What is the safest place in the pressure range to make a planned stop after a low-pressure warning?
- A.As soon as safely possible, while pressure is still above the spring-brake range and service braking is predictable
- B.After pressure reaches zero so the springs do the work
- C.Only at the originally planned destination
- D.After coasting until the vehicle slows by itself
Correct answer
A. As soon as safely possible, while pressure is still above the spring-brake range and service braking is predictable
Why
Stopping early keeps the driver in charge of where and how the vehicle stops. Waiting lets the springs choose the stopping place, possibly in a travel lane or on a grade.
