Thank you also works nicely.
It works but I'm not sure if this is correct for this public.

Code:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger) //test123
{
	if(vehicleid)
	{
		if(PlayerInfo[playerid][DrivingLicense] == 0)
		{
			SendClientMessage(playerid, -1, "You do not have a driving license, you decide to leave the vehicle!");
        	        ClearAnimations(playerid);
		}
	}

	return 1;
}

Or

Code:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger) //test123
{
	if(PlayerInfo[playerid][DrivingLicense] == 0)
	{
		SendClientMessage(playerid, -1, "You do not have a driving license, you decide to leave the vehicle!");
                ClearAnimations(playerid);
	}

	return 1;
}
