You can use GetJointTranslation, as mentioned at the end of the section about limits here: http://www.iforce2d.net/b2dtut/joints-prismatic

• Checking if a joint is currently at one of its limits is pretty simple:
  bool atLowerLimit = joint->GetJointTranslation() <= joint->GetLowerLimit();
  bool atUpperLimit = joint->GetJointTranslation() >= joint->GetUpperLimit();
