A marinetraffic recording, showing an example of how the passage through the Strait of Hormuz works now.

Vessels are hugging the Iranian coast instead of taking the standard route through the center of the Strait, with some reports suggesting Iran charges a fee for passage.

Techically speaking, charging a fee is illegal in this situation. The Strait isn't a canal and it's not located entirely within Iranian territorial waters. But who cares about international law these days? This maritime toll gate is the result of its malfunction.
