Do children need car seats in a cross-border car?

One-line answer: Yes — both Mainland and HK now require child restraints, with HK enforcing under-8 / under-135cm. Reputable operators provide 0–7-year-old seats (rear-facing, forward-facing, booster) free.

What if I'm bringing my own seat?

Bring your own — we install it. Most major brands (Britax, Cybex, Maxi-Cosi, Joie, Doona) work fine.

Liability points

• During an accident, an unrestrained child is not covered in the same way as a properly secured passenger (per most insurance terms)
• HK police can fine up to HKD 5,000 + 3 demerit points for non-compliance
• Drivers may refuse the trip if you arrive without proper restraints (we'll provide them on request — just plan ahead)

FAQ

How early should I request a child seat?

24 h ahead is enough for one seat. For 2+ seats, give 48 h notice.

Do you have rear-facing infant carriers?

Yes — Britax / Cybex / Joie infant capsules suitable for newborns up to 13 months.

Is there a charge for child seats?

First two seats free. Additional seats: HKD 50 each.

Can I use a baby sling / wrap instead of a seat?

No — slings are not legal child restraints and violate HK / Mainland rules. They also offer zero crash protection.

What about during the brief HKZMB disembarkation?

Carry the child or use a stroller. The seat stays in the car; you re-buckle on re-entry.
