Before you start

A valid Iqama
Your original, unexpired foreign licence
Confirmation that the issuing country is on Muroor's approved list
An active Absher account with the app installed

Step-by-step

1
Check the approved-country list before anything else
Muroor's list — commonly described as around 47 countries, including the US, UK, EU states, Canada, Australia, New Zealand and the GCC — determines whether you skip the road test entirely. It is bilateral and changes, so verify through Absher or Muroor rather than a forum post from a few years ago.

Get the certified Arabic translation
A licensed translation office produces it; your original licence alone will not be accepted. Khobar has several accredited offices near the traffic department. Carry the original and the translation together to every appointment.
In personWho: YouSame day to a few daysRoughly SAR 100 and up
3
Complete the Efada medical
An approved centre tests eyesight and colour vision and draws blood to record your blood group, which is printed on the licence. Results transmit electronically into Absher — you carry no paper. There is no exemption for experienced drivers.

Book and attend the replacement appointment
In Absher: Appointments, Traffic, foreign-licence replacement. Choose an Eastern Province centre, upload both sides of the licence and the translation. Approved-country holders are processed without a road test, usually with same-day issuance; others take an assessment and a shortened course before testing.
Mobile appWho: YouInstant booking; days or weeks to the slotBooking around SAR 50; licence roughly SAR 80 / 200 / 400 for 2 / 5 / 10 years
5
Get the vehicle paperwork right before a causeway trip
You need a current Istimara registration in your own name, or a certified authorisation from the owner if the car belongs to a company, a spouse or a friend. Add short-term motor insurance valid in Bahrain, because standard Saudi cover generally is not. The causeway's own app handles the toll and, commonly, the temporary insurance.

6
Time the crossing deliberately
Outbound is worst on Thursday afternoon and evening; inbound is worst on Friday and Saturday nights. Eid and school holidays produce queues measured in hours. Crossing early Friday morning and returning before Saturday evening avoids most of it, and leaving the car on the Saudi side and taking a bus or ride-hail is a legitimate alternative.

Things most newcomers don’t know

Standard Saudi motor insurance does not follow you into Bahrain, and people find out in the queue.

Your Saudi policy is written for Saudi Arabia. Crossing with your own vehicle requires cover that is valid in Bahrain, bought short-term for the trip — commonly handled through the causeway's own app alongside the toll. Driving across uninsured is both illegal there and financially catastrophic if anything happens. It is a ten-minute purchase that is very easy to overlook on the first crossing, when you are focused on the exit permit.

A car that is not registered in your own name needs certified authorisation to cross.

Company cars, a spouse's car and a friend's car are all in the same category: the border expects either an Istimara in your name or a properly certified authorisation from the registered owner. This trips up people driving employer-provided vehicles, who reasonably assume the company's ownership is sufficient. Get the authorisation letter organised before the trip, because there is no way to fix it at the border.

The blood-type test on the Saudi licence exists for exactly this kind of road network.

The Efada medical bundles vision, colour vision and a blood draw, and the group is printed on the card so that responders have it at a crash scene. On heavily trafficked high-speed roads like the Dhahran–Khobar corridor and the causeway approach that is a sensible design choice rather than bureaucracy. Do the medical before the Absher appointment; the traffic office reads it from the system.

Camera enforcement here is dense, and the fines do more than cost money.

Eastern Province highways are extensively camera-monitored and violations post to your record without any roadside stop. Beyond the fine, an unpaid violation blocks issuance of your exit and re-entry permit — which in Al Khobar means a cancelled crossing rather than an abstract inconvenience. Check Absher and clear anything outstanding through SADAD as routine, not the night before you travel.

Common mistakes to avoid

Driving to Bahrain on Saudi-only insurance and discovering the gap at Passport Island.
Taking a company or spouse's car across without a certified owner's authorisation.
Assuming your country is on Muroor's approved list because a colleague from elsewhere converted easily.
Crossing on a Thursday evening or an Eid weekend and losing hours to the queue.
Leaving camera fines unpaid until they block the exit permit for a trip you have already booked.
