State Highway 1 through Bulls remains closed after a truck crashed into the RSA building at 8am.
The road is closed between Bridge Street and Criterion Street and a minor detour is in place.
Bulls fire chief Brian Carter said the southbound truck failed to take a bend before colliding with the RSA building, ripping of the frontage, as it drove along the curb.
The truck continued along High St before it jack-knifed and came to a stop at least 50m down the road opposite the library.
The two occupants of the vehicle were uninjured.
