Quick Answer — Tunisians drive on the right, and beyond that, local practice treats the written rules as a strong opening suggestion. None of it is aggression — it’s a different fluency, built on eye contact, the horn as language, and a shared assumption that everyone is paying attention. Most visitors acclimate within a day. The ten habits below are the ones that surprise foreign drivers most, from the passing-lane hierarchy to the taxi that stops mid-lane. Internalize them before your first roundabout, keep off rural roads after dark, and driving here becomes what it should be: the key to the whole country. Full logistics — costs, paperwork, insurance — are in our guide to renting a car in Tunisia.
Every country’s traffic is a dialect. Tunisia’s is fast, expressive, and — once you learn the grammar — surprisingly predictable. The mistake foreign drivers make is reading it through their home rulebook and concluding it’s chaos. It isn’t. It’s a system; it’s just an unwritten one. Here is the phrasebook.
1. Lane markings are advisory
A two-lane road carries three streams of traffic when needed; a three-lane roundabout is a single negotiated mass. Position, speed, and eye contact do the work paint does elsewhere. Hold your line calmly, signal your intentions with your whole car, and don’t defend “your” lane on principle — nobody else knows it’s yours.
2. The headlight flash means “I’m coming through” — not “after you”
This one causes genuine danger for northern Europeans, where a flash cedes priority. In Tunisia (as in much of the Mediterranean), a flash asserts it: I am not slowing down. When flashed, yield. When you flash, mean it.
3. The horn is a language, not an insult
A short tap says “I’m here” — approaching a blind corner, passing a cyclist, nudging a daydreamer at a green light. It is information, not aggression, and you should use it the same way. The long angry blast exists too; you’ll know the difference instantly.
4. Taxis stop where the fare is
Yellow taxis halt mid-lane, without warning, wherever a raised hand appears. Louages pull out of stations loaded and committed. Follow any taxi with one eye on its brake lights and both hands on the wheel, and leave the gap you’ll be glad you left.
5. Mopeds materialize from everywhere
Left, right, pavement, wrong way down a one-way, often unlit, sometimes carrying a family or a sheet of glass. The mirror-check that feels excessive at home is the baseline here. In medina-adjacent streets, assume a moped is currently in your blind spot, because one is.
6. Overtaking is enthusiastic — and oncoming traffic expects to share
On single-carriageway roads, the overtake happens with oncoming traffic visible, on the understanding that both outer cars will drift toward their shoulders and make a third lane in the middle. Drift graciously when it happens toward you. Attempt it yourself only once you’ve absorbed the rhythm — and never on the crest of a hill, which is where the local habit turns from custom into statistic.
7. Red lights have moderate authority at quiet intersections
At 2 p.m. on a busy boulevard, red means red. At a deserted crossroads, a slowing roll-through is common local practice. You should stop regardless — the rental car with foreign plates is held to the letter of the law, and the fine is yours — but don’t be startled by the car behind easing around you.
8. Roundabouts run on nerve and eye contact
Priority rules at roundabouts are honored unevenly; in practice, the vehicle that has committed has priority, and commitment is signalled by moving. Creep confidently, meet the other driver’s eyes, and go when the gap is real. Hesitation confuses everyone; decisiveness — not speed — is the safe setting.
9. Checkpoints are routine — relax
Police and National Guard checkpoints punctuate the roads, especially at city approaches and throughout the south. For a rental with foreign passengers, the norm is a glance and a wave-through. Keep passport, licence, IDP, and rental contract within reach, slow down early, be pleasant. Thirty seconds, and you’re rolling. (The broader security picture is in our Is Tunisia Safe? explainer.)
10. The night belongs to the unlit
The single rule every Tunisian will give you: don’t drive rural roads after dark. Unlit carts, unlit livestock, unlit pedestrians walking the carriageway, the occasional crater — the risk curve after sunset isn’t worth any itinerary. Plan every drive, everywhere, to end by dusk. This is the one habit on this list that isn’t negotiable.
The Reassuring Truth
Read cold, this list sounds alarming. Driven warm, it’s a system that works — Tunisian traffic flows on mutual attention rather than mutual rule-keeping, and within a day or two you’ll find yourself flashing, tapping, and drifting with the best of them. The fuel is cheap, the main roads are good, and the country beyond the rail line is the reward.
