Military checkpoints such as the one illustrated above allow vehicles with Israeli registration plates through, but some roadblocks block all traffic apart from pedestrians. Palestinian-registered vehicles are not usually allowed to leave Palestinian areas.

Either way, most Palestinians take a shared taxi to the checkpoint, walk across it, and pick up another taxi on the other side.

This has significantly increased the cost of travel for Palestinians. Taxis often take tortuous routes through Israeli-controlled areas to avoid other roadblocks, pushing up prices further.

Lorries delivering food and other supplies are also allowed to pass through military checkpoints, though sometimes with lengthy delays which can cause cargoes of fresh produce to spoil.
