I also wanted to take a E driving license aka motokar BTM melebihi 7500kg. I think around RM4k the costs.

If E definately is commercial vehicle. So either GDL for lorry pr PSV for bus.

Lorry have to choose KEJUR (non-trailer) or SENDI (trailer)

Exempted from Undang test but still have to take GDL or PSV and practical test.

If get E license and GDL or PSV, what to do with it? Can't buy a huge lorry or bus to use as daily car usage. Unless your company is engaged in logistic services or public transport. Then you can have fun driving it.
