You could always make a variable...

pawn Код:

#define IsPlayerDead(%0) PlayerIsDead[%0]
new bool:PlayerIsDead[MAX_PLAYERS];

OnPlayerDeath - PlayerIsDead[playerid] = true;
OnPlayerSpawn - PlayerIsDead[playerid] = false;
OnPlayerDisconnect - PlayerIsDead[playerid] = false;

If the player then they can't be in a vehicle pretty simple.
