Dear Sh. Dinesh Shah Ji,
The bus being public conveyance under Rule 138(2), last time I had the same query with no answers regarding how to fill vehicle details. Thought of making representation to the government but couldn’t do that. Sir, you need to generate E-way Bill but Part B remains the issue.
Don’t follow: Best possible solution, generate E-way Bill and fill Part A (as the law requires you to generate E-way Bill before the commencement of movement). Get on the bus, fill Part B manually along with the time (the moment you fill in the vehicle details, the E-way Bill becomes valid as per explanation 2). It shouldn’t be like this, but what other options do we have?
Regarding the metro, it runs on a motor, so 138(14) is out of the question. Interestingly, road or railways situation is contemplated by rule 138, they haven't contemplated situation like metro (though a public conveyance but runs on rail, not road). So, if you walk (non-motorised) till the metro station and thereafter from the destination metro station walk (or take cycle, cycle-rickshaw, bullock cart, horse and the likes of NMC) to the place of the recipient then no need to generate E-way Bill. And during the entire journey if the employee takes tempo, then you will face the wrath of 129.
Fun query :)
