Yes, Iceland requires every child to travel in an appropriate car seat or booster that meets recognized safety standards, and there is no minimum age exception for tourists. Before you land, measure your child's height and weight, then prebook or pack a seat that meets UNECE ECE R44 or R129 standards. Confirm the exact seat with your transport provider ahead of time so nothing gets sorted out at the curb.
TL;DR:
- All child seats must meet UNECE standards R44.04 or R129 and be properly installed according to the manufacturer’s instructions.
- Prebooking a child seat with rental companies or private transfers ensures proper fit and compliance based on your child's measurements.
- Confirm that any rented or brought seat has a visible ECE certification label and is installed tightly with correct belt routing or ISOFIX connectors.
- Taxis and organized tours may or may not provide suitable child seats, so request specific models and certification details in advance.
- Checking the seat, installation, and angles at the pickup point before long trips helps prevent common errors and ensures safety.

What Icelandic law requires for child passengers
Iceland's child restraint rules come from Reglugerð um breytingu á reglugerð nr. 348/2007, which sets out that children must be secured using restraints that meet UNECE standards, either ECE R44.04 or the newer ECE R129. The regulation also states that these restraints must be installed exactly as the manufacturer instructs, and it does not permit adapting or using a seat in a way the manufacturer doesn't allow.
In practice, this means a seat that looks fine but is missing its certification label, or is installed loosely with the wrong belt routing, does not meet the legal bar even if a child is technically buckled in. Police in Iceland can and do check restraints during traffic stops, and a driver has the right to refuse a trip if a child does not have a suitable seat.
Before you book anything, have your child's age, height, and weight ready. These details help determine the correct seat category and allow a rental company, taxi dispatcher, or private transfer service to match the right equipment without guessing at the airport.
How to tell if a car seat meets the rules
Look for an orange ECE label sewn or molded onto the seat itself. It will read either ECE R44.04 or R129 (sometimes called i-Size), both of which satisfy Icelandic law under the amended regulation. R44.04 groups seats by weight, while R129 groups them primarily by height and includes more rigorous side-impact testing.
As a rough guide, infants ride rear-facing in an infant or convertible seat, toddlers move to a forward-facing harnessed seat once they outgrow the rear-facing limits, and older children use a high-back booster until they reach the height threshold set in the regulation for using an adult belt alone. Always check that the seatbelt routes through the correct guides, and if the vehicle has ISOFIX anchors, confirm the seat is ISOFIX-compatible rather than forcing a fit. The seat's own manual, not general instinct, is the final word on installation.
Where to actually get a compliant seat in Iceland
Most rental car companies list child seats as an add-on, but availability and correct sizing are not guaranteed unless you reserve one in advance. Taxis vary widely: some carry a booster or two, many carry none, and a driver is within his rights to turn away a fare if there's no suitable restraint for a child on board.
Bringing your own seat from home solves the sizing question but adds its own friction. Most airlines allow car seats as checked baggage at no extra charge, though you'll want to confirm your specific airline's policy and check that your seat's installation method (LATCH or seatbelt) works with Icelandic rental vehicles. For families who want certainty without hauling gear through an airport, a private transfer that confirms your child's seat by age, height, and weight before you land removes the guesswork entirely.
- Rental cars: seats often available, but only reliable when prebooked.
- Taxis: hit or miss, and a driver may decline the trip without one.
- Private transfers: seat confirmed in advance, matched to your child's measurements.
- Bring-your-own: check your airline's baggage policy and confirm the seat fits Icelandic vehicles.
Practical safety and installation tips for travelers
A seat that meets ECE standards still has to be installed correctly to do its job, and rushing this step at the airport is where most mistakes happen.
- Read the seat's manual before you travel, even if you've installed it before, since rental vehicles differ from your car at home.
- Route the seatbelt or ISOFIX connectors exactly where the manual shows, not through the nearest gap.
- Tighten the harness until you can only fit one or two fingers under the straps at the collarbone.
- Check the recline angle for infants, since a seat that's too upright can affect breathing on long drives.
- If the vehicle has ISOFIX anchors, use them and confirm you hear or feel the connectors click into place.
Common errors include a belt that's loose enough to shift on impact, a harness sitting too low or too high on the shoulders, and seats that are past their manufacturer's expiration date or subject to a recall. Check the certification label for a date stamp and model number before you rely on it.
Pro Tip: Ask the pickup driver or rental desk staff to double-check the installation with you, and do a short test drive before setting off on a longer route like the Ring Road.
Taxis, buses and organized tours: what to expect
Practice on the ground varies more than the law suggests. Some taxi companies and tour operators carry child seats as standard, others don't carry any, and driver discretion plays a real role in what actually shows up at pickup.
If you're booking a taxi or a tour, request the child seat in writing and ask for the specific model and its certification standard, not just a vague confirmation that "a seat will be provided." Mention this when researching minibus options for school groups too, since larger vehicles have their own seating logistics. If a seat doesn't materialize at pickup, your options are to delay and wait for another vehicle, ask for a swap, or fall back on a private transfer booked specifically with your child's measurements on file.
Your airport-to-car checklist for families
Getting this right starts before you board your flight and finishes with a quick check at the curb.
-
When booking, give your child's age, height, and weight so the right seat is waiting.
-
On arrival, check the seat for its ECE certification label before accepting the vehicle.
-
Test the harness snugness and confirm the installation looks tight and correctly angled.
-
Take a short drive around the lot if anything feels off before committing to a long trip.
-
If the seat isn't right, ask for a different vehicle or switch to a prebooked family transfer that has already confirmed the model.
Packing efficiently also helps: a kids' travel wardrobe checklist can free up luggage space for the car seat itself if you're bringing one from home.
Why prebooked family transfers take the guesswork out of arrival
The families who have the smoothest arrivals in Iceland are the ones who confirmed their child seat before they ever boarded a flight. Flight delays, unfamiliar rental counters, and tired kids make the airport a hard place to sort out equipment on the spot. A transfer that already knows your child's age, height, and weight and has flagged the correct seat in advance removes that pressure entirely, and that's the version of this trip we think every family deserves.

Booking a family transfer with the right child seat
Planning transportation around a child's exact measurements shouldn't add stress to a trip that already has enough moving parts. At Easytransfer, you can request a child seat directly when you book a private transfer, whether that's a Keflavík Airport pickup or a ride out to the Blue Lagoon or Sky Lagoon.
When you book, just include your child's age, height, weight, and your flight details, and the right seat will be ready when your driver meets you. Every transfer comes with flight tracking, so a delayed landing won't leave you or your seat request stranded, along with fixed pricing and free cancellation up to 24 hours before pickup.
- Provide child age, height, and weight when you submit your booking.
- Add your flight number so your driver can track arrivals and adjust automatically.
- Confirm the seat model in your booking notes if you have a preference.
- Reach out any time with questions, since support runs 24/7.
If your trip includes a day tour like the Golden Circle or South Coast, mention your child seat needs there too so the same seat travels with you for the full day. Get a quote through Easytransfer with your pickup and drop-off details, and a member of the team will confirm your seat and vehicle within 24 hours.

FAQ
Can my 9 year old be out of a booster seat?
It depends on your child's height rather than age alone, since Icelandic rules tie the requirement to reaching a height threshold where an adult seatbelt fits properly. Many children still need a booster, so check your child's height against the seat's guidance before assuming they've outgrown one.
Can a 20 year old drive a rental car in Iceland?
Rental car age requirements are set by individual rental companies rather than by the car seat regulation itself, and they commonly require drivers to be an age requirement that varies by provider and vehicle category. Check the specific rental company's policy directly, since minimum ages and any young-driver surcharges vary by provider.
Can you turn right on a red in Iceland?
No, turning right on red is not permitted in Iceland unless a specific sign or signal indicates otherwise, which differs from common practice in some other countries. Drivers should treat red lights as a full stop unless a dedicated arrow or sign says otherwise.
What age is a 13kg car seat?
A seat rated up to 13 kilograms typically fits infants from birth up to the infant stage, though the exact fit depends on the individual child's growth rather than age alone. Always check the seat's own weight and height limits on its certification label rather than relying on age as a stand-in for size.
