Bus overtaking in a dangerous manner

On the night 3 Dec 2010 while driving from Johore to KL, there were few buses driven at about 110kmph and overtaking slower lorries, especially on the 2-lanes towards Malacca (3-lanes from Malacca to KL). Nealy all these buses overtook lorries with sufficient notice and safe distance to other road users, thus I do not have problem with their speeding. Unfortunately, there was one bus (body painted red, company name start with DE.....) which tended to overtake with very short notice, practically forcing other cars to slow down quickly behind it. My daughter in my car said this bus company was involved in the recent tragic accident in Malacca which killed many passengers. I was surprised as I thought this bus campany was suspended, unless the suspension only applied to MALACCA route!!
