A support frame (44) and method are described herein for support of a wind turbine blade (22) on a vehicle during transport to an installation site. A load indicator (46) is provided adjacent one or more support pads (52) when using the support frame (44), with the load indicator (46) being configured to determine and communicate an amount of movement of the wind turbine blade (22) relative to the support frame (44) during initial loading into the support frame (44) and during transport. To this end, the load indicator (46) helps assure that the wind turbine blade (22) is properly loaded into the support frame (44) in a desired transport position, while also confirming whether significant shocks or other movements have occurred during transport that could lead to a higher likelihood of internal or external damage at the blade (22).
