Sounds like it was a long old day but I imagine you’ve come away from it a much better driver. Sometimes the best way to learn is from your mistakes.
There is a bit of a nack to the self tipping at aldi with the electric pallet trucks. It will come with time and you’ll know how to do it after a while without knocking a pallet over.
As for the bridge thing. I can’t stress enough; invest in a “truckers atlas”. They show all of the bridge heights on major roads and a quick glance can often highlight and eliminate problem areas on a route. Alas, well done on getting yourself back out of it. Many a plankton would have risked it or not even noticed the thing was too low in the first place.
