PHP код:

ClearAnimations(playerid); 


Have you try this one? put it in OnPlayerEnterVehicle It's worked fine for me
Should be like this:

PHP код:

if(!LicenseTest[playerid])
{
    SendClientMessage(playerid, COLOR_ORANGE, "You are not taking a drivers license test.");
    ClearAnimations(playerid);
}
