Having a hiab “ticket” won’t do you very much good at all without the requisite experience.
Having your ADR Driver Training Certificate is generally enough to get the extra work, nowhere near as much “experience” needed, especially doing curtainsider work with packages: as long as you can secure your load and know what needs to be kept segregated from non-compatibles, you’ll be fine.
And… doing ADR can get you most of your DCPC hours for your next DQC.
However, check to see what work is available in your area, there may or may not be much ADR available.
