No, the rule below still applies to any combat situation. If you do accidentally hit someone with your car while in combat and see that they are lay on the floor in the vdm script then leave them be until they have gotten back up and moved themselves from that position. If they decide to shoot at you right after the vdm script has ended then I'd say feel free to shoot back.
[SIZE=medium](2.1) Vehicle Deathmatch (also known as VDM) - Using any vehicle as a weapon (e.g running people over, causing explosions including while sling loading, ramming, etc), will result in you receiving a ban. Three vehicles are excluded from this, MRAPS (Ifrits, Hunters and Striders) can ram other MRAPS in order to disable them, yet not to kill the passengers. This is allowed as these vehicles are the only vehicles ingame that can withstand being rammed. Please note that you need to initiate roleplay before attempting to ram an MRAP. (Please note - MRAPS don't need to be initiated on in the redzone) This is to prevent random ramming on site. (Three minutes of chasing also constitutes initiation of MRAP and MRAP ramming).[/SIZE]
