Questions about example sentences with, and the definition and usage of "Drivers"

A: In this sentence, "up" means "fast".

Yes, it sounds natural.

A:

Yes, there is a subtle difference. There actually can be several subtle differences.

For example:

The first one "Drivers are not supposed to go over the speed limit." <--- This wording, without any emphasis on any of the words, is used more likely by someone who likes to follow rules and also likes it when other people follow rules as well.

The second one "Drivers should not go over the speed limit." <--- This wording, (again, without any emphasis on any of the words) is going to be used by someone who's more casual about following rules than the the person that might say the first sentence.

---

But... if we had emphasis to any of the words, this can drastically change the meaning of either sentence:

In the first sentence:

"Drivers are not SUPPOSED to go over the speed limit." <--- Adding emphasis to "supposed" now possibly changes the meaning to "Drivers are not supposed to go over the speed limit but do anyway".

In the second sentence:

"Drivers should NOT go over the speed limit." <--- Adding a subtle emphasis to "not" now turns the second sentence in the one said by a rule follower.

---

Both sentences are getting the same idea across, but the WAY they are said will account for all subtle nuances.

Grounding is for trucks dealing with flammable materials like propane and gas.

Basically, the static electricity comes from the human body, not the vehicle. The spark can ignite fuel on the vehicle and explode.

Drivers use a ground connection and insert it into a grounding station. Not sure if you can only use the earth for grounding your vehicle. I just know there was strict laws and procedures on how to do this correctly.

It is required by law for drivers transporting flammable materials. It’s not just trucks but also trains as well.
