Alcohol is legal, drunkenness is not
Unlike Saudi Arabia and Kuwait, Bahrain licenses alcohol in hotels and some restaurants — a large part of why the causeway is busy on Thursday nights. Drinking in public, being drunk in public and drink-driving are all criminal offences, and the drink-drive limit is zero.
Importing alcohol overland is illegal and the causeway is searched. Drug offences carry long sentences and deportation.
The causeway and driving
The King Fahd Causeway can back up for hours on Thursday evenings and Sunday returns, and during Eid it is worse. Bahraini roads are fast and aggressive by regional standards, with a high crash rate.
Summer heat regularly exceeds 45°C with very high humidity, which is a genuine medical risk rather than an inconvenience.
