of gravity means it can overturn on a curve even when the driver stays at the posted speed, as testing has shown. Slow to a speed well under the posted figure for curves, on-ramps, and off-ramps.
