What is Iran's 'toll booth' system on Strait of Hormuz?

Iran's IRGC has imposed a 'toll booth' system at the Strait of Hormuz, rerouting ships from the normal mid-strait channel into Iranian waters near Qeshm and Larak islands. Vessels must submit cargo and crew details, clear a vetting process, and get IRGC escort. At least two ships reportedly paid $2 million each, while countries like India secured free passage diplomatically.
