stock IsVehicleDrivingBackwards(vehicleid)
{
    new Float:Float[3];
    if(GetVehicleVelocity(vehicleid, Float[1], Float[2], Float[0]))
    {
        GetVehicleZAngle(vehicleid, Float[0]);
        if(Float[0] < 90)
        {
            if(Float[1] > 0 && Float[2] < 0) return true;
        }
        else if(Float[0] < 180)
        {
            if(Float[1] > 0 && Float[2] > 0) return true;
        }
        else if(Float[0] < 270)
        {
            if(Float[1] < 0 && Float[2] > 0) return true;
        }
        else if(Float[1] < 0 && Float[2] < 0) return true;
    }
    return false;
}
