Ah.. Maybe try use these 2 stock(s), would be much better.

PHP код:

stock IsAPoliceVehicle(vehicleid)
{
     switch(GetVehicleModel(vehicleid)) 
           {
            case 598, 599, 523: return 1; // You can add more vehicles id if u add more cop vehicles.
           }
           return 0;
} 


PHP код:

stock IsAParademicVehicle(vehicleid)
{
     switch(GetVehicleModel(vehicleid)) 
           {
            case 416: return 1; // same applies here.
           }
           return 0;
} 


Your final code should be this and should be working. (Haven't tested it but looks fine for me.)

PHP код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger) 
{ 
    if(IsAPoliceVehicle(vehicleid)) 
    { 
        if(PlayerInfo[playerid][pFaction] != 1) 
        { 
            ClearAnimations(playerid); 
            GameTextForPlayer(playerid, "~r~Nu esti autorizat sa conduci aceasta masina!", 1000, 3); 
        } 
        else return InCopCar[playerid] = 1; 
    } 
    else return InCopCar[playerid] = 0; 
  
    else if(IsAParademicVehicle(vehicleid)) 
    { 
        if(PlayerInfo[playerid][pFaction] != 2) 
        { 
           ClearAnimations(playerid); 
           GameTextForPlayer(playerid, "~r~Nu esti autorizat sa conduci aceasta masina!", 1000, 3); 
        } 
        else return InParamedicCar[playerid] = 1; 
    } 
    else return InParamedicCar[playerid] = 0; 
  
    return 1; 
}
