Turkey–Serbia Road Accident Cargo Claims Under CMR: Vehicle Defects, Unavoidable Events and Evidence

1. CMR applies to qualifying road carriage between Türkiye and Serbia

Article 1 applies to a contract for carriage of goods by road for reward where the contractual place of taking over and the place designated for delivery are in different countries and at least one is a Contracting State. Türkiye and Serbia are CMR Contracting States. Their current treaty status is recorded by the United Nations depositary.

The place of the accident is not the Article 1 test. A truck travelling from Istanbul to Belgrade can collide in Bulgaria; a vehicle travelling from Niš to Mersin can collide in Türkiye. The carriage remains analysed from the agreed taking-over and delivery points and the contract sued upon.

Identify the contractual carrier and the vehicle operator. The seller, buyer, freight forwarder, contractual carrier, subcontracted haulier and vehicle owner can be different entities. Article 3 makes the carrier responsible, within its terms, for servants, agents and other persons whose services it uses for performance. A contracting carrier cannot simply redirect the cargo claimant to the subcontractor without applying CMR.

Separate the cargo claim from the road-traffic recovery between drivers or motor insurers. The carrier may have recourse against a responsible third party, but that internal recovery does not automatically decide the carrier’s CMR liability to the cargo interest.

2. Article 17 starts from carrier liability for cargo loss or damage during the responsibility period

Article 17(1) makes the carrier liable for total or partial loss and for damage occurring between the time it takes over the goods and the time of delivery, as well as for delay. After a serious collision, the claim may involve several categories: goods destroyed at the scene, goods physically damaged, goods missing after salvage and goods delivered late.

Each category should be identified separately. A pallet destroyed in the collision is physical loss; a machine bent by impact is damage; cargo stolen from an unsecured accident site can create a later loss event; commercial losses caused solely by late delivery fall under the delay rules. Combining them into one figure can produce the wrong compensation provision.

The claimant should prove takeover, cargo identity, quantity and condition. Article 9 gives the consignment note prima facie evidential effect within the Convention’s terms. Loading photographs, package counts, serial numbers, seal records and warehouse scans can reinforce the file.

The carrier should preserve all evidence of the accident and its response. Article 17 liability is not determined by silence or by a generic statement that an accident occurred. The carrier’s defence depends on the facts it can prove.

3. A carrier relying on an unavoidable accident must satisfy Article 17(2) and Article 18

Article 17(2) relieves the carrier when loss, damage or delay was caused by claimant fault, claimant instructions not resulting from carrier fault, inherent vice, or circumstances the carrier could not avoid and the consequences of which it was unable to prevent. The last ground is the one most often invoked after a collision caused by another road user.

Article 18(1) places the burden of proving Article 17(2) causes on the carrier. The carrier should therefore establish how the collision occurred, what the driver did before impact, whether speed and following distance were appropriate, whether braking or avoidance was possible and what happened to the cargo afterward.

A third-party driver’s traffic violation is relevant but is not a substitute for the CMR analysis. If the carrier’s driver could reasonably have avoided the collision or reduced its consequences, the Article 17(2) defence can fail. Conversely, a sudden unavoidable impact despite proper driving can support the defence when proved.

The second limb also matters: consequences must have been unable to be prevented. After a collision, reasonable steps to secure the cargo, arrange recovery, protect temperature-sensitive goods or prevent theft can affect liability for subsequent loss. An unavoidable first collision does not automatically excuse every later consequence.

4. Article 17(3) blocks a defence based on vehicle defect or the vehicle owner’s fault

Article 17(3) expressly states that the carrier cannot relieve itself of liability by reason of the defective condition of the vehicle used for carriage or the fault of the person from whom it may have hired the vehicle or that person’s agents or servants. This is one of CMR’s clearest allocations of operational vehicle risk.

If the accident involved brake failure, tyre failure, steering defect, trailer coupling failure, suspension failure or another mechanical condition, preserve the technical inspection and maintenance file. The carrier may have contractual or tort recourse against a maintenance provider, lessor or manufacturer, but that is separate from the Article 17(3) position toward the cargo claimant.

Do not accept a generic “unexpected mechanical failure” explanation without evidence. Obtain maintenance dates, defect reports, inspection records, recovery-company observations and any forensic examination. If a component is replaced or destroyed before inspection, document the chain of custody and reason.

Article 17(3) also means that hiring the tractor or trailer does not transfer the CMR risk to the equipment owner as against the claimant. The contractual carrier’s external liability and its internal recourse should be kept separate.

5. A police finding against another driver is evidence, not the complete CMR judgment

Police accident material can establish positions, impact points, traffic violations, witnesses, road conditions and the identity of other vehicles. It should be obtained promptly and translated where needed. A final traffic or criminal decision can also be important evidence.

CMR liability, however, is governed by the Convention. A police conclusion that another driver was primarily at fault can support the carrier’s Article 17(2) defence but does not automatically establish the two-part CMR condition. The cargo court evaluates the evidence under the applicable procedural rules and the treaty standard.

The carrier may pursue the responsible road user or motor insurer after compensating the cargo interest. The claimant should not be forced to delay its CMR claim indefinitely while that third-party recovery is investigated. Article 32’s limitation period continues to require a separate diary.

If multiple vehicles or carriers were involved, identify whether the goods had already been transferred to another carrier before the accident. Successive-carrier provisions in Articles 34–40 apply only when their conditions are met; ordinary subcontracting should not be mislabeled.

6. Build two evidence files: accident causation and cargo quantum

The accident file should contain the official accident report, scene photographs and video, witness details, dashcam material, road and weather information, GPS/telematics, tachograph data, driver statements, maintenance records, vehicle inspection, recovery records and communications with dispatch.

The cargo file should contain the transport order, CMR/e-CMR, commercial invoice, packing list, serial numbers, gross weights, loading photographs, seal details, post-accident inventory, survey report, repair estimates, salvage receipts, destruction records and delivery documentation for goods that continued to destination.

Preserve the relationship between the two. A surveyor should know which pallets were in the impact zone, which were exposed during recovery and which were later transported in another vehicle. A single photograph of a damaged trailer does not establish the condition of every package.

For refrigerated cargo, preserve reefer power and temperature data through the accident and recovery period. For machinery, preserve alignment and commissioning tests. For electronics, preserve serial numbers and whether impact or moisture affected functionality. Cargo-specific evidence establishes actual damage rather than presumed damage.

7. Article 23 governs loss; Article 25 governs physical damage

For total or partial loss, Article 23(1) values the goods at the place and time of takeover. Article 23(2) refers to commodity exchange price, current market price or normal value of goods of the same kind and quality. The 1978 Protocol changes Article 23(3) to an ordinary ceiling of 8.33 SDR per kilogram of gross weight short. The United Nations treaty record lists both Serbia and Türkiye as parties to that Protocol.

For damaged goods, Article 25 requires compensation for the amount by which the goods have diminished in value, calculated by reference to Article 23(1), (2) and (4). If the whole consignment is damaged, the ceiling is the total-loss amount for the whole consignment; if only part is damaged, the ceiling is the total-loss amount for the affected part.

Repair cost can support the diminution-in-value assessment but does not automatically equal the Article 25 figure. A repaired machine can retain residual depreciation, while a repair estimate can exceed actual loss. The valuation should reflect the proved commercial position.

Article 23(4) separately addresses carriage charges, customs duties and other charges incurred in respect of carriage. Article 24 declared value and Article 26 special interest may alter the ordinary framework where their contractual requirements were satisfied.

8. Serious driving or safety conduct can raise Article 29, but the threshold must be proved

Article 29 deprives the carrier of Convention exclusions and limits where damage was caused by the carrier’s wilful misconduct or by default considered equivalent under the law of the court or tribunal seized. It also applies to servants, agents and other persons used for performance when they act within the scope of their functions.

A serious road accident does not automatically establish Article 29. The claimant must prove the conduct and the applicable equivalent-default standard. Allegations can concern deliberate violation of specific safety instructions, extreme driving conduct or knowingly operating with a serious defect, but legal classification depends on the evidence and the law of the forum.

Carriers should preserve tachograph, telematics, maintenance and dispatch records because Article 29 disputes often turn on what was known and how the vehicle was operated. Claimants should avoid using “gross negligence” as a substitute for factual pleading.

If Article 29 is established, the ordinary limitation and liability protections can change significantly. Forum strategy under Article 31 should therefore be considered together with the misconduct allegation, not after pleadings are already fixed.

9. Article 30 reservations, Article 32 limitation and Article 31 jurisdiction remain separate

Article 30 governs delivery reservations. Apparent cargo damage should be reserved at delivery; non-apparent damage requires written reservations within seven days, Sundays and public holidays excepted. If damaged goods are transferred to a replacement truck and delivered later, the consignee should still record the observed condition precisely.

Article 32 provides the ordinary one-year limitation period and the three-year period in the Convention’s wilful-misconduct/equivalent-default category. For partial loss and damage, time runs from delivery; for total loss, the special 30-day or 60-day starting rules apply. A written claim can suspend the period on the conditions stated in Article 32(2).

Article 31 defines the permitted international forums by defendant business connection, place of taking over, place designated for delivery and any valid agreed Contracting-State forum. The country where the accident happened is not, by itself, an Article 31 forum connection.

A police, criminal or motor-insurance investigation does not automatically stop the CMR limitation period. Keep the CMR civil deadline separate from every accident-procedure deadline.
