Short answer: Vietnamese traffic police cannot hold a motorbike for just any stop — Decree 168/2024’s Article 48 lists the specific violations that carry temporary holding of the vehicle, alongside the fine. For motorbike riders the big ones are riding without a valid licence, riding a bike with no plates or defective registration papers, serious speeding, red-light running, riding on the wrong side or on the sidewalk, and violations connected to an accident. Holding is not a fine and not confiscation; it is custody of the bike until the violation is settled.

The list, precisely

Article 48 names which penalty clauses carry vehicle holding. For motorbikes, the operative items include:

  • Licence and age violations under Article 18 — riding with no or invalid licence, the under-age bands, and the related operator violations.
  • Registration and plate violations under Article 14 — no plates, fake or defaced plates, and registration-certificate defects serious enough for the K2 and K3 bands.
  • The serious road violations under Article 7 that the holding clause ties to — including red-light running (7(7)(c)), wrong-way and sidewalk riding (7(7)(a)), the higher speeding bands, and accident-connected violations.
  • Under Article 48(3), a rider stopped for any violation who cannot produce licence or registration papers on the spot can have the bike held until the papers are produced and the fine settled — this is the most common holding for visitors on rented bikes, and it is procedural, not punitive.

Holding versus confiscation

The decree keeps two different powers apart. Temporary holding (tạm giữ) is custody during processing: the bike is stored, the violation is settled, and the vehicle is released to someone entitled to receive it — usually the owner, with papers and proof of settlement. Confiscation is the transfer of ownership to the state and attaches to different findings — for example, fake plates are confiscated, a bike whose lawful origin cannot be proven can be confiscated under Article 14(5)(b), and Article 7(11) attaches confiscation to stunts and organised illegal racing-adjacent behaviour. A rider whose bike is merely held still owns the bike.

The rented-bike reality

For visitors, the practical impound scenario is Article 48(3): stopped without carrying a licence or registration, the bike is held until someone produces the papers. On a rental this means a call to the shop — the registration certificate and the rental contract are with the owner, and release normally runs through the owner or an authorised person, with proof of settlement of any fine. Riders should also know that a rented bike in Vietnam carries no exemption from the plate and registration bands; a shop’s paperwork defect is the rider’s stop.

Separating fact from practice

The law: Article 48’s list is exhaustive — holding only attaches to the listed clauses, and release runs through settlement. The practice: storage locations, release hours and who may collect vary by locality, and none of that is fixed by the decree. Foreign riders stopped in Hanoi should carry the rental shop’s phone number precisely because of this clause. What the police may not do is hold a bike outside the listed violations — a stop for a minor equipment item, for example, does not carry holding unless the rider also falls into a listed category.
