Negotiating traffic in the occupied West Bank can be difficult, with constantly shifting Israeli roadblocks and security checkpoints. There is added complexity as there are some roads and settlements only Israelis are allowed to enter.
Palestinians in the past have relied on Facebook groups and word-of-mouth to anticipate West Bank traffic and closures.
